They have started rolling out a firmware update to the Hub 3 which seems to perform very well on that DSLReports Puma 6 test, based on the examples posted in the gaming forum. Hopefully it won't be long until everyone has it. It doesn't completely resolve the problem but seems to do more than the Beta firmware that some users have been trialling since October.
Hi Emma, I've been following the now 300+ page thread since it was posted in this thread on the 28/12/17. I thought it was already established that we were suffering with this issue but it would seem Virgin required the last 7 weeks to confirm.
I have not yet been pushed the firmware update and from what I've read, there are mixed reviews of it's effectiveness.
Post #3098 of the Hub 3 thread has now stated that the firmware that was thought to be a new update is just a trial with no expected rollout dates.
So we're no closer to a solution to the problem here.
In addition, I have now set up a BQM on my parents' VM connection (with the same firmware version as mine) and their connection is significantly better. Presumably there is something else happening here in addition to the puma 6 issue.
My connection with 9.1.116V firmware:
My parents' connection with the same firnware:
And yes, they are on the same 24/3 channels with the only difference being the packages. (ours being the more expensive "Gamer" package with a WORSE connection for gaming!)
Your parents graph looks very good indeed for 24 channels, probably one of the best I've seen for the SH3 with 24 downstreams. The package shouldn't make a difference as it's still connecting to the same number of channels.
