Would suggest you talk with Comcast support. They control the cable side which is what you are talking about.
No, there's no setting to change.
You can check to see if you have any amplifiers, attenuators, or splitters in line. Remove them if you do. Check the coax line for kinks, damage, extended runs, issues, etc.
If that doesn't help, you'd want to contact your isp to check your line.
yeah, checked all the normal stuff, splitters, cables, etc.. I'm in a rental home, moved in 1 month ago, Comcast came out did their thing then left. first check after they left I was getting all 8 upstreams locked. couple / few days later I was running on only 1 channel. researched issues common to " upstream / bonding ", found that Ideally signal strength was 38-48 Dbmv... if signal went too high ( mine showing 57 ) then bond locking can have problems. my old netgear 300 had a option in advance setting to toggle power request to comcast. do not see that option on my nighthawk, do not think a Attenuation problem exist cause I am getting too high of signal / decibals. as far as Comcast, please, I don't need someone to come out, tell me the line is fine and it's your equiptment, and by the way sense it's you equiptment here is a bill for 75.00 hahaha. not funny. HOPEFULLY, big hope, I can get a tier II tech that has admin rights and can do more than read from a manual
all points to Comcast, I have obtained tier II phone number. once they lower the signal strength I'm sure all will work.. Call it resolved..
