Problem connecting 6E laptop to WiFi

Had a new laptop, Christmas gift costing almost £1,000 Samsung Galaxy Book 3 but could not connect to my WiFi but would  connect at my friend's house to his Sky WiFi. Did all the usual checks and spoke to numerous virgin customer service people nothing made any difference, one got me to upgrade to a faster speed saying that was the problem, it wasn't, after the upgrade it still wouldn't  connect so i cancelled it. Next the technical staff tried to get me to sign up to some monthly subscription service saying they would be able to get me connected. I wasn't happy about that as i had connected numerous devices in the past without any problems and felt this was just some sales pitch. I ended up taking the laptop back and getting a refund. To replace it i have now purchased a HP Envy 360 and tried this evening to connect to my WiFi. Experiencing the same problem ' can't connect to this network ' after further investigation i realised both laptops require 6E connection. Does Virgin have 6E WiFi. Not a single member of staff including the tech people have mentioned 6E. So what's going on with virgin? I really want to keep my new replacement laptop. Will i have to find a new provider? Can anyone recommend BT Open Reach? Been with Virgin around 25 years.
