Re: New Asus RT-AX56U router - 'Your ISP's DHCP is not functioning properly' message

I'm having the same issue here, after a brief power ouatge this morning. I have an RT-AC66U ASUS router and a Motorola cable modem. I can connect directly throigh the modem but get the above DHCP message in the router for the WAN connection. I also noticed that the modem does return a different public IP address than it has for the past few years.

 

@ComcastChe , any help would be appreciated! Thanks!

I'm having the same problem. I'm unable to get a DHCP address on my Asus router that is connected to my Motorola cable modem.

Oddly enough when I switch out the router for an older one, it works fine. Also if I connect my laptop directly to the modem it works fine. I tried cloning a 'good' MAC address on to the ASUS router but for some reason that doesn't work either.

I'm a bit mystified at this and suspect it's some configuration problem on Comcast's side. Please advise.

I am getting the same Your ISP's DHCP is not functioning properly error, except with an Asus GT-AX11000 router.  In addition, it seems like if i plug a computer directly into my modem I am not able to get an internet connection now, however if I connect to my current Netgear Nighthawk AX120 I am able to access the internet.  Any help would be appreciated @ComcastChe

You seem to be the go to guy for this issue.  Worked with your colleagues via chat today for hours and we have managed to get it to where it happens intermittently, but it is still happening.  Any help would be appreciated!

Hi @theronmoore

 

Thanks for creating a public post, and sending me a private message with details of your experience thus far. I can understand how much of an inconvenience this can be and want to help get this resolved for you as well. I've replied to your private message. Please reach out when you have a moment to do some troubleshooting with me, and we can go from there! 

 

@nnul@kangarooster, and @dzampani58, I am more than happy to assist you too! Now that you have made a public post feel free to send me a private message with your: 

 

* First and last names and the numbers associated with your street address. 

 

To save extra time, please also include the MAC Address of the modem you're using. If you have any external devices connected to your modems like routers or external hard drives, for example, please prepare to unplug those during the troubleshooting process. I look forward to chatting with you all soon. If you happen to reach out while I'm off the clock, I'll reply in the order your message was received when I clock back in.  🙂

I’m having a similar issue with the same message, and I’ve read getting a provisional signal to the modem can be a fix. @ComcastChe Please help if possible!
