Help? Realtek RTL8187B network Adapter

Hi All
First time posting on this forum so bear with....

I have a Toshiba Satellite L300D 11V
Also have virgin media netgear wireless router.
Up until recently I have been wireless and happy with my laptop without issues.
In the last week I re instakked Windows Vista onto my laptop and for the life of me I cant connect wirelessly.
I have tried the following...
Uninstalling the drivers, up dating the drivers form a variety of sources, windows, net etc
I can connect to the router via LAN cable but when I try to connect wirelessly no networks are available. The divece itself is working properly via Device Manger. I have used a friend's laptop and connected to my network fine and my phone also finds the network.
The diagnostic formulation always says both these, the network adapter is experiencing either hardware or driver issues,
or
protocols IE4 & IE6 are not installed..... When I check in device properties, all seems fine...
Im guessing this is somethig very simple and Im just thick...?
Cheers
