High ping , jitter

[Bigbal]

When i signed up to virgin media a few years ago i consistently had ping speed of 10ms with zero packet loss. I also experienced excellent wi fi coverage all around the house. For the last few months im now getting ping speeds of 25ms and 10ms jitter. I cant stream anything on HD in the up stairs bedroom either has to be SD and im getting regular disconnects on whilst playing on xbox live. Iv tried all the usual resets and and stuff but doesnt fix the issue. Can someone help please?

Wifi coverage may be a separate issue to the latency issues.  Let's see how latency and packet loss are on your connection: Setup a BQM over at https://www.thinkbroadband.com/broadband/monitoring/quality that'll show what's going on with your VM connection.  Post a LINK to a LIVE, SHARED graph here and we'll see what's happening.  Usually needs to run for 24 hours before we can draw reasonable conclusions, but the live graph will continuously update so you can post the link immediately.

 Is this what you wanted me to do?

[Andrew-G]

Exactly that.  Early hours yet, but initial view is a very poor broadband connection, which can usually be resolved when the probable cause has been identified.  Getting that fixed will sort out most poor connection reliability issues, won't make a difference to wireless reach in the property, but worry about that in a bit.

As a next step, can you connect to the hub by clicking on this link http://192.168.0.1/  Or type that into a browser if the link into doesn't work.  That should pull up the log in page for the hub.  But don't log in, just click on the link "Check router status"  That'll bring up a window with five tabs.  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 and Network log.  You'll get an error message when you post the Network log, just click on "post" a second time.

Then we can check for any obvious problems with power, noise or error counts.

Unfortunately I can't spot any obvious problems in that data.  There's some issues in the network log, but they don't appear to be persistent, and other than that power and noise levels seemed good when data was taken.  The BQM shows the connection is intermittently poor, all I can suggest is waiting for the forum staff to advise.  Possibly they'll be able to see things that I'm not seeing.  

If you get a response "all looks good from our side" but the problem continues then you may need to be very persistent.to get this fixed.

[Bigbal]

ok, so is it just a case of waiting for someone to get in touch?

[Andrew-G]

Yep.  The forum is patrolled by VM staff, and they'll pick up your post and reply.  Sometimes quickly, sometimes takes a couple of days, as this isn't (from VM's side of the fence) first line support.
