I've upgraded to 500Mbps package and the speed tests don't appear to be reaching anywhere near.
Going through the help steps, it advises to post here.
My hub 3 is in modem mode and I'm using an Asus RT-AC68U router.
Downstream bonded channels
Channel Frequency (Hz) Power (dBmV) SNR (dB) Modulation Channel ID
As you are running your SH3 in modem mode this could well be why you're not getting the speeds on your package.
Have you tried returning the SH3 back from Modem Mode into Router mode and running a speedtest from the SH3 instead?

I haven't tried that yet. I've power cycled both and hard reset them. I'll give that a try. Do the stats look ok for this package?
Yes the power levels look good and are where they should be.
Nothing to worry about with both Upstream or Downstream levels.
