Assess my connection please..

I need someone to assess the numbers from my "Router Status" pages please.
To check if there is anything that stands out.
This query relates to average latency and jitter when gaming.

Here they are:.

Re: Assess my connection please..

The power levels and SNR are fine, and no errors in the counters either. The network logs would have been useful. The BQM graph will be useful when propogated. (I would leave it 24hrs to get a full day's picture)

Are you connecting wired or wirelessly?

Wired through CAT6 into the SuperHubAC2 in Modem Mode.

I will post the Broadband Quality Monitor graphs and the Network Log once i have left it for 24hours without me tinkering Smiley Happy

Re: Assess my connection please..

All your stats look very good, including your BQM.

A couple of red dots of packet loss on the BQM but nothing to worry about.

Re: Assess my connection please..

Why am i getting 3mb~ download speed? And absolutely horrendous latency? [Wednesday 8.30pm]

(Yes the testing pc is wired to the superhub in modem mode.)

Here is a set of Thinkbroadband Speedtest results from this evening... (and the latency figures were through the roof)...  Smiley Sad

I see your package is 50/3.

Your BQM graph has a lot of blue spikes during peak time, 6pm-midnight. That's usually an indication of the user downloading/uploading a lot. Do you have anything running in the background?

48b27ea08ac44860668ac8d812f73cec

 

Normally if it was an issue of high utilisation on your cable (other people using all the bandwidth) then I'd expect to see very low Down TBB x 1 figures (left column), but they often match or exceed the speeds shown in the TBB x 6 column.

As I don't have your actual links, except the one you posted, I can't see the detail but that alone makes me question the cause.

Are your power levels changing significantly from what you posted above?

Can you post your network log as already requested? That might indicate a cause.

Does a reboot improve speeds for a time? Don't reboot until after posting the log.

 

As it's been a few days, we can get @Ralph_R or someone else from the VM Forum Team to check their end and see if there's an issue with Upstream SNR, or high utilisation during peak time?

Re: Assess my connection please..

This evening, the same thing happening as last evening.

I am going to just come out and say it right now, this IS a Virgin Media issue not household/user issue, and it is intrinsically tied to peak times.

User/household bandwidth useage Down/Up right now are absolutely minimal (in the Kb), i know because i am staring at a live (and historical) graph of the bandwidth down/up.

Superhub2ac in Modem mode. Rebooted fairly recently (24hrs~). [The reboot last night during the problem didn't change anything.]

Speed tests (including horrendous latency):

There is a small change in the Power Levels and RxMER(db) on Downstream when compared to the opening post.
There is a massive increase in the Pre/Post RS Error count.
The network log provides no useful information from what i can see, and nothing relating to tonights incident period.

Just look at the Broadband Quality Monitor graph...
Useage from the Household was absolutely minimal during that period. So I can guarantee you that is not being caused by excessive downloading or uploading because i personally monitor it.

Re: Assess my connection please..

Hi b4z,

Sorry to see you've been having connection issues, the stats and diagnostics are helpful thanks.

As you've already concluded by the looks of things, the problems are tied to very high peak time traffic on the downstream segment of your cable, this will be causing slow speeds and latency issues. Networks have this raised on ref. F003455769 with upgrades to add capacity now estimated for around August.

If you continue to bump us here periodically we'll gladly check with networks for any news or developments.

Apologies again for the inconvenience caused.

Rgds
