[HELP] Wired connection slow but wireless fast? (550Mbps Wireless) & (130Mbps Wired)??!!

[Ripp]

My Virgin Media fiber connection has been a rock solid 550Mbps for nearly 1 year but for the last 3 days on my wired connection it's just 130Mbps. My phone still gets 550Mbps over a wireless connection (right next to the Hub).

I've tried both a desktop PC and a laptop with a wired connection and gotten near enough the same result so I can rule out my hardware so it must be a problem with the VM Hub's wired connection somewhere?

Any ideas?

Well my hub is giving a stable 550+Mbps over WiFi so it can't be an issue outside of my house, the hub is just having a problem kicking out the same speed over the wired connection even though it's been fine for 10 months. Hopefully the engineer visit on Friday will sort it. My guess is a problem with the hub.

And strangely my wifi hasn't been that problematic either...My iPhone 8 average (beside Hub) has been around 500 odds over past few months??? My last realsam download to hub/device results on my phone hourly were:  429/460...924/614...401/596...988/590...425/609... 393/485 (Upload always around 50). I wonder if realsam is actually the issue sometimes because if im getting e.g. 401 to the hub then how can i get 596 to the pc?

good question - i only have 200 speed but have a hub4 and my speed to the PC is always higher than my speed to the hub using the samknows test - i have just assumed there is actually some overhead in the reading shown to the hub or the test is rubbish - the speed to the hub may or may be of interest but only if the speed at the pc is low

samknows has been pretty rubbish for me also.

SOLVED! I turned out it was a problem my end. For whatever reason I had to reset my network adapter settings on my wired PC. The low speed results I was getting with the wired laptops must have just been a coincidence as they are old laptops.

For reference it's: Windows Start Menu/Settings/Network & Internet/Network Reset

Just to add for anyone else trying to diagnose exactly what part of a network is causing speed issues, it's worth buying an Ethernet to USB-C (or whatever USB your mobile phone has) for about £10 from the Rainforest. As it essentially turns your phone into a network speed meter.

I bought a USB-C 1Gbps one and I use the Ookla speed test app so now I can just plug it into any port or ethernet cable that's connected to the internet and it'll do a speed test. By process of elimination I can now narrow down what's at fault. If I'd have had that a week ago I would have avoided having to take a day off work and wait around for 4hrs for a VM engineer to come out.
