I've noticed that in the device list of my AP there was a client with a low (IMHO) RSSI -84dBm. As soon as this AP was switched off the client moved to the other AP and it went to -74dBm not that great but better.
I read the following:
Quote </ Unless you use an Enterprise Grade WiFi system such as from Cisco/Aironet or Aruba, with managed APs, any other scheme will have the consumer-grade problems. As IEEE 802.11 does not require a client device to choose the best-signal (strongest for which the client has decryption keys). So a client device (laptop, tablet, smartphone), will choose first-heard during a channel-scan. A scant few take the time to sit for 100mSec (the default beacon interval) on each channel. Few do, as it takes too much time and battery usage.
So non-Enterprise WiFi burdens the human user of the Client to choose best-AP if their device does not. /> Quote
is this true...?
