I have just had Virgin installed – Vivid 200 and SH3. Speedtests from Windows 10 machine give good results (200 up and 12 down). Linux box has 2 HDD, one with Ubuntu 15.10 and the other with Ubuntu 16.04LTS. Booting to Ubuntu 15.10 allows me to access the SH3 but not the outside world, this being on either WiFi or cabled. Booting to Ubuntu 16.04LTS allows me to access the SH3 and internet. However the Speedtest results are abysmally slow. As with Ubuntu 15.10 this is on both WiFi and cabled. Both boxes and OSes are completely up to date. No problems experienced with my previous ISP.
Yes just spotted that. I did originally post my initial query in both Tech Chatter and Networking. Looks as if they have moved the message from Tech Chatter to this forum. Nice if they could have let me know. I will remove this duplicate. if I can that is.
