I've been with Virgin Media for years. Usually have pretty good broadband service. I hope I have added this topic to the right Select Board?!
I've recently signed up to CyberGhost VPN to add some cyber protection. My issue is that it appears to be difficult to maintain a connection when connected to the home wi-fi. I don't appear to have issues when using 4G or using other wi-fi. The issues re similar on iPhone XS Max and iPad Air 2.
I have tried to swap CG servers but the problem persists, with slow connection (in comparison to 4G and other wi-fi networks.
If anyone has any similar experience or knowledge to help, it would be gratefully received.
