I have a SB6141 and my internet service is supposed to be 250 down & 10 up. I've had this modem for almost a year. Everything was fine before there was an outage last night due to scheduled maintenance (according to the Xfinity app). I was getting 235down/12up with 8 bonded channels downstream and 4 bonded channels upstream. Now I only have 1 channel each way and my speeds are garbage. I spoke with a Comcast support rep and he wasn't able to fix it after walking through his scripted troubleshooting.

Any ideas/solutions?

tl;dr
Comcast did maintenance
Modem config is now borked. Speeds are slow.
Help

A factory reset of your modem will force configuration download, try that first.

Silly new Comcast customer question: How do you get to that page?
If it's an Arris modem, it's at 192.168.100.1

I'm not familiar with other modem brands so it may be another address if you don't have an Arris/Motorola.


There's a Comcast tech coming tomorrow morning. Hopefully he can fix it.

You know they're going to tell you it's your modem that's the problem and they can't do anything to fix it right? Their 'solution' will be to pay them monthly to rent their piece of shit......

God I fucking hate comcast.

I have a Linksys DOCSIS 3 modem which does not let me get to the internal page if you have it connected to the WAN. I have to unplug it first, so there's no real way to see how many downstream channels are connected that I am aware of.

My older Motorola DOCSIS 2 modem let me see the internal page though.

The "techs" that come to your home are just low voltage installer goons that have memorized where to click on a computer. His type of problem is going to require an engineer.

Sorry for the late update. Wednesday at around 4 am the modem magically fixed itself. I cancelled the appointment for the tech. All is well again, for now.
