I am new to the use of wireless systems. I have a WRT54G router and have been using it for about 6 months. About 4 days ago I lost my connection to broadband (ntl) via the router, I am now connected directly via cable to the STB. Every time I try to reconnect through the router I lose my internet connection. I have been advised to clone the MAC address? I have no idea how to do this can someone help???
