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.

Thanks, I've picked up the TL-WPA8630 V2 again (it was gathering dust because of this issue) and installed the firmware update. I can confirm that the web interface now finally has the option to turn 'smart' DHCP off completely.
I'll monitor whether this solves the issues I had with the device.

I'm with 1.0.1 Build 220527 Rel.32074n (6985)
BETA for 4220 V5.0
But still don't see that
Looks they have revamped a lot the interface in the new versions removing DHCP

@Solla-topee Updated the TL-WPA8630p V2 with the firmware and yes when you browse to the device itself you can tell it to switch off the DHCP.....
Does it work and stop the home network losing connection - No, its a complete fail does not Work.

Hello @PC_60
Appreciated your further feedback. From the ticket note, the Windows PCs lose internet connection when wpa8630P is powered ON even though that PCs are NOT connected to wpa8630P, it could be something else relate to the network topology, I'd double-check your case with our seniors and follow up on TKID211213824& TKID220121771 .

I still can't see a fix here for the TL-WPA8631P v3.0
The latest firmware I can see is
3.0.0 Build 20210625 Rel.42417
Which has no option to disable DHCP, and so called "Smart" DHCP still kicks randomly.

Hello @Toopy
It seems your unit is not the latest firmware, can you check the country version of TL-WPA8631P V3, is it of (EU)/(UK)/(US) country version on the sticker?

Mine is an AU version, it is running the latest available shown in your link. Did you not make an AU version of the firmware?
