Hello -
just upgraded to wireless-tools 28 just in case, but the problem persists.
Computer cannot connect even in the same room as the access point, when it
gets about 2 metres away from it...
to (slightly) increase link quality I turned diversity off
/proc/sys/dev/wifi0/diversity is set to "0"
/proc/sys/dev/wifi0/txantenna is set to "1"
/proc/sys/dev/wifi0/rxantenna is set to "1"
athstats output:
