Hi, thanks for the help. I have posted my router line stats below.
I have already tested the router at the main BT socket. I took off the face plate and connected directly to the internal test socket and then to my laptop and there is no problem. I have replaced one of the adsl filters as I had one spare, but need to get another to replace the one on the Sky box and to rule that out from being faulty.
I have a cordless set of three phones, a usb fax, a truecall unit and a sky box connected to two separate phone sockets, both via adsl filters. I have two computers hard wired to the router and my blu ray player is also connected to the router.
Since the problem started on Friday morning, the intermittent connection continued on and off every few minutes until Saturday morning, when suddenly it resolved by itself and the connection has been up since then!
The exact same problem occurred almost exactly a month ago, lasted for about 24 hours and then resolved itself ....... all very strange!
