Yeah - I continued my original thread. It is odd though - a steady decline. You can't leak broadband
The odd thing was the second reboot - noise margin hit 19, then dropped immediately. The extension up here doesn't use Cat 5e - just generic telephone cabling (3 pair, twisted), which should be pretty much the same (the twisting is the main bit). But when I first got the router, no fancy faceplates, it was on the same wiring, with a Sky filter - I did notice the odd dropped connection, but never when I was using the PC. The dropped connections tended to be when I was away from the PC - I knew the connection had been lost because there'd be a message from BOINC, complaining about the connection. Mossywell logs confirmed it.
