Ive been having an issue since i rolled out our new MR Wi-Fi. it seems that Samsung android devices connected to our Wi-Fi will frequently re-negotiate with surrounding APs. We have a fairly dense environment since we are a school that supports BYOD, so ive placed a lot of APs around the building and turned the power levels down. When i contacted support i was recommended to lower the maximum bit-rate from 54mpbs to something lower, but since these are somewhat new devices (less than 1 year old) that logic didn't make sense to me. Anybody else seeing this? All other devices are just fine with no roaming or battery issues.
. . . , so ive placed a lot of APs around the building and turned the power levels down.. . .
If you have a lot of devices in a compact environment with plentiful APs, you may be able to turn off the 2.4 GHz radios so that everybody uses the 5 GHz band.
If you must use 2.4 GHz channels, only activate them on about 25 % of the APs.
I have setup our 2.4 so there is no overlapping zones, that being said the devices that ive been testing with rarely connect to 2.4.
Mention of 54 Mbps makes me wonder if support imagines that there are 802.11g users? Might be worth clarifying.
