Sorry for the connection problems. I've taken a good look at your network and the local area and everything is performing well at the moment. It might be worth setting up a BQM so we can take a closer look.

The BQM latency may be due to this reason however I think it may be a bit of a red herring as you are reporting slow speed problems.
Your line and hub are looking good, area traffic is low, you are not being throttled, nothing jumps off the page that may cause you lower speeds. If not so already it is best to use www.speedtest.net leaving the default server as this will normally remain on our network so tends to me more accurate that some other speed test sites. It looks like you may be using your own router, it is important to make sure you are measuring speed over a 1Gbps Ethernet connection. If it persists it may be worth trying devices direct into the hub Ethernet (sans router) (hub may need a reboot after connecting by the way to allow an IP address) to see how that goes.
