>Description:
              I related this as part of kern/88882 and said that setting roaming manual solved it but that is not correct.

when I ssh to another machine and untar the ports tree with tar zxvf or get other fast text response almost imediatly the connection stop tx/rx

I set ndis debug but I get nothing 

ifconfig tells associated 

I can get the connection back by issuing ifconfig ndis0 ssid _MYSSID_ or any other ifconfig ndis0 command

I switched any other AP off so no chance that it associates to another.

I tried another PC to see if it is a problem on my NB but I get the same problem

Any other transfer as file download at high speed 100-200Kbit/s and over 50MB does not cause this, only text response cause the freeze.
