Suddenly lost network connectivity - Vista, Acer Aspire M1610
Posted on 2008-10-07
Ive listed the PC make and model but Im pretty sure thats irrelevent.
I have a number of computers connected to my home network, all shapes and sizes.
My Vista Home Premium machine has inexplicably and suddenly just stopped connecting to the network. Could be (is likely to be) coincidence, the last thing I remember doing on it before I noticed the problem was backing it up.
On the network card there is a steady lamp which is what I expect, but there is no attempt whatsoever to contact the router's DCHP server to get an IP address. Consequently the second lamp (which usually flashes to indicate network traffic) is off.
When the machine is booted it now says that it has found an unidentified network. I believe this is because it cant (wont) connect to the DCHP server and is using the failsafe ipaddress instead.
I have tried manually setting the IPaddress on the card and the card settings appear to be normal. I have also done a full scan of the system for virus/spyware (AVG8) and it is clean.
Failling a complete format and start again - which I am on the verge of doing! Can anyone think of why this may have suddenly have started happening?
