      Suffered 24hr service outage - now reconnect at 25% lower speed

      During the middle of the week I was unable to connect to the internet for a period of about 24hrs - the modem seemed to synch at the usual speed of approx 11500kbs but I couldn't access any sort of webpage - the connection status on the modem would say 'Negotiation: LCP allowed to come up' but that's about as far it got (No authentication, IP address, etc).

      24 hrs or so later, service resumed but downstream connection speed had reduced by about 25% to 8458kbs and similarly upstream speed had reduced as well. Line attenuation was the same but SNR had nearly doubled to 12db

      I've logged a ticket which is apparently being passed to Tier 3 but wonder if anyone he might be able to explain what is happening...

      Re: Suffered 24hr service outage - now reconnect at 25% lower speed

      It looks like your line has been experiencing errors and you have been capped. You should check that the problem is not coming from your internal wiring by plugging into the test socket. Even with your present cap, you are still generating errors. Without stopping these there is little chance of getting the cap lifted, with your attenuation, they may even put you on G.DMT, which will restrict your speed even further.

      Look in the Cable and Faceplate section for more info on how to improve your wiring.
