Ok. Go to http://10.0.0.1
Log into the gateway with the following information:
password: password (if you havent chnaged it from the default)
When you log in, if for the first time, you will be prompted to change your password. After that, click connection and then click Xfinity Network. Scoll down to where it says Downstream and Upstream, make sure you get all the Downstream from the table, it is a scrollable table. Also, post the upstream signals as well.
Ironlung: How is it going now? Have you had any success with comcast or settings? We upgraded a week ago to the XB6 and are having pitiful results.
We directly connected a windows-based laptop and that is getting ok speed but our wifi connections are awful. Four long calls with comcast, two different modems, two tech visits and we are getting a *shrug* response from them.
