I was using a Netgear DG824M wireless router until a few weeks ago when it stated having sync problems. I then tried changing filters, Ethernet cables, using only the master socket and all the normal things. I thought that it was a faulty router so I bought a D-Link DSL G624M. This will not sync either. I called BT who came and checked my phone lines and they are fine. I only lose 1dB going to my upstairs socket which the router is connected to. I borrowed an old Alcatel Speedtouch USB modem from a friend and this syncs straight away and connects to the internet fine. Does anyone know why a router will not connect but a USB modem will?
