Intermittent loss of connection

[stu55y]

I'm experiencing an unreliable connection (Hub 4 in Router Mode) with regular disconnects (at least one per day, and where rebooting doesn't seem to get me back online).  I have been monitoring the connection using ThinkBroadband and also have noticed an unexplained constant spikes in latency since the last reconnect last night.

Here's a link to my live graph.

Would really appreciate it if someone has any thoughts on obvious issues.

Thanks
