    Default wireless loses connection after few seconds

    I have a problem with my wireless card. At some wireless it is connecting but few seconds after getting ip it seems like disconnects. It is keeping the ip, i mean when i type ifconfig i see the same ip, but i cannot even ping gateway and of course i do not have internet. For the first 8-12 seconds is working, i can open pages, ping hosts, do everything normally but after this short period of time it seems down. And it has nothing to do with signal strength. I had the same problem when the access point was 0,5m. away.
    I have tried anything. This problem showed after bt4 pre. At this distro (bt4 pre) it was working perfect. But at bt4, bt4 r1, bt4 r2, bt5 the problem remains. I have tried 3 wireless cards, one of them was awus036h and 2 pc's. I have the same problem either if i run it from live cd, installed on disk or VMWare.

    I am desperate, any suggestion? I wander if anybody else faces the same problem, I have searched the forum many times but i did not find anything useful. And because i thing that this is a bug that's why i open a new thread here.

    Thanks for your time and sorry for my English...

    Maybe it's not a Backtrack or Wireless card issue, have you tried messing with the AP ? Turn off it's encryption or MAC filtering and check.

    I know it sounds like to simple of a fix, and there isn't a whole lot of people here with less experience than myself, but have you tried setting up static IP in wicd? I was having really bad stability problems with my MSI Wind u100 with an rtl8187se wireless card until I gave it a static IP and gave it the IP address to my default gateway. It was saying I was connected to my network, but wouldn't load Google, or even the router's configuration page. I setup static routes and not it works perfectly. Don't have much faith in it, but its too simple of a fix not to try.

    I'm having the same problems with a 'Intel WIFI Link 5100' wicd doesn't hold a connection very long.

    On Backtrack 4 Final it was working fine with the provided iwlagn driver but packet injection was not working. But now packet injection is working fine (a little bit buggy) on Backtrack 5 but just doesn't keep the connection active in wicd for very long (anywhere between 10 - 60 seconds).

    I did notice that it did hold a connection for longer if i was pinging an address (bbc.co.uk).

    I don't have any problems with it dropping a connection using any pen testing tools, only when trying to use wicd.

    This only happens to me on 2wire routers. anything under 80 percent and I lose connectivity after I open a page or do a wget. It gives me one page or reqrest then dies prompty.rebooting the router sometimes fixed the issue. its happened on about 15 2wire routers and happened on bt4 as well. I think its a wicd problem.
