Hello, everyone!

I've searched on TMO this problem, but anything that i tried did not helped me.

My N9 connecting to WPA2 PSK network, after 3-5 minutes latency gets to 1k-2k ms, after that i can't ping any site nor n9 from another device (notebook, desktop, etc). Wi-Fi connection still live, but traffic isn't send.

I've tried to turn off power saving on wlan0 interface (iwconfig power off), to disable power saving in N9 settings, use wpa2 only in wifi connection properties on N9 (if use wpa2 only, wi-fi connection returns error and can't connect).

Also, i've tried to configure my routers. Tried to use WPA2 AES, TKIP, no effect. Tried new firmwares on routers, change channels.

Tested on several brands - Mikrotik RB951, D-Link DIR-300, D-Link DI-824, Ubiquiti UniFi, Cisco 1941W.

If I turn off WPA2 on any of these routers Wi-Fi on N9 works perfectly.

I have N900 and it works perfectly on routers listed above. I've tried Sony Xperia S, Motorola Moto X, Lenovo P760 they works with WPA2 perfectly aswell.

Help me to resolve this problem, please.

My phone is Nokia N9 Meego 1.2 PR1.3 (40.2012.21-3_PR_001).

Thank you and sorry for my english.
