hi, guys. been looking at mates router which had unsecured wireless. put in wireless security and now cannot get internet access with either wired or wireless clients. all are connecting to the network but NOT the internet. a browse on linksys website found this: some cable providers require the MAC address of the connected pc to be cloned into the router. is this true of Virgin Media broadband? i've seen this in the routers setup pages but never come across or had to use it before.thx in advance.
