Area 24 Latency issue

Hi Guys

So over the past few weeks I've noticed that webpages will just stop loading and need to be refreshed to finish, it's been a minor annoyance but its been happening more and more frequently, and now its starting to cause issues (gf ended up double-paying for something - luckily the bank stopped it - and my Internet banking authentication fails, but works fine over 4G from my phone)

I've been running a Broadband Quality Monitor for the last day or so and that seems to show that the issue is frequent, but not consistent, latency. Router reboots don't seem to have an effect (I'll try later today and see if the graph changes)

My Broadband Ping - VM Connection 4/4/17Worth noting that for almost the entirety of this test I was at work or asleep, so these are happening independent of usage, and aside from some blips around 4:30pm there doesn't seem to be significant packet loss, but it's still highly disruptive (I can forget about gaming and most media streaming is out of the question, reducing my Vivid 152 Optical Fibre package to basic web browsing and some Youtube if I'm lucky.

Is this the Hertfordshire overutilisation fault mentioned in this thread, or something different?

Re: Area 24 Latency issue

Hello there Charax,

Thanks for joining the community Smiley Very Happy

Really sorry to see the problems with your connection, I appreciate the testing you've done so far. I've taken a look from our end and I don't see anything obviously wrong right now. Are you able to monitor the performance of your network with your Hub in Modem Mode?

Hope to hear back from you again soon,

Take care.

Re: Area 24 Latency issue

Hi Heather, thanks for responding!

I didn't put the router in Modem mode as it seems to be returning to a quasi-usable state, also seems to be a regional thing as another VM user a street over is experiencing exactly the same thing, if the issue recurs (or rather, worsens, the graph seems to indicate lag spikes are just going to be a fact of life for me now) then I will continue the diagnostics in modem mode
