Thanks for posting back here and my apologies for the late reply. I hope you don't mind me picking this up for Adam.
I've taken a look at your connection, the upstream power levels are now locked onto 2 channels and are within the correct range, which is good. There has also been no reported time-outs within 5 days of the router being online.
If you are still having the same issue, can you re-post the network log for us to check over please?
Are you able to create a Broadband Quality Monitor as this will check the performance of the connection? If you do set up the BQM make sure that you go into your router settings > Advanced Settings > Ping > and tick Respond to ICMP echo requests sent to WAN IP.
