Hi. I've got a Dell D620 Latitude laptop.
Lately it's been loosing it's wireless adapter. Not the connection, basically the machine thinks it doesn't have any network capabiliy at all.
Try disabling the adapter and it locks up (although sometimes you can right click the windows wireless icon and repair, and it will come back).
So it's a hard reset, sign in to safe mode and delete the wireless adapter. Then when it comes back it reloads the drivers, I set up my wireless connection again and off it goes for another day or so.
I've tried updating the Dell wireless drivers, and have now loaded the intel proset/wireless software and drivers.
Any ideas?? Anyone?
