AFAIK, the Samknows Realspeed client was put into the Hub's firmware some time ago, hence it "should" work.
However VM are, at the moment still working on the Hub 5 firmware, so could have upset something?
A 60 second pinhole reset may help, but who knows.
Post the power levels, Pre and PostRS errors and network log from the Hub. Also setup a BQM to monitor your circuit www.thinkbroadband.com/ping
Once done we can comment.
