I have Windows XP home edition. Overnight I have problems opening windows explorer. I have three computers connected to the one rooter. Only the one computer (all the sudden) will not connect to the internet. 1. I first changed and swapped around network cables, that did not work. 2. I installed a new Network card, still does not work (DEVICE manager says the device is working properly). I have uninstalled it and installed it. 3. I removed the network card and put it back, still nothing. 3. I have obviously switched off the rooter and on again, nothing. 4. I have repaired the connection, nothing. 5. I have released and renewed IP configs in cmd, nothing. 5. It says the Local Area Connection is connected. 6. Diagnose connection problems: error "could not make a http connection", "could not make an https connection", "could not make an FTP connection". Please can someone help.
