Post RS errors et al...

Hello all,

I have recently upgraded to M350 fibre broadband and as part of this upgrade was sent a new Hub3 to replace my old Hub2.

Whilst the broadband speed is very good, I have noticed a few glitches that seemed to affect online gaming more than anything - this is something that we never experienced prior to the upgrade.

Anyway, I have done a little trawling through these community pages and seem to have some similar issues to others in regard to Post RS errors and some spurious entries in the network log. See below.

For note, I have rebooted the Hub several times and each time, the errors are reset to zero before they build up over the period of around a week. The errors listed below are probably over the last 2 weeks or so.

Given the current pandemic we are all going through, I'm not expecting a visit from an engineer any time soon but if anyone has any other suggestions, then please let me know.

Thanks,
Carl.

Hello

As quite clearly shows these this could be down to noise on the line, go around and check that all coaxial connections to all VM equipment are finger tight and that there are no unterminated connections, once done power off the hub for 30 secs, and back on if the Post RS errors keep increasing at that rate you will need an engineer to resolve.

Re: Post RS errors et al...

Hi Mike,

Thank you for your quick response.

As suggested, I have rechecked the coax connections and all appear to be ok and tight.

Yesterday morning, I reset my router so the error counts would reset to zero. The latest logs are shown below.

I am concerned about the 'critical' and 'warning' error messages that are regularly appearing in the Network Log. Is this normal? or to be expected with the amount of errors I seem to be getting?

Thanks in advance.
