The BQM posted is a live link, and shows horrendous spiking of latency that certainly would be a contributor to poor streaming and other latency sensitive uses of the connection.
I must say it magically has gone very clean at 5 am this morning, fingers crossed it was a network or area fault that's now been resolved. If the BQM remains as nice as it has been since then, we can probably rule out a continuing connection fault, and should the problems persist then they are likely down to wifi.
