I need to spend some time on it but I purchased two Omada APs to pair with my OpenWRT router thinking roaming would just work with mostly Apple devices. That didn’t happen. I’m hoping some of this article applies and I can improve the situation a bit.

andor• 2 months ago

For Omada devices, you need a "Controller". You can run the Omada Controller software on an existing computer, get one of their controller devices, or use their cloud-based service, which should be free at your scale.

neogodless2• 2 months ago

The Omada device* I researched also supports standalone mode and hosts the web UI like any other consumer router.

I’m pretty happy with my Omada controlled EAPs around my house.

Running Omada on my Windows Server was painful (doesn’t really run properly as a service, software updates are a chore), but since I moved it to run on Proxmox using a super simple LXC image (I maybe got terminology wrong here) it’s been very nice.

Supposedly I should have excellent roaming between the APs, but I’m not sure how to check. Certainly, walking from one end of the house the other while on a Teams or WhatsApp call on my phone has maybe only a super minimal amount of time that I might not hear the other person (sub second for sure, if at all), but mostly I don’t notice.

biggc• 2 months ago

I had a hell of a time getting WiFi roaming to work in my house between Omada APs in a low-interference suburban neighborhood.

Any combination of 802.11r and k/v seemed to just cause my phone's connection to drop for minutes at a time when moving around the house.

I wish I could remember my exact solution for you, I believe I just turned off 802.11r and k/v, set channel selection to automatic, and undid any manual or automatic power tuning.

jauntywundrkind• 2 months ago

I'd used DAWN for band steering/roaming at my last place, which worked ok. uSteer is a little newer & is an official openwrt project. https://github.com/berlin-open-wireless-lab/DAWN https://openwrt.org/docs/guide-user/network/wifi/dawn DAWN has a wild amount of knobs to tune, which aren't super well described. I haven't been running it since a single AP covers my current place very well. But it would be interesting to go evaluate DAWN & it's config with an LLM, to dice in & see more. uSteer too.

Great write up, good information to share. This really is such an important next step for many people's wifi and it's documentation is pretty so-so.

goodburb3• 2 months ago

You can stick to 802.11r only by lowering the transmission power and have all the APs on the same channel, in my tests it ended up switching much faster than K/V. (~75ms)

On iOS, equal channel with correct ESS will switch liberally. On Android 14+ with Broadcom chip it will start conservative, then switch liberally after the first poor signal switch-over event, up until disconnection.

Android (Pixel/Moto) will never switch (even with K/V) on large network activity, only VoIP/video call. It depends on vendor implementation. [0] I use "dp.logcatapp" log reader while roaming, "com.android.location.fused" can be used to show score and current load.

Samsung is known to push protocol support early: 802.11r in 2013, 802.11w 2015, some models do not use Android's default connectivity manager.

To add, WPA3 with 802.11r is known to have issues on Apple hardware before 2021 on all iOS versions, many Android devices, especially smart TVs don't support it, will not connect or are unreliable (protected beacon frame), can be searched in buried report results at OpenWrt forum mega threads and Ubiquity. WPA2+FT and forced MFP with a long password is a safe alternative. 802.11r use PMK push on WPA3 compared to WPA2, which was known to be problematic on older hardware.

802.11K/V is more suitable for campus and load balancing, tuning it based on RSSI and station metrics is very difficult, enterprise hardware rely on network traffic and air time.

To be fair, I don't require my 85" TV to roam, as it's not as portable as my iPhone.

basilikum• 2 months ago

Glad it works for you.

I need my TV to rapidly switch APs in very heavy load wide area networks with thousands of devices while I'm cruising through the venue with my motorized couch and entertainment system.

Now I want to actually build that for GPN24 next week. Wouldn't use AndroidTV for that though.

keanebean86• 2 months ago

Good luck watching the office when your cat pushed your upstairs AP off the balcony. Your tv won't auto switch to the downstairs AP which is now closer than the one that's suddenly in the driveway.

cj• 2 months ago

Until it gets stuck on a far away AP because it was the first AP to come online the last time the network rebooted.

