My internet was working well for some couple of days. I am using a Vista system. There are two Windows XP computers also on the network. Both are still working fine. After a few time the computer failed to receive any active connection from the modem. I am here talking about the Vista one. The machine has no changes but somehow the connectivity failed instantly. I tried to plug and unplug the router cable but still the problem remains intact. I am not able to figure out the issue behind that. It is a bit shocking to find that suddenly the settings was lost which was quiet working well before. I am bit annoyed with the same. Is there a way to fix the same. Thanks.
