Connection Problems - Very High Post RS Errors

I believe we have a problem with our connection. We are constantly disconnected from online gaming, videos stutter when playing back, and even web pages fail to load or take an age to resolve the address. I have checked the status of the SuperHub and found one channel, DS-3, has enormous levels of Post RS Errors.  856 Million since rebooting the Superhub last night.  The RxMER, 26.47, is much lower than all the other channels (35-37).

 

Do I have a problem with my Superhub or Line?

Service Status shows no problems in my area - Oldbury, West Mids

Re: Connection Problems - Very High Post RS Errors

Right, well your power levels both Upstream and Downstream are perfectly fine.  As you say, it's that DS-3 channel that's an issue with its very low Signal To Noise Ratio of only 26.47db .  I've never seen that before where one channel is so much lower than the others but I've no doubt some forum member(s) has.  I'm sure that rogue channel will be dragging performance down.  The threshold is 34.5db and the higher the better beyond that.  None of your channels is particularly high which suggests that you do have a rather noisy connection.

Check that the cable connections to the hub and wall socket are tight and if that is not the cause I think you had better arrange an engineer's visit with VM.

Really sorry to hear you've had trouble with your connection.

Re: Connection Problems - Very High Post RS Errors

HI,

 

Thank you for your input and suggestions.  Engineer attended on Thursday and confirmed too low SNR on channel DS-3.  He reterminated the connection into the house and I think changed the 'tap'? point in the cabinet.  A -10db attenuator to lower the downstream power level and now I have the following after two days of uptime:

Everything seems fine now.  Consistent speedtest results and no ping loss.

Great service by the engineer.  Thank again.
