Network Log Critical Errors - Hub 3

Hi,

I am a Newbie - just joined today because I am noticing some critical errors in my hub 3 Network Log as copied below.

Should I be concerned about these, and do I need to take any action?

Re: Network Log Critical Errors - Hub 3

T3 timeouts are not good, the other do not really matter. Go into your hub on 192.168.0.1 and post your up/down stream stats.

Re: Network Log Critical Errors - Hub 3

The odd T3 error every few days is of no real concern as the Hub and CMTS communicate every 30secs.
T3s in short succession will usually indicate a problem.

Re: Network Log Critical Errors - Hub 3

Hi Little_auk,

Welcome to the forums, I am sorry to see you have been having trouble with your connection. 

I have taken a look and it seems you are affected by fault ref F006938495 for SNR and FECS. The current review date is 06 MAR 2019

Please give this thread a bump closer to the time and we will get an update for you. 

All the best

Emma
