Wi-Fi connection via iwi(4) dies regularly

[martinko]

Hallo,

I'm trying to use my Intel 2200bg WiFi card to access the internet (via 
D-Link DIR-655 gateway) but it is very unreliable.
Usually within 1-3 hours connection dies and I have to restart it (I do 
it with /etc/rc.d/netif script).  Then it works for some time and dies 
again and thus cycle repeats. :-/

Is there something I can do to help someone debug and fix this issue 
please ?  Thanks!

With regards,

Martin
