Hi, I have 3 R310 unleashed AP’s, connected by wire (no roaming).

two are on the ground floor (attached to ceiling), one on the second floor, facing down.

when I am on the first floor, my clients (iPhone) keep connecting to the R310 attached on the ceiling of the floor below (ground floor). Network speed on 5ghz is then around 70mbit.

when I disable the AP on the ground floor, the clients connect to the one on the second floor, resulting in much higher internet speeds (150mbit).

I tried lowering the transmit power on the ground floor in order to get clients moving to the AP upstairs, but I need to lower till 1/4 in order to let clients switch to the AP on the second floor. This also results in too limited coverage on the ground floor and garden.

any tips what I can do?

thank you

Ok, so I have experimented a lot and finally configured my 3 r310’s as follows:

Separate ssid’s for 2.4 and 5 GHz
Fixed channels 1,6,11 on 2,4
Fixed channels 36, 44, 52 on 5
Channel width on 5 ghz to 40mhz
BSS-minrate on 12 (both ssid’s)
OFDM-only mode enabled (both ssid’s)
802.11k enabled (both ssid’s)
802.22r enabled (both ssid’s)

still a little stickiness on some devices, so also enabled:

802.11v smart-roam level 3

now works perfectly!

No client stickiness and no devices connected to the wrong AP’s.

As an advice for others, it is very beneficial to name your AP’s based on their location, and validate if the clients are connected to the most logical (nearest) AP. All my devices have connectivity level 'excellent' right now.

If it's helpful for others, I am willing to share all the SSH commands. Please let me know if needed.

Any tips or follow-up advices are welcome!

Two more questions: do I need to disable background scanning when using fixed channels? And how can I check in the logs if DFS is triggered?

As suggested by another poster, as long as your clients support it.. try turning on 802.11k, 802.11r, and 802.11v.

I know 802.11k and r are in the webGUI.

However, 802.11v seems to be needed to activated in CLI.

Please see this thread on

@hayward_kong thnx! Wondering though, what I understand of 802.11v, the client gets kicked when signal strength is below a certain threshold, correct?

I still like coverage in the end of my garden, which is limited, but more then enough. Will that be impacted as well, e.g. will I have the risk of having no coverage in the garden at all?

second question: I do have a lot of iPhones. But might there be devices that are impacted negitively by enabling 802.11v (and k and r)? E.g do all my devices need to support v k and r? I have no way to guarantee that.

Hi Jan,

Most of modern devices support these features. If you are not sure, just look for the specifications of any of your devices, which is older or which you think doesn't support it.

jan_willem_henn · ‎03-19-2021

thnx, but if it doen't support, will it give issues? are the technologies backward compatible?

syamantakomer · ‎03-19-2021

Hi Jan,

If 802.11r (FT roaming) is not supported, roaming will still happen but it will not be seamless like it will be when 802.11r is enabled.

Device should still work, connect and roam.
