no internet on laptop-help

gubby

I have wireless broadband on my laptop for years. Suddenly last night it just will not connect. says no network available. The internet is working fine on the computer in the other room. I didnt do anything. I was actually online when it went off. I have tried "system restore" (that usually works when it has happened before)
Can anyone help me please.. its really bugging me and dont know what else I can do??? :(
forgive if I have posted this in the wrong place.

Don't know what you've been doing, but the drivers might not be installed anymore. Check your laptop's manufacturer's site (look for a "Support" link) and download the drivers for your model. Install the wireless drivers and see if that helps.

Or post your make/model here and someone will probably get them for you.

Check your windows updates history, see if a driver for your wireless was updated.
See if you can roll it back

do you have a button on the laptop for turning the wireless card on and off like Dell ones usually on the side?
