ISP's DHCP is not functioning properly (ASUS RT-AC68U router)

Hello, 

I'm experiencing an issue similar to the one reported here:

Xfinity came out to work in our area recently, and ever since then my router loses its connection every hour our so. This disconnection is always preceded by a DHCP error:

Dec 11 21:02:30 WAN Connection: ISP's DHCP did not function properly.
Dec 11 21:02:31 nat: apply redirect rules
Dec 11 21:02:35 WAN Connection: Ethernet link down.

It looks like @ComcastChe  was able to solve it by sending a provisioning signal to the modem. Wondering if that's the solution for me as well? Thanks
