umm well for about 6 months now i've had my laptop (with vista premium 32 bit) and i was connected wirelessly to my home network with no problems. Then all of a sudden a few days ago (13th or 14th to be precise) at midnight i no longer had any internet connectivity. I was browsing the internet, watching a video, from a little before midnight till 12:30 and when i was done i noticed the loss of internet connection.
When i try to troubleshoot the problem i get the "cannot communicate with primary DNS server".
I CAN access my home network (sent a file to our desktop computer's shared folder and recieved it just fine) but my internet connection is down. When i check in Network and Sharing Center i see the line from my PC to the home network in green but the one from home to internet is Xed.
On the other hand, my brother (who also has vista on his laptop) did not get this problem and any other periferal accessing the router (wii, xbox360, DS) can all access the internet.
I HAVE checked on the internet for resolutions to my problem, but they were all fruitless. My IP IS in the same range as my router, my default gateway and DNS server are the IP from the router and of course the subnet has the right configuration.
On the other hand, when i bring my laptop to school (which has wireless internet of course) my laptop can connect to it without a hitch.
My guess is that the problem may be a vista update (seeing as how the problem started at midnight... and i believe the updates are set to start at midnight)
On the other hand, i doubt the problem is a virus or anything like it because i did a system restore the day after i noticed the problem. The restore was set to the day before the problem occured. Needless to say the problem wasnt resolved.
I would be very grateful to anyone who could help me XD and thank you in advance to anyone who tries.
edit: oh and by the way im running on a dell Inspiron 1720... my brother (who CAN get internet with vista) is running on an HP.
