Alright, let me get you some beter intel on the AES fix;
First of all, im using wireless channel 9, 40mhz band. And its a Comtrend Multi-DSL vDSL modem (wireless-g and wireless-n).

WPA2-PSK AES:
Connection stable and up to speed. once in a while i get the 1mbit bug. Hit the Wifi button on the notebook, and reconnect.. fixed!. Happens once a day or so. PC idleness seems to trigger it.

WPA2-PSK TKIP:
Instant 1mbit cap on download. Upload is fine though (up to 5mbit here).

Alright, it is not a real fix.. but it should give a hint on the correlation between encryption and the bug. The point is, my WiFi is fine with AES (20mbit down).. and total garbage with TKIP. The AES requires a WiFi restart every once in a while though.
