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.

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:

None of the so call 'fixes' work as far as curing the DHCP problem that blights y the home network when you install one of these TP link devices.
Years of promises and more promises and delays and then so called firmware updates ... nothing stops them causing your home network to keep dropping out.
the BS about fixing the IP address in the powerline device is A Grade BS too....
Just advise people never to buy TP link kit. I have £200 worth of their garbage here that is useless so avoid it at all costs.

@PC_60 not sure why you reply to me but the latest firmware resolved all of the issues with my device. Works perfectly now. Just needed the 'disable DHCP' option.

@Solla-topee I got a TL-WPA7510 v1. I don´t have the option to disable it´s dhcp server and the thing is killing my whole homenet.
Please release a firmwarefix for that model too.
Just a button to disable it´s dhcp is fine.
It even shows in the log that it starts the thing at every boot.

Hi, do you mean your TL-WPA7510 v1 doesn't work at all at this moment, or it works but stops working after your router reboots?
And did you check the IP address on the client devices to confirm if the IP address is assigned by the TL-WPA7510 v1?
Please also provide us your network topology and LED status on your powerline devices.

In the log you can see it is starting the DHCP but it won´t shut down.
If I set static IP i can use the Network of the Powerline device just fine but that rouge DHCP of the Powerline just nukes connection for every autoassigned device.
Fix is simple, add a toggle to the control of that device so i can shut that thing down. But yeha i can´t and it´s not turning off automagically...
No restarting obv. doesn´t help. My Router is already up, after power outage I manually disconnect the repeater ´cause of that rouge dhcp. That used to work fine but now powerline device is just not turning off the DHCP at all...
Topology for that Powerline:
Injector plugged into the Router and the wall. Wifi part of Powerline set plugged into other outlet.
Yeha the TL set´s itself as default Gateway so i am pretty damn sure it´s the TL fcking up my network. Other confirmation?: None of these errors happens if I just do not connect the TL-WPA to the power... but sadly i ain´t got wifi then.
I got some devices which i can´t assign a static adress.
Only option is to add a damn user control to that device and just let me turn of the useless dhcp in the powerline thing.
