Hi, I have a similar problem to the another message on the forum.
I have two computers, one will connect with wireless or network cable quite happily to my adsl router and internet (laptop with Vista).
My desktop XP will get an ip address from the router but I cannot ping it or anything else. My computer was working perfectly one second then suddently it lost internet connection. Since then I have not been able to connect to the internet.
I thought it might be the onboard network card so I connected a usb wireless and it still does not work.
I have turned off all firewalls, reset the tcp/ip stack (using netsh), uninstalled and resinstalled the network card.
Looking at other posts on other sites, I also upgraded the firmware on my router.
My DSL-G604T router lists the computer in it's list of assigned ip addreses (10.1.1.2).
I am about to go crazy trying to fix this...
Does anyone have any suggestions?
Thanks
Gunter
