Started Unicast Maintenance Ranging - No Response received - T3 time-out

Been having pocket loss or disconnecting from the internet at random times and some being for 12 seconds or more at a time. It went away for a little bit after talking with customer support a couple months ago where I asked them to roll back an update for my modem that some online forums have said could lead to this issue but the issue is back again and been going on for a couple weeks.

My Modem:Nighthawk CM3000

Firmware Version V6.01.04  This and the preveious version of firmware has been linked to issues before according to some reports.

What do the modem's signal status values look like ? Try getting them here; http://192.168.100.1 


Please copy all of the text in its entirety of the *Downstream Power Levels*, the *SNR's* (Signal to Noise Ratios), and the *Upstream Power Level* numbers and paste them into your next post.
