Good evening, 

Recently I have been experiencing agonizing internet issues (even more so when it happens mid kill streak on Call Of Duty). I have been experiencing intermittent disconnection on all devices wired and unwired, rendering most tasks involving the internet painful at best.

I have checked all my coax wires to my Hub 3.0 and they are all tight, I have tried the pin dot reboot on my hub but to no avail. I have scouted other threads and learned I needed to check my hub for the network log, just not too internet savvy to understand what a lot of it is, so posting it here in hopes of someone shredding light on what could be causing my issues. (from observation from other threads it is the wiring from the cabinet to my house). 

I will post my downstream and upstream pages and extra info in the following few posts as I can not fit it all on here

If anyone could offer some more information on these errors I would be eternally grateful.

Many thanks,

Also I have set up a broadband quality monitor, and this is what it looks like in the past 24 hours (you can clearly see when I went to bed and have been at work all day haha)

If I can provide any more information please let me know.

[Andruser]

When was the hub last rebooted?  Asking because that sets error counts to zero.  And have you tried a pinhole reset?

The BQM shows some weird spikes, but for the most part is OK, but the network log confirms that you're having repeated dropouts.

[KennellyA]

The hub was switched off for 10 minutes either yesterday or the day before I can't quite remember which day I did this on apologies, and I have been having these issues for a few weeks and just put it down to increased traffic due to lockdowns etc, I tried the pinhole reset when I first experience problems not long before Christmas, I hope this helps

[KennellyA]

the dropouts have been extra bad today 😞 any suggestions on how to resolve this problem?

[Andruser]

I've flagged that for the forum staff to advise, as I'm out of ideas.  One thing we've seen before has been isolated wifi devices causing similar spikes, but I can't say whether that would apply for you.

[KennellyA]

Thank you for taking the time to read it all anyway and I appreciate your help, hopefully i can get to the bottom of what is causing this

Good morning @KennellyA 

Welcome to the forums and thank you for taking the time to post. 

I am sorry to hear that you have had some issues with drop outs. 

So that I can take a further look into this I am going to need to drop you a PM. 

Kind regards,

Zak_M
