SB6183 and just 1 channel up
Today my modem rebooted and afterwards I had all 16 channels bonded for download but just 1 channel for upload. New reboots didn't resolve the issue.
I contacted support (got dropped when they asked me to run a speedtest) and they said that everything is okay after changing the profile (?) without rebooting the modem afterwards. I get 450 Mbps on download and 12 Mbps upload with this 16x1 setup which is basically what I pay for.
I have seen quite a few uncorectable errors lately but I don't know if that is connected to this upload channel problem.
My fear is that
a) Comcast is no longer supporting DOCSIS 3.0 modems
b) during busy times I will not get my upload speed anymore as there is just one channel available.
How do I get my modem back to 16x4?
