I have a Dell 530 with a wired connection to a BT Home Hub. A few days ago the internet connection failed. The Hub and cables are OK as I can access the internet by wired or wirelsss connection using a laptop. Thinking the network card may have failed I have installed a new one. Device Manager tells me the new card is working correctly and the driver is up to date but when I try to re-establish the network connection the installation programme gets as far as testing the connection and reports 'not connected'. I know the cable is OK and the Hub is working correctly so cannot understand why the computer will not connect to the hub.
I have exactly the same problem - internet connection failed and when it restarted the wired desktop will no longer connect (though laptops will, even with the same cable from the back of the PC). I also tried putting a wifi dongle in the desktop to see if I could connect wireless and even that doesn't work.
I'll try the Winsock suggestion.
Is there any chance that the BomeHub software has been changed and some firewall settings have changed?
