after purchacing a wireless Netgear modem/router I have a problem in that it will NOT connect to the internet. problem is the internet light stays red stating no connection. The item has been exchanged as faulty, but the new one gives the same details. I have checked the ADSL settings and all seems in order. the new router is the same make as my old hard wired one. which when i connect back together works perfectly any suggestions would be good
