Bet you're bored of all these Ping & Latency posts

Having similar issues to others, my ping & latency keeps spiking. I've been playing a lot of Modern Warfare and the packet loss symbol appears frequently. I might get 1 or 2 games that feel OK, it gets worse the more I play.

I 've had broadband for 7 weeks, through most of december it seemed fine, the past 3 weeks have been terrible though. I previously had sky and was fortunate enough to always have great latency (usually in the 20ms according to MW), never saw packet loss in anything.

I ran Resource Monitor last night and checked the packet loss in there while playing, it all seemed to be fine for the TCP connections so suspect it's UDP causing problems.

 

Here's some BQM graphs for the past 3 days, there's usually nothing happening between 12am and 7am, from 7AM onwards is when we start using things (home working, home learning, etc).

I've ran a few ping tests from the router to google & Virgin, these seem worrying.

So, does this look like contention/over-subscription issues, or does it look like a line or modem issue?

Also is it likely to improve things if I get a separate router and put the superhub 3 in modem mode?

Re: Bet you're bored of all these Ping & Latency posts

Sorry to bump, just wondering if anyone can confirm this is utilisation issues, or if it's something that could be fixed with getting a new router?

One of your upstream channels is out of spec (QAM) and your downstream power levels are either just under or over spec (In spec is -6 to +10, 0dB is optimal).

Re: Bet you're bored of all these Ping & Latency posts

Although @carl_pearce is spot on, getting that fixed probably won't change the symptoms you're experiencing, since any noise or power problem would still exist during the small hours of the morning when your BQM is "clean".

Re: Bet you're bored of all these Ping & Latency posts

...and just to add, buying your own router won't help one bit, nor will increasing your contracted connection speed.  What the BQM is showing is that at certain times of day there's high peaking latency between your hub and the BQM servers, very probably between the local coax circuit and the gear that sits at the head of the coax network.  All that the router side of your hub is doing to generate a BQM is responding to an incoming ping request, and your hub is doing that perfectly well, unfortunately there's a data traffic jam somewhere upstream.

Thanks for those answers, I'll save the £ and skip getting another router.
