My home LAN has my desktop ethernet connected to VM Superhub2 ac. My laptop is connected to an Ethernet switch which then connexts to the Superhub2 ac.
On startup both computers can access web pages and the Superhub settings. Sometime later the desktop Chrome or Firefox browsers will not open any web pages or if they do they might take five minutes or so to open any pages.
Both computers use Windows 10 Home 64 bit. Using Speedtest I get 219.07Mbps/12.28Mbps.
I use AVG Internet Protection paid for version but even with this disabled web pages have the circling arrow and do not open.
