Is it an Asus router? It's a bit of a known issue and there are several threads about it. Just search for "Your ISP's DHCP does not function properly".

ASUS explains the "Your ISP’s DHCP does not function properly" message this way:

The router has detected that the WAN port has a connecting network cable (RJ45) but does not have the ability to access the Internet

So you may want to check the suggestions in https://forums.xfinity.com/conversations/your-home-network/connection-troubleshooting-tips/602da777c5375f08cdea3db9 . Especially check downstream power levels and SNR, upstream power levels, and the event log.

What is the explanation, and what is the fix?

My ASUS router says "ISP's DHCP does not function properly" every time I lose power or turn off the router. If I connect my cable modem to my PC the internet is working fine, so it has to be a router issue. Or maybe the way Xfinity's DHCP works with the Asus router is the problem.

My solution was (my router had the latest firmware available from Asus):

1. Turn off the modem

2. Factory reset my router.

3. Turn on modem

4. Setup the router's WIFI etc.

Hope this works for others, because I spent many hours laboring on how to fix this issue.

I have an Asus AC1750 paired up with the Arris SB8200 modem. After spending several frustrating hours I stumbled on the Asus Router app. After downloading to phone, I got into the router it queried about DHCP, I answered yes, problem solved!
