For the past few weeks / months I have been experiencing speed stability issues which are getting progressively worse. To start with, speed would drop occasionally to around 50 mbs (should be 150), but the speed drops are now happening with increasing frequency and it has got to the stage where the slower speeds are now the norm, with high speeds maintained only on odd occasions every 3 or 4 days.
I have tried rebooting the router (SH2) and a factory re-set with no success. All connections are good and tight. One thing I have noticed is that the "2 headed arrow" icon (above the power indicator) is constantly flashing. I understood (perhaps wrongly?) that this should only occur when data is being transmitted, however, I disabled all wireless functionality, and disconnected all ethernet connections to the Superhub and the light continued to flash. Does this indicate a router fault?
I called support on 150 and was told that he flashing light indicated stability issues on Virgins network which he assured me would be fixed in 24 hours, however I am unconvinced. The operator seemed reluctant to listen to me and seemed most keen to just end the call and move on. I have the feeling I have been fobbed off (but could be wrong). Service status on the web site is showing no issues.
Consistently slow / erratic broad band speed (measured via ethernet); Rebooting & re-setting has failed to resolve issue; all wires good and tight. Stats as follows:
Many thanks for the stats, I can see there is some problems with your downstream you have a large amount of Post RS Error, and also you logs show a few T3 error, you are going to need a VM staff member to check the backend.
Also to note 2 of the channels are very close to the RxMER (dB) lower limit of the specs.

From memory I believe the 2 arrows indicate synchronising / ready on the Hub 2. If you have internet then it's nothing to worry about however those T3 timeouts are concerning, I'd wait for someone from the forum team to double check. Most likely they'll send out a new Hub & if that doesn't work they'll do further diagnostics.
