Help getting wireless internet setup

[jaysus]

My PC has a knackered display, so I bought a netbook (with wireless capabilities) so I can get proper internet rather than trying to use my phone.

I had a netgear wireless router in the loft that I'd never used. I got it out, connected it to my (Virgin) modem. It initially showed up, but long story short before I connected it the router stopped showing up on the list. I've tried rebooting both router and modem with no joy. The light for 'internet' shows a solid green light but the 'wireless' icon is unlit.

I've no prior experience of wireless networking, and I'm out of ideas. Anyone able to help?

Is there any other way of doing it? I've rebooted the router a few times with no success, and I can't find a spare ethernet cable to connect the router to the netbook.

Ignore my last, found a spare ethernet cable. Will give the above a go.
