XB6 Gateway modem - How to test upstream, downstream signal and SNR?

Hello,

I have the new XB6 Bateway from Xfinity, and I'm trying to gather the info to address my signal continually dropping, but am unable to find the upstream, downstream signal level (dBMv) and Signal-to-Noise ratio (SNR) on http://10.0.0.1  (http://192.168.100.1 does not function at all).  Attached are screen shot of the available menus. 

 

Also there is no "Error Log" option to post. There is an "Events Log" but it does not return any responses, even waiting 10 minutes. Attached screen shot of Event Log menu.

 

Is there a user guide on how to test the Xfinity XB6 Advanced Gateway Modem model #: CGM4140COM ?   (I cannot find this by Googling, and I don't want to call XFinity tech support a 4th time before i have this info).

The gateway stats you're looking for are under Xfinity Network. What exactly are you looking to test?

Thank you! I found the Downstream (around -1 to -4 dBmv) and Upstream (42.8 dBmv) signal strengths, and SNR (38 to 41 dB ).  But I am unable to find or generate an 
"Error Log". There are 3 logs under Troubleshooting tab (System, Event and Firewall), but the Event log will not open.

 

My issue is that my internet connection is very frequently dropping for about 3 minutes at a time, while the Gateway cycles through the various lights and reconnects. I suspect it might be an upstream cabling issue, but I wanted to do my own due diligence before calling XFinity tech support for a 4th time, to avoid any unecessary in-person service visits.  I was following the top pinned forum guide to find the info; http://forums.xfinity.com/t5/Your-Home-Network/Information-Requested-for-Connection-Related-Posts/td...
