Ok everyone! It worked great on my Technicolor TC8717T! Im running a Nighthawk R7000 and my speeds are finally hitting almost 300 Mbps on the 2.4 Ghz band! I had no problems with the 5 Ghz. Thank you for the FIX!
I attempted this configuration last night and had no luck. The problem with this modem is it has no "WAN" port. So do I just use one of the 4 ethernet ports, and plug the cable into the "WAN"/"Internet" port on my router? When I did that my router never got an IP from the ISP, thus no internet.