Not sure if roaming is actually the fix for this problem. For whatever reason my Ring cameras just love connecting to the worst and most far away AP in my house.

dheera• 2 months ago

On my Unifi setup at home with multiple APs I had to disable 802.11r to get things to roam fast. I have Android and Linux laptop, wife has iPhone and MacBook.

With 802.11r on, things would disconnect for 60+ seconds before reconnecting. It was a constant frustration of "arrrrrrrggghhhh fucking connect damnit I'm standing a meter in front of the AP can't you fucking see it fuck fuck fuck just connect, it's right THERE, connect NOW, arghhh" and then it would completely disconnect (no wifi found) and then reconnect a minute later.

With 802.11r off things just roam smoothly. I guess the people who inventned the tech didn't test it thoroughly enough.

simoncion6• 2 months ago

It might be that UBNT has screwed up the settings when in 802.11r mode. I have 802.11r set up on my OpenWRT Ones and I'm seeing what appears to be A-OK roaming with my Linux laptop and Pixel 5a. I do also have DAWN installed (solely to populate the "hearing map") and umdns installed... but it's not clear to me if those are actually useful.

Unless they've reimplemented the whole damn thing since like 2018 or so, UniFi is OpenWRT with the serial numbers filed off, and UBNT is known to be not especially great at having good software on the APs. I had a square UAP-AC and then an AC-LITE and an AC-LR all running the official software for several years. While the management GUI seemed like it'd come in handy if you had to manage like a hundred APs, I wasn't impressed with either official support or the rest of the software.

supertrope4• 2 months ago

Once you're not using default settings, here be dragons. In theory 802.11r is a standard. In practice enabling 802.11r puts you into the minority of users who do so. There's a lot less quality assurance coverage there.

You're at the mercy of UniFi not having any show stopping bugs (haha), the client device supporting 802.11r or at least tolerating it, and the interaction between UniFi and the client not having any show stopping bugs.

rcarmo13• 2 months ago

Yeah, I tried the same channel thing, but I can't change the power, really - the flat is wrapped around two elevator shafts :)

goodburb3• 2 months ago

The elevators are probably causing rapid blind spots (shadows) while the user is moving around, 802.11k is indeed useful in this case for cutting down scan time, since iOS will still scan with filtered channels.

It's an interesting setup, looking forward to an update.

js2• 2 months ago

Apple has some minimal recommendations as well:

https://support.apple.com/en-us/102766

KennyBlanken• 2 months ago

You can stick to 802.11r only by lowering the transmission power and have all the APs on the same channel

Fast roaming has not, does not, and never will require APs be on the same channel. Only the SSID and password needs to match.

Setting them to the same channel will cause the APs to interfere (when they can't "hear" each other) or block each other from transmitting, or both. You set APs near each other so they are on non-overlapping bands. Always.

This is basic WiFi networking 101

Samsung is known to push protocol support early: 802.11r in 2013

802.11r was released in 2008 and rolled into 802.11-2012.

Also, the iPhone 5S (2013) has 802.11r support.

goodburb3• 2 months ago

Fast roaming has not, does not, and never will require APs be on the same channel. Only the SSID and password needs to match.

There were no mentions of requirements for 802.11r in the comment. You removed "much faster than K/V." from the quote. "only" was referring to 802.11r exclusively. You can have the same results with different channels with K/V, provided that the clients support it as the rest of the comment mentions.

802.11r-only on different channels is ineffective for devices without K/V, since the reductions are insignificant.

You will be shaving 100ms from a 700ms delay on scan and association, compared to no-scan association which is around 20ms, hence the 75ms note.

And even then, FT is only needed for short buffer streaming like VoIP and VoWiFi. It's more important for WPA3, since handshake roundtrips are even longer (~300ms) which can degrade video/voice internet calls with a lengthy time to recover and complete silence for second or two on VoIP, it's not really needed for the average user back when WPA2 was standard.

Android and iOS will first scan on the same frequency, then rotate through the channels, which is now even longer on 6Ghz capable devices with the total number of channels.

The transition time is significantly faster with equal channels on most hardware, this is where 802.11k helps with different channels, especially in iOS. Without it, they cache scan results provided that the farthest AP is detected, this rarely happens since the scan time is so short.

Scanning different channels while connected causes large amount of jitter on station optimized WiFi SoCs, affecting VoIP on mediocre connections while the user is moving and actively losing signal, so its done as quick as possible, often missing many beacons. They can scan longer on the same channel without degradation. [0]

Without K/V, iOS/Android goes to the extent of doing frequent rescans on low network activity on body movement, you can install a Wi-Fi diagnostic profile to view the current activity on iOS, logcat on "fused" for Android.

The suggestion doesn't bash on 802.11k/v, it's just a compatibility alternative, considering that very few clients support it, let alone off the shelf consumer AP support.

Setting them to the same channel will cause the APs to interfere (when they can't "hear" each other) or block each other from transmitting, or both. You set APs near each other so they are on non-overlapping bands. Always.
This is basic WiFi networking 101

This is only true under large air time traffic and in large scale indoor setups. Not satellite APs that are far. Qualcomm, Mediatek and many systems implement their own spatial reuse technology. WiFi 6+ introduces BSS coloring for channel width overlaps to further improve speeds on mixed traffic, not to mention the generally low penetration / TX power of 5Ghz+ on SNR.

> Samsung is known to push protocol support early: 802.11r in 2013
802.11r was released in 2008 and rolled into 802.11-2012.
Also, the iPhone 5S (2013) has 802.11r support.

The Samsung line in the comment was referring to Androids, many Android didn't support these until 2020, some non-flagship still don't (disabled), Samsung was notable to include it early, there are three paragraphs underneath referring to old phones and smart TVs, both Androids. It is not enabled by default on many off the shelf APs for these reasons.

amaccuish• 2 months ago

You can stick to 802.11r only by... have all the APs on the same channel

Is that really true? We make sure all our APs are on different channels to prevent interference.

ghrl• 2 months ago

I don't quite understand the benefit of the setup. If there are legacy IoT devices that need unique named 2.4G network, just broadcast another SSID for them. So each router broadcasts main 5G (common name, fast roam etc), main 2.4G (same as above) and legacy IoT 2.4G (with a different name for each AP, and possibly worse encryption and maybe even TKIP). That wouldn't hold back the network for legacy devices.

toast03• 2 months ago

I run a single ssid dual band network ... what tends to happen is 5Ghz is effectively ignored. 2.4Ghz has better coverage, so everything wants to live there. At least wifi 6 brought improved encoding to 2.4Ghz.

I haven't had luck with the roaming extensions; when I run them, some of my devices won't connect or won't stay connected and it's a pain to monitor. I guess I could run a different SSID with roaming enhancement, but effort.

opan• 2 months ago

You can turn down the power on the 2.4GHz radio so it's not as overpowering.

lxgr7• 2 months ago

This used to be pretty common on at least Linux and Android clients some years ago.

Not sure if they finally got around to making the BSSID selection algorithm a bit smarter or whether all my access points just support active steering at this point, but I haven't seen this in the past couple of years.

ssl-36• 2 months ago

That's been my experience as well.

My workaround for part of that is using many SSIDs.

A. The SSID that covers both bands, in all areas

B. Two more SSIDs, one for each band -- again, used in all areas

C. Another SSID just for the AP in the garage (which also has A and B SSIDs)

It has some advantages: I like being able to set a portable device to SSID A. These things usually figure it out well-enough while moving around. When someone visits and asks for wifi access, I give them SSID A. It works; it's just not always perfectly ideal.

It also prevents fixed devices in the garage from deciding to use APs in the house; it never works well for them when that happens. (The opposite problem hasn't been observed to be an issue yet.)

