I'm having a propbolem with a Compaq N620C notebook. the wireless card it has will either cause a memory dump if it picks up a wireless router. or will not connect at all. and sometimes doesnt even pick up the router. after placing another wireless in card i still have the same probolems but i do connect,it just it tries to validate something and wont finish doing so. the laptop now just freeses every five minutes completely. (the mouse wont even work) i have to turn it off manualy with the switch.

i run my computer on Windows Xp 2000 home edition.

Try uninstalling the adapter, restarting the computer & installing the latest drivers for your adapter.
