Solution Powerline Extender Acting as the DHCP server
This Article Applies to:
TL-WPA7510, TL-WPA9610, TL-WPA8730/8630(P) V2, WPA4220 V3, etc.
Problem Description/ Phenomenon:
What is Smart DHCP, and How does Smart DHCP work? Visit TP-Link Smart DHCP Makes Network Configuration Simple.
Some users may find that after the power outage or router’s rebooting, even after router’s internet is back and up running, client devices still get IP address from powerline extender, and cannot connect to the internet.
Note: if router loses internet and then goes back afterwards, powerline extender will do a scan automatically, if it detects another DHCP Server is running, it will disable its own automatically (when powerline units remain paired), and the devices will get IP address from main router then access the internet through that.
Troubleshooting Suggestions:
1. Double check if the main router’s internet is actually back ON and working fine.
To confirm this, wire a computer or laptop to another LAN port of the router using an Ethernet cable, leave the main powerline adapter connected to the LAN port of the router as well, check if you can access the internet successfully on the computer or laptop. If yes, that means the router's DHCP server is up and running; If not, you will need to check what's wrong with the router after the reboot or power outage.
2. Make sure the powerline adapter and extender are still paired (house LEDs are ON), show us the IP address on the clients devices. Compare that when the internet is good and when it is not.

1. How did you find out powerline device's DHCP server does not work properly? Did you often reboot main router or is there often power outage in your house?
2. Does router’s internet work fine at that moment?
3. LED status on both powerline units.
4. Brand and Model of router, the network topology, for example:
ISP modem --- Router Archer C7 --- PA8010 .... <powerline> ...WPA8630P --- Asus laptop model X.
5. Model & OS of devices that connected to wireless powerline unit.
6. Model number & firmware and hardware version of your powerline KIT, update the firmware if it is not the latest version:

The issue of dhcp perhaps did not prove it, nor has so many manufacturers been able to correct it in 5 years. maybe it's a problem of design, or desire... I do not know. What is clear is that TP-Link has not wanted to continue developing the product for a long time, preferring to take a v2 a v3, but with the same problems from what I see. A way to leave out part of your customers.

@Zoltar74 I saw that video last year. The description of the video specifically says:
The firmware can be found online and/or on the tp-link community forums. The firmware is not provided here.
They suggest looking back here for the firmware - a bit circular.
The video shows how to update the PowerLine aspect of the WPAs which does not have anything to do with the DHCP server. The link to github in the video description is for an open source version of the Qualcom Atheros Powerline Toolkit.
I'm still not sure how this is helpful in relation to this thread.

I have found out that WPA4220 v5 (EU) version had a beta 1 year ago and no updates since then, moreover knowingly that is failing that firmware.
TL-WPA4220_V5: https://static.tp-link.com/beta/2021/202102/20210220/TL-WPA4220(EU)_V5_210209.zip
I was asking because I have seen that WPA4220 V5 US version had a very recent update:
TL-WPA4220(US)_V5_20211105_Beta https://static.tp-link.com/upload/beta/2021/202111/20211111/wpa4220v5-us-up-ver1-0-0-P1%5B20211105-rel67545%5D.zip
So I don't understand why EU, which is almost the same, has not received the same update yet...

When I look into the wpa8630pv2_eu-up-ver2-0-3-P1-20171018-rel36564.bin file (it's just a ZIP), I see that in the \web\data\ folder, there are settings files related to the DHCP server, one of which is dhcpServer.settings.json, which contains interesting text. It seems that for you guys, it should be extremely easy to disable the DHCP server altogether.
Why don't you just release firmware for all models, in which the DHCP server is disabled or at least can be disabled?

@Jvmd
The wpa8630pv2_uk-up-ver2-1-1-P1-20210716-rel63086tp-debug.bin file within the zip is different and a mix of binary and text/labels for a loader app. So no sign of any such json scripts.
The fact is this has taken way too long to address for these devices when set against the release of later version hardware. My guess is this is a fob off forum and no firmware update will be issued. What we get are sidelining tactics.
Note there is no warning notes or updates to the actual device support download pages and hasn't been in how long?
