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?
Solved! Go to Solution.
Ok, so I have experimented a lot and finally configured my 3 r310’s as follows:
still a little stickiness on some devices, so also enabled:
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?
802.11r & k can be helpful if you clients support them (the iPhone does) - it allows the connection to the new AP to be setup before losing the connection to the old AP so the transition is faster/seamless. This way as the client changes APs (and channels because each AP should have its own channel to minimize interference) it does the smallest drop in performance during the changeover.
I would suggest first assessing what the dBm of each AP reported by a WiFi scanner as you walk about on the second floor. If the values are very close (say within 20 dBm) between the 2nd floor and ground floor APs, then I would consider relocating the APs to minimize overlap.
Then I would experiment with either setting bss-minrate, say to 12 (which means disallow connections if the data rate is < 12) and/or smart-roam, which will deauthorize clients if another AP sees the client with a much stronger signal. You can do a web search for Ruckus articles on these settings.
