I have a Windows XP desktop - wired to my Motorola router/modem from AT$T for a while. I been able to run a Vista Desktop and a Windows 7 Premium Home with no problem. I got the A V Guardonline spam ware. I was able to clean it up using Combo Fix and Malware Byte. After Combo Fix - at first I didn't an Internet connection. I had to go off. When I came back decided to check the Internet before I deleted the network driver. However, it turns out the Internet fine and I can still see and access my Vista computer on the network. However now the Windows XP Peer to Peer network doesn't see my Windows 7 laptop. The laptop and see the network and connect. However it can only see the vista desktop and not the Windows XP and even though it connects no Internet access. In network and sharing it shows unidentified network public. I think this should be set to HOME. How can I do this? I have Windows 7 Premium so I can't use secpol.msc. What to do? I have turned off all feature or services with the Home Group. My IP address is 169.254.141.68. I know that means I not getting a valid IP address. Also when I on Windows 7 laptop in network and sharing - I connect to my network - it sees it but then says it can't connect but when I check it is connected. It sending and receiving bytes but it can't ping or see the router.
