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.

If your model is not listed or the issue persists, please report back with the information below to help locate the issue.
Or send a support email to TP-Link technical support with title ‘[Forum ID 265692] Powerline Extender Acting as the DHCP server’ to get further assistance:
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:

@Pmalinko Because its a quicker and better solution than whatever TP-Link has.
I think the beta software actually made it worse and I tried flashing the release firmware they have on their site and it wont go back

@riahc4 I note that there are a lot of warnings about the support for the WPA8630 models in OpenWRT and risks of bricking the device. They advise waiting for a stable release.
https://openwrt.org/toh/tp-link/tl-wpa8630p_v2
I also note that most of the OpenWRT forum posts mentioning the WPA8630 devices are referring to devices that have been bricked.

It feels like life may be more disrupted by going this route than the current mess.

Hello @riahc4 , may I know which beta firmware is on your device now and which official software you tried to flash back to?
If the device has upgraded to (EU) version beta, also try (EU) version official firmware, country version should be the same noted on the device label most of the time.

@dunxd Right, I installed it and it is not a stable and limited release. Above all of having to install an additional web interface to manage it by user interface. Reverting it to the original is very complicated. I do not recommend it if you do not have a high level from the command line.

@Solla-topee For when a firmware that disables the DHCP?
3 months have passed since the beta firmware publication, to add to the 4 years since the launch of the last official firmware.
There would be another one to throw 100 euros in the trash as a user said in another post.
Great job guys!!!

@Zoltar74 I did not get the estimated date either, but I know the project for the beta has been established, it probably takes longer time.

@Solla-topee "established"??? EOL (End of Life) in the website, only last firmware for download. New products with same problem.
Ummmm I'm going to buy another new TP-LINK product immediately. Thank you very much.

I have been suffering with the WPA8630p for about a year now, basically I couldn't figure out what the heck was going on when whenever this device is plugged in it killed my powerline network. the router would have stayed up and running and direct wifi to teh router would continue to work by anything that was on the powerline circuits just went down randomly. No power cuts and ONLY when the TL-WPA8630p was used.
I have struggled with TP-Link support, indeed one of your 'Chat support people' simply said the device was incompatible with BT hardware ... I may still have the chat transcript to prove it.... then months later and hacked off at having spent such a large sum on these devices I find that there is a DHCP issue being discussed that was never mentioned by support....
Still trying to get some value out of the device I looked again and found this thread in which it appears TP-LINK know about the problems but aren't doing much to fix it, ahe but they did issue a TL-WPA8631pV3 device.... heaven knows if that works I haven't dared to spend any more on TP-Link kit, and in anycase it appears having read this there still isn't a fix and that I wasted my cash.

@Solla-topee It's unbelievable to sell a product with such an option and to not add the setting to disable it. I hope the final firmware will be released soon. This DHCP server screwed a part of my network for days and it took me a f**** while to figure out what was the problem.

@PC_60 While tracing your case, it seems that instability occurs when you try to use TL-WPA8630 a different brand of powerline KIT. ' TL-WPA8630P become unreliable when used with BT Mini Connector powerline kit. ' If that the case, we recommend to use powerline units from the same manufacture or compability or performance can not be promised.
Theoretically you can have more than powerline network under the same powerline, you could use this powerline KIT solely to extend network ( main unit to router, extender in another room), not pair with the BT one and see if there is DHCP issue phenomenon described on the page 1 of this thread.
