its a flashed bt homehub 5a and been quite stable until today, i tried my non openwrt homehub too and my fritzbox 7530 and same connectivity issues, so its line issues as usual.
seems someone at openreach tried changing our speed profile possibly, but the line cant handle it (the whole issue im trying to get resolved)
Seems to be stable at 5mbit down now for a while...

nice speeds huh, not quite the 39mbit ........
The annoying thing is wiltshire online think i dont know anything, im a ex network engineer and i know about routing etc, and my router etc is plugged into master socket, no extensions, connected to router via 1000mbit ethernet, they still say its internal wiring probably wifi etc. OPENREACH.. its a line issue, your infrastructure in my village sucks, 1mile long + pre copper aluminium lines ....... underground pits that flood when it rains. Just connect the last properties to the cabinet not even 70m away....
