Help - Your ISP's DHCP is not functioning properly

Here's my setup:

  • SB6183 modem
  • Asus TM-AC1900 router

 

My internet was working until an hour ago when I had to momentarily turn off/on the power to the power strip those two devices were connected to.  Since then, the modem has had issue connecting to the internet.  Specifically:

  • Asus router log shows: "Your ISP's DHCP is not functioning properly"
  • On the modem, 3 solid ON lights (Power, Incoming, Outgoing), and flashing WAN light
  • Tried connecting directly to modem via ethernet cable, doesn't work
  • I noticed that in my Xfinity app, the SB6183 shows up as offline, even though it's powered on

 

I've been on the chat assistant with 2 different agents for over an hour now and still not fixed.  I even sent one of the agents the link to https://forums.xfinity.com/t5/Your-Home-Network/Your-ISP-s-DHCP-is-not-functioning-properly-ASUS-router/m-p/3331178 and they disregarded it without any reason.  Help?

Unplug the modem and the router and shut off the computer. Wait a minute. Plug in the modem and let it fully sync up (Online light lit steadily). Now plug in the router and let it fully come up. Lastly, turn on the computer. Any joy ?

The reason that I stated to power things up in that order is because you stated this;

You can't power them all on at once with a power strip. It needs to be done in the proper order.

 

You also stated this;

 

Tried connecting directly to modem via ethernet cable, doesn't work

 

You need to powercycle / re-boot the modem each and every time that you change the device that is being directly conneted to it in order for that device to be able to obtain an internet connection.
