Very, very slow VPN at busy times

I have  350mbps connection and speeds are generally good at most times. I have been using Nordvpn for a while. but for the last couple of months the vpn connection during office hours is dire and runs at about 10% of the norm and then returns in the evening.

Nordvpn has checked out all my settings and can find nothing wrong, so I can only assume that VM are somehow throttling my vpn connection.

Unfortunately it is impossible to get hold of a human at VM to talk this through and check my system and connections - anyone have a similar problem or any ideas?

Re: Very, very slow VPN at busy times

Hub Stats:
Open http://192.168.0.1/ or http://192.168.100.1/ (if you have your Hub in Modem mode) in your browser

For Hubs 2 & 3 - DO NOT LOG IN, just click “Check Router Status”

For Hub 4 - When the page appears LOG IN then click on: Advanced Settings > Tools > Network Status.

Please copy and paste the contents of the Downstream, Upstream, Configuration and Network Log tabs in replies here.

If this is your first time you may have to do first setup of hub password.

If I've helped please let me know 🙂 Matt

Re: Very, very slow VPN at busy times

OK those look fine.

Next can you try setting up a BQM - Broadband Quality Monitor

To do this first register here https://www.thinkbroadband.com/register , Once register go here https://www.thinkbroadband.com/broadband/monitoring/quality

Click on Create a new monitor, Enter a name for your Graph then Enter your IP address (this should already have detected your IP for you)

Select Cable Broadband as Type, Then enter postcode (optional), Allow in trends (optional)

Then Create

Then find your BQM here https://www.thinkbroadband.com/broadband/monitoring/quality/list

Click on Share Live Graph, then right click in the direct link box, click select all, right click again and copy into a reply.

 

 

If I've helped please let me know 🙂 Matt

Re: Very, very slow VPN at busy times

Good morning Matt,

So as normal the speeds this morning have dropped off:

7.00am 284mbps

8.00am 248mbps

9.00am 38mbps

9.30am 39mbps

This is typical of every weekday and can't be settings on my PC surely?

Roger
