Currently on VM 500 broadband and when sitting in the same room as the router get 200 on wifi. Over the last 10 days or so this has dropped to 60 or 70. I have not changed anything - not messed with settings or added any new devices - so aside from a router reboot my limited tech knowledge leaves me unsure what might be best to try next.

A quick Google suggests a number of things but is there an order of what I should try first?
Should I first do a ping test? Should I try changing the channel and if so how do I decide on what to?

I am running the VM Hub 4 in modem mode and using an Asus RT-AX82u 5400 as a router.

I would try to see whether it's a broadband problem or a wifi problem,
As my broadband is never that fast, I would simply connect to the broadband modem with a cable and do a speed test.

IF the problem is wifi side, then do you get the same speed with other devices?

Do a channel scan, are there rival networks affecting yours?
cycling the power may prompt the router to pick another channel.

Test 1 - Connect with a cable and run a speedtest.

If that is slow, contact virgin.

If that is fast then you need to look at what other wireless networks are around and alter your wifi channel to be a better one most likely.

Note - VM routers are known to be rubbish.

My router gives you the option to connect to either 2.4Ghz or 5Ghz - look at the label on the back of the router to see if there are two separate WiFi networks available for each.

Thank you. I heard that as well so went for the Asus router which seemed to get good write ups.

VM4 hub is crap, that ASUS router looks the business tho...

Make sure you are on the 5GHz band first, mine gives 2 connections so its "name_2Ghz" and "name_5ghz"

Get a laptop hooked in to the ASUS and do some speed tests through that to see what your speed is https://www.speedtest.net/

If that looks good get an analyser tool installed on phone and see what networks are around and what channels - I use this one https://play.google.com/store/apps/details?id=abde...

You could then think about swapping the channel if someone else near you is already broadcasting on the same as they can interfere with each other

As others have said, restart everything, including your device, make sure its connecting on 5ghz first, if its still slow, then try connecting with an Ethernet cable.

When I had Virgin, it wasn’t unusual for a 100mbps connection to get down to 2mbps with a 10 second ping during peak hours on Ethernet. I’d call and complain and they would reduce my monthly payment by 90%. Even when it was working well, peak hours used to see download figures running about half of the advertised speed.

Virgin were definitely getting the customers first and fixing the capacity later. Wouldn’t get Virgin again unless they were the only option in the area.

Not sure if its coincidence, but a similar thing happened twice to me now, when Liberty Global took over the respective businesses. Both my Virgin cable connection and O2 mobile phone connection went from good to bad within a few months.

On O2 their tariffs became really cheap and the phone service went to pot. They seem to go for market share over everything else. Dread that name now.
