Packet Loss and latency spikes again

November last year going in up till march-ish I had high latency spikes due to congestion. That eventually got resolved.

2 weeks ago I got a text message from VM mentioning essential network work was happening (and then another about it finishing).

Since then I've had ping spikes but not as bas as last time, but now also packet loss.

Area Reference: 20

Re: Packet Loss and latency spikes again

Can you post your Hub status and logs?
Someone should be spot if there is a problem
Navigate to http://192.168.0.1 (or http://192.168.100.1 - if in modem mode)
Don't log in!
Click on 'router status'
Copy/paste the data from each of the tabs as text into a 'REPLY' as opposed to 'QUICK REPLY'. The forum software will remove the MAC addresses for you (If you get an error - just click the 'post' button again).

Also, set up a 'Broadband Quality Monitor'. This will monitor the state of your connection and record any network dropouts etc - You can do this at ThinkBroadband (https://www.thinkbroadband.com/broadband/monitoring/quality)
Give it a while to gather data and then click 'Share Live graph' and paste the 'Direct Link' into the forum!

Re: Packet Loss and latency spikes again

Hi there @IssacKingsley 

 

Thank you so much for your post and I am so sorry to see that you have noticed these issues. 

 

I have checked your Hub and can see that everything is working in spec. 

 

Can I ask how things are looking since your last post? 

 

Thank you.

Re: Packet Loss and latency spikes again

Still some ping spikes and spots of packet loss throughout the day. It dropped completely during the night for 15 minutes or so

Re: Packet Loss and latency spikes again

It got worse again. This is the exact same thing as last year, usable during the day and latency for days during the evening. Playing online games is near impossible

Re: Packet Loss and latency spikes again

You have an upstream noise problem, evident in the data you posted earlier.  On a good connection, the upstream has 4 channels working at 64 QAM (in simple terms think of QAM as a data rate).  Your was showing two channels dropping to 32 QAM, and one to 16 QAM.  When the upstream goes to pot, it affects latency and reliability,  but often doesn't show up as an upload speed problem.  It is possible that when Ashleigh_C looked earlier the upstream was performing well because these faults are often intermittent, but they could perhaps have spotted the evidence in the data you posted.

If the problem continues and there's no area fault then you need a technician visit to fix it.

Re: Packet Loss and latency spikes again

Thanks for giving us some more information about the issues @IsaacKingsley.

 

There is a noise issue as @Andrew-G suggested in the last post, we will need to send out an engineer to resolve this.

I can book the appointment from here but would need to confirm a few details via a private message, that I will drop over in a moment.

Please look out for the private message and we can get started.

Regards,

Steven_L
