Hub Power & Reboot

Hi all,

For the last month or so, my modem has been dropping power levels rapidly (from between 2.5 and 3.5 down to -1, then -7, rebooting the Superhub and reestablishing a connection. This seems to be getting worse - I experienced it 5 times last night. I'm also having hundreds of thousands of Pre/Post-RS errors as well. Some channels are worse than others but all channels have at least several thousand post-RS errors, some over a million as of my last reset.

Is this expected behaviour of the modem? Does it normally reboot when power levels all drop?

I've logged this behaviour during a couple of disconnects and this is what the power levels look like (sorry for crap formatting - columns 2 to 7 are power levels, 8 to 13 are SnR levels I think?)

Below is an example of what the power/SnR levels look like when plotted over time (top: power, bottom: signal) - is this normal? (Please note the below image does not show any total disconnects, just huge sudden drops. I can find some graphs of total drops if that helps.

Would love some feedback as to whether or not typical Superhub behaviour is to reboot in these scenarios or whether I perhaps have a faulty Superhub or if I need an engineer booking?

Thanks!

Re: Hub Power & Reboot

Still can't upload the image... trying to resize it. 

EDIT: I don't seem to be able to post images for some reason. They upload, display correctly in the preview then show as yellow warning triangles once submitted. Maybe due to my low post count? Anyway, it just shows power levels taking very sudden drops (on all 8 channels), followed by slow rises, then sudden drops again (and repeat).

Re: Hub Power & Reboot

They stay as yellow triangles until the VM mods get to them and pass them as OK - can take an hour or two.
