Comment (by Jan-openwrt-trac@…):
It also worked for me in Attitude Adjustment 12.09. Problems started when
updating to Barrier Breaker 14.07 final. Same problem still exists in
trunk/Chaos Calmer. Happens in both 2.4 and 5Ghz. Roaming still works when
problem occurs.
When the problems occur I can see periodic ARP requests from to phone
asking for the MAC of the gateway (which is also DNS server). The gateway
responds but the phone seems to miss the response. Phone recovers after a
few minutes or when i restart the wireless at the phone. When the phone
recovers I noticed the rate at the AP to drop to 1MBit/s. May be the phone
goes to powersave mode but the AP still uses a high rate to send packets?
