Yes, it does in that I need to deliver 802.3af/802.3at somehow, even if that is with a midspan injector.

I've been doing some additional reading and might skip it in favor of another EAP-225 since it apparently doesn't support roaming. Unfortunate since my wife would prefer this form factor in the living room.

Thanks

Hi @unmesh,

The wall unit does support basic roaming, but not Fast roaming as I recall.  Keep in mind for Fast roaming you also need to run Omada/SDN 24x7 (on a PC or OC-200) and need to have modern clients which support it.  Generally speaking, basic roaming works just fine in most cases.

The EAP225V3 or 245V3  when ceiling mounted (on a white sealing) is also not that noticeable -- despite the somewhat futuristic (aka weird) shape.

I do run the SDN controller.

Not sure which of iPhone IoS, the latest MacOS and Windows 10 support Roaming, Fast or otherwise

Generally speaking, most client devices which support 802.11ac also support Fast Roaming.  So most devices made in the last 2 or 3 years including including iOS, MacOS, and Windows.

All Wifi devices support basic/normal roaming -- for the past 15+ years.

Fast roaming just reduces the handover latency from one AP to another so it reduces application glitchiness when using VOIP (aka Wifi Calling) or streaming video/etc. during handovers.

For 95% of users, basic roaming works just fine.

@JSchnee21 Maybe its different on the new arm based macs, but I don't think any mac's support 802.11k/r/v, only iOS.

Hi @mackworth,

You are right.  All modern iOS devices support it

https://support.apple.com/en-us/HT202628

But, MacOS is definately late to the party.  I've spent 10-15 minutes googling it and haven't found a definitive answer.  Certainly it seems all MacOS versions prior to 10.14 do not support 802.11r -- as you suggested.  Where it gets a little unclear is with 10.15 and Big Sur.  I'm seeing some potential evidence of support, but still lots of issues (if it works at all).

Intel NIC support

Based on the Intel link above, it looks like Windows versions prior to Windows 10 do not support Fast Roaming at all (even if the NIC hardware does).

Additionally (at least as of the writing of the Intel note), Windows 10 is only supporting Fast Roaming for enterprise (e.g. Radius) encryption and not PSK (like we use at home).

I actually wasn't aware that Fast Roaming device support was so limited.

So many people are asking about it now -- mistakenly thinking that it is "necessary" somehow -- not realized that devices have been performing basic roaming without it for 15+ years.

-Jonathan

Yes, so far, from what I can find, Windows 10 only supports 802.11r when 802.1X is used

@JSchnee21  yeah I didn't realize MacOS didn't support it until I set up my APs and was wondering why my phone would switch APs but my laptop would be sticky. I have updated to Big Sur and should test again.
