I am sorry to hear you are having problems with lag and speed since the upgrade we will take a look.
The area is looking quite good, low traffic levels and error free. The connection is looking good also, all levels nicely in specification. Are you still having problems, please would you try speedtest.net leaving the default server as this will hopefully remain on our network.
Where are the host servers based. UK / US or Europe
Superhub / SH2 / SH2AC / SH3
Modem mode or Router Mode.
Have you done a speed test on a different device
-- Red (VM SH2 AC Beta tester) Running on 200Mb VM service with SH2 AC in Modem Mode, with a ASUS RT-N66U router. With this setup I get Fantastic WIRED and WIRELESS Signals in my home. I dont work for VM. But I work in IT, and I know my tech. My advice is at your own risk.
