I am half wired and half wireless ........ Xbox , Big Telly and 2 Home Clouds are wired everything else is wireless.
Slow downs are predictably late afternoon through to early evening. The 30 second service "Shut Offs" are completely random but extremely frustrating as I listen to Internet Radio Steams and Podcasts most of the day and night.
I am tempted to have a go with the Hub 3.0 if I could be reassured that I could revert back to the SH2A if things do not work out.
Also I have recently started using a paid VPN service to avoid the tracking and polling which had reached such a ridiculous level and any sense of confidentiality or privacy had disappeared long ago.
Many thanks for your prompt replies and advice .... much appreciated
