Hi,

I connected my Gateway system to router through wireless adopter
It worked fine for some time
Once the system was shutdown suddenly (switch off)
After that I could not connect to network

I am getting the following error message when I click refresh network list
"Make sure the wireless switch on your computer is on"

Please let me any one can solve my problem

Thanks in advance

Is the computer a laptop with wireless (Toshiba?? ), then check in your manual you will see a reference to a wireless switch which you need to switch on again to access the wireless network.

Sounds like your router was damaged. Did you try resetting the router?
