I'm new here too, but have been on BT Broadband for two years now.
Recently, the hub has been dropping out intermittently. The 'power' and 'wireless' lights stay on, but the 'broadband' light goes off fully. After about five minutes or so, the broadband light will start flashing orange, then come on fully in blue again.
I am wired to the computer and never use wireless.
This is becoming a pain now as I trade financials online.
The hub is never switched off, althiough is in a cool area and doesn't appear to be overheating, could leaving it on all the time be detrimental? I was advised by a techy to just leave it on, as continual heating /cooling may be worse for it longterm.
