I am running a laptop using XP. Internet and wifi were fine until yesterday but now, upon opening Firefox, I get:
Firefox can't find the server at......etc. I've tried a different URL, Google for instance.
A similar problem if I try IE.
I've switched the laptop wireless off and on, rebooted the router, even reset the router. The machine shows that I am connected to wifi with "excellent" reception.
Then I tried a direct connection with a LAN cable. still the same.
I ran the "repair wireless network connection" option but to no avail.
I disconnected wifi and retried connection by re-inputting the key but then it does not even connect.
If I then shut down the machine and reboot it picks up the wifi again just fine, but still no internet.
I uninstalled Firefox (including data), and rebooted. Tried again just with IE. Still the same issue.
I am running another laptop (Windows 7) which is fine on the same wifi. so is my iPad
