I work lates, so am mostly using the Internet when I get back home after work, around 00:00-04:00 but during this time 9/10 days my connection is so poor I cannot play most games on my PS4 due to lag and high ping. I check online and it says nothing is wrong with my service, which obviously isn't the case. Any ideas why this is the case, and what I can do? I pay for Virgin broadband to be able to use it 24hrs of the day, whenever, but for some reason it never works late.
Are you using a wired Ethernet connection from the PS4 to the VM hub or a wireless connection?
If you go to http://192.168.100.1/ to get the VM hub GUI. Don't login but instead click on Router Status which is either a button in the top right of the screen or a text link at the bottom of the screen depending on which hub you have. Click on the Downstream, Upstream and Network Log sections and copy & paste the figures from those screens and post them here. If you attach screen shots then they will not be visible to most of us until they are approved by a moderator so pasting text is better, don't worry about the formatting.
The community can have a look for you and see if anything in the figures looks wrong and advise accordingly. Or you can wait for the VM staff to pick up this thread in a few days and run checks on your line.
