Poor connections with our “superfast” broadbans for the last few months now.

[MaeLewis]

We've been having problems with our broadband connection for the last few months. Wifi connections just stops in most devices, we've been turning on-off the router to reset it up to 4x/day. Even bought new router just in case its the problem but still the same. It's frustrating, it's supposed to be superfast broadband, and every time i ring & checked, i get told there's nothing wrong with our connections. Help!!!
