Guys got a phonecall from my Gran this morning saying her home computer wasnt getting any internet access so being the wondeful grandson I am I called up to try and sort the problem, but I am stumped now as to whats wrong 
It was all working fine yesterday, until this morning when she went to check her emails. The laptop works fine and can get the internet easily through the wireless.
I can only seem to narrow it down to a problem with the computer itself, I've checked the ethernet cable by connecting the laptop to it and it receives signals just fine. I've since brought the PC back to my house and plugged it into our network and its still not connecting. On the network map it just shows "PC - - - - - Unidentified Network - - X - - Internet"
Any ideas what I could do to try and fix it? Its a just a standard PC which you would pick up in a typical PC retailer on the high street nothing special and both routers are from Sky
Any thoughts appreciated
