Start at square 1. Its pointless to troubleshoot a router if the modem or line is the issue.

1. What speeds do you get directly connected to the modem? 

2. the R7960P has wan link aggregation. If you're using it, disable it. Link aggregation has had issues for netgear/arris/etc. its been problematic

3. Take a screen snip of the modem's cable connection page. Make sure you get all the info from that page and post it here. It shows your link back to the isp (a snap shot).

4. If you are speedtesting, don't trust the built in app's speedtest. i haven't found it even slightly reliable. Make sure what you're testing on is hardwired in and try dslreports.com or speedtest.xfinity.com   The others have had issues saturating gigabit. 

5. firmware on the router? 

 

Start at these and let me know results. Like I said, its best to ensure you have full speeds at the modem and then you move on to testing the router.

plemans thank you so much for reaching out. When unplugging the modem from the router and going directly to my laptop, it doesn’t connect at all. I get the message “Ethernet has a self assigned IP address and will not be able to connect to the internet.” I agree testing the modem first is best practice, what can I do to get a working connection from the modem to the laptop?

      That was the first move I made and it was successful. Now on chat with xfinity to verify my speeds. Will get back shortly with an update. To answer your question, I have 3 different MacBooks that I can try

        If you log into the modem (192.168.100.1) and click on cable connection, take a screen snip of that and the logs. Post that back here.

        And then speedtest it off the sites I recommended.
