Thanks for the info.
I've based it on speedtests and a number of downloads. Wired or wireless, it makes no real difference. A few minutes ago I saw speeds back up in the high 90s, but now they are back to 6Mb.
I take your point about having the same channels, as my broadband monitor showed a reduction in quality when I switched from 50Mb to 100Mb, but if I revert to 50 (or lower) I won't be paying for so much of what I can't get
