Because I am pretty consistently getting around 280-290Mbps.  That's pretty fast and probably as fast as I need, but I was recently upsold the M500 package and it's really not going to be worth it for me if it's only slightly faster than what I was getting before.

[Andrew-G]

On a 500 Mbps contract with a line that's working properly you should see a consistent speed around 530-548 Mbps (VM's expected speed range of 516-548 is usually pessimistic).  You'll see those on a device connected via ethernet cable, on a wireless device things are a bit more complicated.  For a high end wifi device close to the hub, connected to the 5 GHz band, you might get the full speed, although you'd probably need to check the 5 GHz channel width is set to 20/40/80.  For many wifi devices they'll top out around 300 Mbps in real world situations.

This is on a desktop computer that is connected by an ethernet cable to the Virgin Hub 3.0.  It looks like I'm not getting the benefit of an M500 connection for some reason.

[Andrew-G]

Connect to the hub by clicking on this link http://192.168.0.1/  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.

There's a fair few PostRS Errors.

When was the hub last rebooted? (Are they historic)

[MatthewBest]

My daughter has an unhappy habit of reaching out with her feet and accidentally switching off the router at the plugboard, so it has been rebooted fairly recently.  And it was of course rebooted when Virgin managed to persuade me to "upgrade" to M500 three weeks ago.

I can always reboot again, if that will make a difference, of course.

[lotharmat]

It's generally accepted that you need to power the hub off at the wall for 5 mins to ensure that the errors are properly cleared.

It would be worth doing that just to rule out a noise problem.

Also - look at the config tabs of the router status - see if the speed increase has manifested in the 'profile'
