3 unleashed R310, client stickiness

[jan_willem_henn]

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

Regarding smartroam (802.11v) if enabled, whena device is kicked and is not able to find a stronger AP, will it reconnect to the first AP again?

and when will it then be released again?

reason is for coverage in my garden.

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?

Can you send the commands used. i have 5 scattered around the house, R510 and one R610 and also outside one. Constantly have missed areas and drop calls and signals and sticky client even after putty use and changes done as suggested by few.
