Keep getting log below from the c7000 modem with t3 and t4 disconnects. Any thoughts on this? Dhcp on r7800 set to use computer mac address.

    Please take a screen snip of your cable connections page and your logs. 

    get all the info off the connections page as this shows the upstream/downstream connection to your isp.
