^ reboot your modem and lets see if you still have bonding alot of people report it goes away after a reboot

Re: Spokane, WA

Re: Spokane, WA

I'm kind suprised actually

Me Too!
I was told by a couple Comcast techs a month ago, there was no plans on upstream channel bonding in the Spokane area this year and maybe next.

Wayne....

You haven't learned not to ask the techs about things yet??

In all fairness and as a former outside tech, we are usually the last ones to hear about things like that.

And I don't recall when I first saw the 2 up channels..... its been a few weeks at least.

Schaumburg, IL - Lost the multi-channel upstream

Lost in State College, PA

Well, unfortunately mine has also reverted back to 1 Upstream Channel. I didn't reboot as you did.

Re: Schaumburg, IL - Lost the multi-channel upstream

I didn't manually reboot it. From the logs, there were 2 reboots. The first around 2:07am, and the other around 4:41. Probably due to Comcast shifting the downstream channels around.

Looking at my log today, it appears that my modem rebooted sometime after 3 am.

Just remember that the modem's log does NOT take daylight savings into effect, so you need to add one hour to the time.

It's hard to tell anyway, because the time didn't sync after the T4 and other entries till much later.

upstream bonding disappeared here too now

Lost in East Bay, SF Bay Area

Modem rebooted itself 30 minutes ago, and lost upstream bonding here in East Bay, SF Bay Area.

Back to single channel in Clovis, CA

My trusty 702G hasn't rebooted yet, so I still have 3 channels.

Edit - My hateful 702G just rebooted and now I'm down to 1 64 QAM channel.

Re: Evidence of Upstream Channel Bonding - Post Here

Still got 3 channels upstream here in Oakland, SF Bay Area

Still got 2 channels upstream here in Spokane, WA

I rebooted my modem yesterday and it still has 2 upstream channels. But from the above I don't have some fantastic upload speeds.

I'm on Extreme 105/10 BTW.