And it lets me decide whether any device is able to use 2.4 or 5GHz, in the usual way of having per-band SSIDs. If my TV streamer weren't plugged in with ethernet, then I'd set it to use the 5GHz-only SSID.

---

A big downside is that it's ugly. Another is that the per-device config is spread out amongst all of the devices instead of centralized, but that's not so bad: I just make the SSID decision at initial device setup and forget about it.

Marsymars3• 2 months ago

I run a single ssid dual band network ... what tends to happen is 5Ghz is effectively ignored. 2.4Ghz has better coverage, so everything wants to live there.

That hasn't been my experience at all. Checking my current network status, I've got 24 devices connected to 5GHz and only two devices (my two Nest Doorbells, for whatever reason) connected to 2.4GHz that also supports 5GHz.

neogodless2• 2 months ago

My current experience is that out of ~20 devices, about 6 are on 5Ghz and the rest choose 2.4Ghz. And it's basically perfect.

Because the 6 devices on 5Ghz: laptops and smartphones.

The rest are "smart" devices that work perfectly on 2.4Ghz.

rcarmo13• 2 months ago

I _am_ broadcasting a second SSID, in case that was not obvious from the text... I just don't want there to be 3.

ruptwelve• 2 months ago

When I move from Europe to the US I realized that roaming is not as prevalent here as it is back home. The (mostly) wooden houses enable me to just use one really powerful AP for most of my needs.

Jabdoa2• 2 months ago

You can also "just" set the 802.11k entries manually. Add 802.11r and you should be mostly good. Usteer makes it slightly better by moving clients to the best AP when they stay stationary for longer whiles.

rcarmo13• 2 months ago

Yeah, that is actually what the OpenWRT package does, except it grabs the data for me. Saves me the scripting :)

pickdan• 2 months ago

There is a pretty interesting option "nrsyncd" that uses UPNP rather than having to add the 802.11k entries by hand/script. Seems to work quite well, takes a few minutes to gather the information about the other devices. https://github.com/Fail-Safe/nrsyncd/blob/main/README.md

thenthenthen• 2 months ago

Cool! I dont need this anymore since im broke and moved to a 1 room apt. but yeah the ‘set the same ssid’ “trick” def. is not enough and often achieves the opposite effect.

lxgr7• 2 months ago

The obvious advice for roaming is “use one SSID everywhere”, and that is often correct if you’re running Wi-Fi in an office, a public venue, or generally somewhere where you don’t have (or care about) legacy devices.

What difference does the presence of legacy devices make? Is the intent to isolate them from modern devices from a network perspective? Then create a separate SSID on both 2.4 and 5 GHz for modern devices.

I can't think of any legitimate reason for split SSIDs anymore. Linux clients used to be pretty bad at preferring 5 over 2.4 GHz if RSSIs were both excellent but 2.4 was slightly better, but I haven't seen that in years.

rcarmo13• 2 months ago

There is zero benefit to using 2.4 for me, really, since it's crowded as heck. I'd rather skip it altogether.

lxgr7• 2 months ago

If you don't need it, of course, you might as well deactivate it. But if you do, I don't see the point of having two different SSIDs if you don't need them for another reason anyway.

fullstop3• 2 months ago

It penetrates walls so much better than 5GHz. If I lived closer to my neighbors I would agree with you.

Plus I still have some esp8266-based widgets that I made which only operate on 2.4GHz.

drnick12• 2 months ago

Most IoT devices support 2.4GHz only. Notably this applies to ESP32-based devices and older phones and laptops too. I would argue that it is the 5GHz band that is optional, the only benefit (bandwidth), being relevant only for laptops and phones when downloading something.

esseph6• 2 months ago

I can't think of any legitimate reason for split SSIDs anymore.

