Pre RS Errors Post RS Errors

Hello,

I am using Hub5 and noticed my internet connection struggles from from to time.

After initial investigation on router network status noticed Pre RS Errors Post RS Errors counts in Downstream channels, below is the log.

Can someone let me know is this the reason the internet connection struggles from time to time or its something else.

    How exactly does it "struggle" ?  On ethernet cable connections as well as wifi ones ? Can you do this....

    _________________

    Switch the Hub off and unplug it from the mains supply for five minutes. Whilst it's off, do a quick check that all of your coax and ethernet cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Also check that the internal wiring is ok with no kinking or chaffing. When its light, check that all looks good with the outside cabling and wall box (no “staples, etc.,) piercing the cables. Then switch the Hub back on and leave ~5 minutes When all done, check back in the settings and ensure that the RS error counts and T3 errors have all reset to 0. Then check every hour or so to see if they start reappearing - they shouldn't. If they do (particularly the postRS and any T3 ones) you have a problem (noise) that only a Tech visit will sort.  Also check the Upstream QAM’s are all at 64

    If they reappear - post up 3 FULL sets of data onto here – 2 tables from the Downstream, 2 from the Upstream, & the Network Logs pages. Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you (you may need to click the "submit" button again). If character limits are “exceeded” - just do two posts
