Re: Constant Disconnections
Telephone wire is always 4 or 6 core twisted pair so there is always wires hanging arround doing nothing but they only seem to cause problems when they are connected. I think they act like aerials picking up all manor of interference. Now reboot your router and keep a close eye on your CRC errors, they are the most likely cause of your instability. In an ideal world they shouldn't exceed 0.1% of the SF "Superframes" transmitted.
Previous 15 minutes time = 15 min 0 sec
SF = 52931
CRC = 114
LOS = 59
LOF = 0
ES = 5
So from above they shouldn't have exceeded 52, but that was only 7 minutes worth my guess is they were getting alot higher than that over a period of time.Last edited by Koala5; 06-09-07 at 11:54 PM.

Re: Constant Disconnections
My girlfriend tells me that the ADSL has been restarting over the day, but as I didn't have Mossywells application running at the time it wasn't rebooting the router.. meaning I have a nice big chunk of stats!

The CRC's do seem high, are the causes mainly internal?
