Hi I wonder if anyone can help. I have two computers and I am using wireless broadband (sky). Everything has been working perfectly ok, I have had it working for about six months. Yesterday the broadband on the upstairs computer went off. When you click on the little computer network icon at the bottom it says connected and strength excellent. When I try to refresh the connection I get the message windows could not finsih repairing the problem because the folllowing action cannot be completed, registering with DNS. When I look at the network connections box it says windows can not configure this wireless connection. Everything is running as usual on the downstairs computer. Any help Please.
