I have a Dell
Studio 1555 laptop with Windows 7 Home Premium 64bit that I've owned for just over two years.
Last night, after a couple of hours using the internet, the connection stopped. The wireless router still had an 'Excellent' signal, but it also said I had no internet access. All of the other wireless devices in my house connect to the internet perfectly, including when right next to the laptop.
I've tried disabling the firewall and resetting the computer a few times, but nothing seems to pick up the internet access. The troubleshooting guide tells me that it is a problem with the wireless modem, but quite obviously that isn't true.
I haven't installed anything on the computer for several months, and I have already ran a full virus check. Can anyone help me? Thank you in advance!
