Ok,
By the advanced wireless menu deselected WLAN partition, WMM enable, Short GI and extra wireless protection.
I also turned off the firewall, wish Qos and Wifi protected setup. I do not run any mac filtering or what so-ever.
I use WPA2 encryption and I also tryed to see how it wroked while turned off.
The adapter I use is the DWA-140 USB dongle.
This is the configurition that the connection is at his most constant way, meaning that he will drop once in an hour.
For the wireless I have selected Channel 1, and set it at 20/40 mhz.
I use FW 1.12 (I also tryed different firmware versions)
Help is very very welcome
