I was running DSLstats on the laptop ( wireless ) while checking behind my PC , which was off but plugged in to a socket thats switched off. When I removed the ethernet cable from the back of the PC CRC errors shot up SNR margin dropped , so plugged it back in everything returns to normal . Then as an experiment unplug the PC from the power socket and that shows CRC errors but not as dramatic , could this be an earthing problem ? or my old reliable Billion 7800N cheers

I think you need to perform one further experiment . . . and that is to disconnect the Ethernet cable (which runs to the switched off PC) from the Billion 7800N.

What do you now see, reported by DSLstats?

and here is the result  :no: , didn't leave it out too long as not sure how far SNR and CRC's were going to go .it's the spot just before 6.31

To me, all the results seem to be indicating a problem with the Billion 7800N.  :-\