Different networks / vlans / firewall rules.

lxgr7• 2 months ago

These are all not splits by frequency, though.

simoncion6• 2 months ago

I have my RADIUS server put supplicants coming in on SSID "A" on one of the VLANs that gets RPZ-based adblocking, and SSID "B" on one of the ones that gets no adblocking. It's pretty fun and easy.

jon-wood• 2 months ago

Many APs now support either using Radius and username/password auth for this, or having multiple acceptable pass phrases for a WPA2 network which drop devices into different VLANs.

craftkiller2• 2 months ago

I've seen claims that the wifi 6E spec mandated that 6ghz networks required WPA3, so you would need to have a separate WPA2 ssid for legacy devices which therefore couldn't include 6ghz. A lot of access points now support a single SSID with all 3 bands using both WPA2 and WPA3, but I don't know if that is due to a change in the spec or if access points are violating the spec by offering that.

lxgr7• 2 months ago

Can’t one SSID support different WPA versions across APs? I’m pretty sure all my devices just shrugged and connected when I downgraded my (single AP) SSID from WPA3/2 to 2 only and back up to 3/2.

Which is a bit sad, but also seems like it would allow this use case perfectly (assuming this was done on purpose and not just an oversight).

wwweeee• 2 months ago

Using only 6ghz, turned off 2.4 & 5. Problem solved.

Chihuahua0633• 2 months ago

How's that working out for your IoT Devices?

TimTheTinker4• 2 months ago

Not to be that guy, but...

If you want multiple SSIDs, roaming, daily neighbor scanning and auto channel selection, etc, but don't like to spend hours tinkering with your equipment beyond the physical setup, then Ubiquiti UniFi equipment is great.

I stopped recommending UniFi around 2020 (several of their best engineers had left, and they made some dumb choices), but IMO they're back to being a decent choice. And I appreciate that they're become a one-stop solution for all home/SOHO as well as mid size enterprise IT needs.

bdavbdav2• 2 months ago

Yep exactly. This stuff quickly falls into “choose your battles” for me, and I’d rather just offload the issue

rcarmo13• 2 months ago

As long as you're happy with having your home wi-fi potentially controlled by the cloud...

rcarmo13• 2 months ago

Ubiquity would have added another zero (at least) to the price here and bring cloud features I very determinedly did not want to have in the first place (check the original post at https://taoofmac.com/space/reviews/2025/09/14/1630).

This wasn't hours of tweaking. Well, over almost a year, maybe two hours, but no more than that.

Saris• 2 months ago

Unifi doesn't have any cloud requirements that I know of. But yes they are more expensive than the hardware you've got, at $100 per AP.

For my needs unifi was worth it to not have to deal with OpenWRT again, or worse, stock firmware on consumer APs.

goodbirb4• 2 months ago

99% of what he did is not needed. Only 2 things are needed: enable fast roaming (FT), and change DTIM from the openwrt default of 2, to 3. That's all. No need to install usteer, extra hostapd fields. Nothing.

By lucky chance, while he set up usteer, he modified DTIM to 3 thus fixing the fast transition roaming, which doesn't work well on default openwrt because of DTIM. Especially Apple devices really hate DTIM=2 (they need the extra off-time given by DTIM to properly scan the other channels).

rcarmo13• 2 months ago

Actually, no. DTIM was always 3, if you'd bothered to read the original post - https://taoofmac.com/space/reviews/2025/09/14/1630

I do know what Apple devices "like" (it's kind of my thing, hence the domain name).

supertrope4• 2 months ago

With UniFi access points I found 802.11r to be unnecessary. I lowered transmit power so each room only has one AP providing a -67 dBm signal or stronger. 802.11k is enabled by default and is especially important if you use DFS channels. You can enable 802.11v with the BSS transition setting. I verified with Wireshark that my iPhone requests a 802.11k neighbor report, the current AP responds with a neighbor report containing a single candidate AP, and my iPhone roams to the next AP. Internet phone calls do not drop when walking between rooms. That is the only application that requires seamless roaming.

goodbirb4• 2 months ago

802.11r is pretty important, it's what allows the phone to skip the slow 4-way handshake when transitioning to new BSS.

