I have just purchased a Belkin F5d7230uk4 router which I am using with a Virgin 2meg service.
I had trouble getting the wireless to work but I read on a site like this to disable the security and then disable the WCZ system as it was interfering with my Intel network card.
Duly did this and the wireless worked for the first time. I then went back in to set the secuity up and no matter which security I try to set up there is no wirless connection when it is running. If I disable it then it works fine.
