Dell Inspirion 6000 Laptop - Windows XP.
The Laptop has had a working wireless with the same router, with the same WEP key, for a good long time without any changes. At some unknown date it stop working. It connects the the router, gets an IP address from the Router. But after that there is no more communication between the laptop and the router over the wireless connection.
I cannot ping the router from the wireless card. Yet I've gotten an IP address from it. Yet if I release the IP address, and then try to renew it, I do not get an IP address.
I have confirmed that the WEP key has not changed, and I have even gone so far as totally removing encryption all together. And yet to no help.
I have tried numerous possible solutions, on the internet, looking for possible bad windows updates, resesting winsock, even doing an entire reinstall on the computer, yet the Wireless internet is not working.
The Laptop when wired works fine, their is also two other laptops, another Windows XP and a Unbuntu Laptop that connect and function properly on the wireless network without fault.
I've entirely run out of ideas, other than suspecting it could be a hardware problem. The Router itself, while showing no real faults is an old Dlink DI-524 and it has the latest firmware for it I can find V 1.23
If anyone has any information or things I may have missed in checking, please ask.
