My new Gig1 Fibre Broadband account started on 24/10/2020 but i am only getting download speeds of 200Mbps even on a Cat 8 ethernet cable. Also the engineer did not check for blackspots in the house and did not leave me any wifi expanders. I tried to sort this out yesterday but Virgin asked me to ring technical support. I tried three times but the number kept hanging up. I tried the next day and waited for 45 minutes on the phone with no answer. I have tried using the "Message Us" function and have waited for 5h for a response today. I am an NHS worker and need fast broadband speeds for work purposes.
Your Surface Pro is very capable of using anything that the Hub 4 can deliver.
As for the LAN speed on ethernet cable, the Hub 4 seems to deliver random speeds depending whether it is a cloudy day or complete sunshine.
The problem with Wi-Fi is that it can be brilliant at breakfast time and useless by lunchtime and you haven't changed anything, BUT, something, somewhere has changed, then you can spend hours and even days trying to find a fix for something that can be totally out of your control.
If you remove all the internal walls, water, electronic and electrical devices, metallic pipes and conduits and wrap the whole building in a thick lead shield you will have a good chance of getting decent Wi-Fi from an ISP Hub.
Just a few things that can affect Wi-Fi in the average home …
Mirrors, furniture, fish tanks, people, radiators, walls (some more than others), cordless phones, baby monitors, microwave ovens, fridges & freezers, TVs, next doors Wi-Fi and Wi-Fi equipment, DAB transmitters, the list is endless.
Many people have accepted that the VM Wi-Fi is poor and have purchased third party equipment that is much, much more powerful than the VM supplied kit and once set up have wondered why they waited for so long.
