CM1200 Internet Speed Problem
Hello fourm, I recently purchased a Nighthawk CM1200 Modem and a Nighthawk R6700 Router. The router was the first to arrive in the mail and I decided to set it up with my previous router. All was goo...
As mentioned before, the CM1200 has multiple ports for Link Aggregation and ISP specific IP address asignments. The only couple of routers that support LAG is the NG R7960P and R8000P. All other routers only support 1 port connection with the CM1200 with Port #1.
Be sure the LAG is disabled on the CM1200 modem.

The router was the first to arrive in the mail and I decided to set it up with my previous router. All was good with the router and my previous modem. Upon installing the new modem, the CM1200, I had to reset the router and attempted to power flush for it to retrieve the IPV4, Physical, & Mac address. Upon a rest and flush, the router wasn't retreiving the information from the modem. I called tech support and they kindly guided me through the process and got everything squared away.
The issue I'm having now is that with the router connected to the new CM1200 modem. When ever I have more than one port occupied on the CM1200 my internet speed flucuates eventually killing itself having the internet not work. Whenever the router is solo connected to the modem, everything works fine.
Overall, when I have my PC and router connected to the modem, it lags out killing itself in speed. When the router is solo connected, all is fine. Any suggestions on what can be done or should I return the modem for a new one?
