Intermittent internet

Hi, I'm getting intermittent internet and alot of latency and packet loss when gaming. I've got a hub 3 and I'm connected via ethernet.  An engineer's been to the house and done some checks and said everythings fine although my internet is still really bad and online gaming just isn't doable at all. These are the issues I'm reading on the network log.

And above is an image of the broadband quality monitor.

I've tried speaking to customer service and I'm pretty sure I've been deliberately cut off twice and I've spent over 2 hours with another couple of advisors who just ignored any issues I raised about the network log. This has been ongoing for almost 6 months now getting gradually worse.

Re: Intermittent internet

Network log confirms that you have a very poor connection, but the first line call handlers don't appear to understand anything about the technology or network log.  You might as well try speaking to them in Martian.

However, the forum staff and regulars do have an understanding, so if you go back to the status page where you got the Network log, open the Downstream tab.  Select all the text (Ctrl-A if using a keyboard), copy it (Ctrl-C), then paste it (Ctrl-V) into a reply here as text not screenshots.  Post that, do the same for the Upstream.   Then we can check for any obvious problems with power, noise or error counts.

Re: Intermittent internet

Hi TA3, 

 

Thank you for posting to the Community. 

 

I am very sorry to hear of the issues you have been experiencing with the service.

 

I would like to take a look from our side but I am afraid I am having trouble locating your account from the Community details.

With this in mind, Ill pop you over a private message now and this will be available via the purple envelope on the top right of this page.

 

Speak soon, 

 

 

Nat

Re: Intermittent internet

Internet's been bad again today. It's getting so annoying. TV and works getting affected, aswell as gaming being unplayable.
