Poor Internet Performance in home

[Psiethyr]

I have gigabit internet to my home, however over both wifi and ethernet I'm getting about 120Mbps instead.

I have reset the router.
Restarted devices.
I have waited numerous days.
I have reinstalled ethernet drivers.

Everything. Still God awful performance.

What wired device have you tested with?

Could be limited to 90Mbps due to a 10/100 ethernet adapter.

Can you test like this...

If you think that you have a BB speed problem, then to check the speeds coming in to your Hub properly, and whether they match what you should be getting, You cannot rely on wifi tests, - only speeds "TO" the Hub and out on ethernet are usually guaranteed.
So, can you test speeds directly like this. If you expect >100Mbps then.... Connect a 1GB enabled computer/laptop (check network card is set to 1GB) , with up to date drivers, via a NEW and working Cat5e/6a ethernet cable, directly to the Hub which you have put into “modem mode” (https://www.virginmedia.com/help/virgin-media-hub-modem-mode ).

Or go into the Hub settings and turn off/disable the wifi and also disconnect all ethernet cables from the Hub, except your one device. This ensures that NO other devices are connected
Test speeds at https://speedtest.samknows.com/ - or https://www.speedtest.net/ - try on 2 different browsers - as Chrome sometimes gives odd results.

If they are still low – boot your device into Windows safe+networking mode - to disable any potentially interfering software - and try again.
There are many posts on here (I have a list of ~30!) where QoS software, anti-virus, unknown/flaky software, old network card drivers, corrupted browsers, bad cables or other connected devices are limiting speeds on tests.
Report back what that gets.

I've tested on my PC, I have a cat6 Ethernet adapter which can support gigabit speeds. 

I'm also not going out to buy another new ethernet cable when I already have a cat6 that should support this.

Not to mention that the issue persists even over wifi when I'm 5 feet away from the router.

Could you try the realspeed test in safe mode with networking, as suggested above:

If the issue was with a specific device I could understand why this would be a valid suggestion, but I experience it across two devices with two different connectivity issues, frankly I just want a damn engineer to come out and sort the issue for me because it's getting ridiculous.

Can I get some VM staff to reply and sort out an engineer to look at this?