acidburnNSA• 2 months ago

I spent a long time recently setting pretty much this same thing up. When in my office my Android phone battery rapidly died, I guess because usteer kept trying to steer it or something. I ended up turning off usteer and 802.11r and just deal with slow roaming. Maybe I should try again with the static neighbor reports.

raj_db_dev• 2 months ago

Curious if you think usteer is viable without wired backhaul. I have two OpenWRT routers in different rooms in differnt part of the house and not possible to connect them by ethernet. Would the usteer overhead make things worse if they're just communicating over wifi?

bobbob1921• 2 months ago

I do a lot of work on very large Wi-Fi networks (i.e. hotel/apartment complexes with 80 to 500+ access points), for a very rough quick test of coverage quality and roaming performance, find a Ping app for your phone that allows you to set a super low interval (i.e. time between pings sent), and ping your gateway router (i.e. 192.168.1.1) and while that is running walk around your home/location. It’s important that the Ping app keeps sending pings even if they drop, i.e. it should just look like a waterfall/constant stream of fast pings that show you red/green pings and ideally a summary at the end. On iOS the app I tell people to use is called “Ping” with a blue icon, I usually have to share the link to the app as there are several with this name (I’m not on my phone currently or I would share the link) there are several ping apps that do offer this fast ping feature.

Question for the wifi experts in this thread...

What's a good off the shelf multipoint wifi system these days? I have Amazon's Eero right now and it's ok.

You're going to have a hard time really beating Eero.

The main downsides to Eero are the cloud requirements and limited configurability - if those aren't a problem for you it's a very nice system.

If you want to go pro-sumer, these are great:

https://store.ui.com/us/en/category/cloud-gateways-wifi-inte...

And if you need more coverage or other networking gear at a later point, you can just tack on another access point or a switch or something, and it all works together seamlessly through a single interface

drnick12• 2 months ago

I still like the TP-Link E610 (flashed to OpenWRT) better. They are more compact and presumably more durable than "residential" devices. I also dislike anything that has "mesh" in its name.

To me at least, the gold standard for a large home is a standalone cable modem or ONT connected to an x86 PC that serves as home server and router, and as many ceiling mounted APs as necessary to ensure good WiFi coverage. No cloud, apps, or proprietary software anywhere. With such a networking backbone it is also easy to integrate self-hosted security cameras and other appropriately hacked IoT devices.

porjo• 2 months ago

I use the (older, lower spec) TP-Link EAP225 with Openwrt and it's been great standalone. The single ethernet port is slightly annoying for a router, but PoE makes up for it.

With Wi-Fi 8 we will finally get steerable friendly roaming like cellular radio is doing for almost 40 years now.

This "here's a neighbor table, disassoc and fuck you&good luck"-method we must use right now is just super painful. It's super complicated to build reliable networks that way.

iPhones, iPads and MacBooks would not switch to another AP

About a decode ago when debugging networking issues in an office, we had the observation that Apple hardware holds onto access points for dear life. Everything else would roam fine, but Apple would stay connected to distant access points with awful signal as if Steve Jobs' life depended on it.

tarunupaday• 2 months ago

That behavior has changed a lot in the past decade. Apple actually documents their roaming thresholds.

The signal has to drop below -70dbm for ios and -75 dbm for macos for the devices to consider roaming. Additionally, the difference between the two AP has to be 8db for ios and 12 db for macos.

https://support.apple.com/guide/deployment/wi-fi-roaming-sup...

IMHO, these are good defaults. Apple devices are optimizing for stability over the “best” possible signal.

What you might consider awful signal difference between the two APs might not be. (e.g. a mac device at -75dbm need to find another AP with -63dbm or better.)

Havoc• 2 months ago

Same - split by frequency & each does something else. Kept IoT separate because I want to put that on a separate AP that plugs straight into firewall so that I can hard segregate that stuff on physical wire & write opnsense rules against the port.

I've also moved primary mobile devices to 6ghz & putting in 10gig fiber for stationary devices.

hxii• 2 months ago

Curious to know why not use DAWN instead? And specifically because I'm still trying to find the optimal settings for my own setup with three APs.
