Hi all,

I've been having persistent internet issues for the past month+ or so, although today has been noticeably worse than usual to the point that it's becoming unusable!

During this time and on a mixture of both wired and wireless devices, I've suffered from regular internet drop-outs during browsing, on a video call or when WFH etc. I've been unable to stream (YouTube, Netflix etc) without suffering issues and buffering. I've also experienced excessive lag/ high ping spikes when playing online gaming to the point that it's a pointless exercise and after living with the above for some time now, I'm at the point whereby this really needs resolving.

I've provided some information from my router (Hub3) which I believe is often requested, although please let me know if there's anything missing:

Doesnt look good.

Can you Check for any “known network faults first - Try in 2 places

1) Try the “check service,”Area status webpage" (link at top right of this forum)

2) Then also try the “free & automated” Service Status number - 0800 561 0061 - which usually gives the most up to date info. and tells you of more local issues down to street cab/ postcode level.

If nothing shows try 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, 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 T3 ones) you have a problem (noise) that only a Tech visit will sort.
Also see if the QAM's are still at 32 - they ought to be at 64 and as your Upstream QAM’s are "dropping", see message 3 here…

Hi CrystalH, 

Thanks for taking the time to contact us via the Community. It's lovely having you on board with us in the Forums. ⭐

We're sorry to hear you're having an issue with your internet connection. 

Taking a look at things here, I can see there was an open fault affecting you. This has since been resolved so please reboot the hub to clear things and let us know if you're still having an issue. 

Thanks,
