Netgear C3700-100NAS losing connection

Netgear C3700-100NAS losing connection

A few months ago I switched from the old Comcast provided hardware to a new modem/router combo (Netgear C3700-100NAS). Now that I've started doing video classes again, I think I must have set something up wrong. I can't go for an hour without dropping the connection. There was a period playing a video game last night where I lost the connection every 10 minutes for a half an hour.

 

Happens to the computer that's hardwired to the ethernet, so it's not the wifi.

When this happens, it looks like my downstream light is blinking.

 

I think I've got all the details requested below, but let me know if I missed anything.

Re: Netgear C3700-100NAS losing connection

Can't see your first pic. Since you are a new poster, it likely needs to be approved by a Forum Admin.

You could try hosting it at one of those free third-party pic hosting sites and post the link to it here.

 

Those router portion logs are unhelpful in your second pic. The modem portion's RF error / event logs would be more helpful.

Re: Netgear C3700-100NAS losing connection

Hello regansbox. We appreciate you visiting and posting on the Xfinity Forums. I can assist with troubleshooting your intermittent connection issues. In order to have a better insight, I will have to poll the CMTS for real-time and historical RF signal reports from your modem, and check your local Node/Plant for signal degradation / errors. To get started, please send me a private message and include your full name so I can access your equipment. You can click my name (ComcastJoeTru) to view my profile and send me a private message. Click "Send a private message" and private message me.
