Are both the two range extenders the same model RE450? 

We can use multiple extenders together to extend the wifi range, while to ensure the performance, it is not suggested to use them in a daisy chain, in this way, the last extenders will have the lower signal strength and speed. Instead, it is suggested to connect the extenders to the main router directly to extend the wifi range.

i have one extender as RE650 (first extender) which is directly connected to the router through WPS and the other one RE450 (second extender) is also connected to the router through WPS mode with DHCP off. The network works for a bit and then the second extender (RE450) gets a self assigned ip address while the first extender (RE650) is still connected to the network. 

i have tried restoring the device to factory defaults and configured it again but unfortunately same problem persists. Even tried with a different range extender, the issue is still the same.

Have restored my router also to factory defaults and configured it again but again no luck.

Hello, thanks for the detailed info.

Is the firmware of the RE650 already the latest? If not, update it and try to reconfigure it via the web UI: https://www.tp-link.com/support/faq/1411/

BTW, confirm the wireless password of your router is correct.

Meanwhile, try to disable the DHCP server (Settings-Network-DHCP Server Settings) on the RE650 when you set it up via the web UI.

On both the extenders DHCP IS OFF and both the devices have latest firmware. 
 

I have tried to configure the devices numerous times through web, then also the same issue. 
 

I am not able to understand which device has the issue. One extender is still connected on the network while the other device with the same settings as the former one gets a self assigned ip. 
 

it's not a router issue as one of the extender is still connected to the network and neither the extender issue as I have tried it with the different range extender as well.

i think I will have to assign a static ip on the device which is loosing connection while keeping the dhcp on the first one.

I've been getting the runaround by tp-link they're not going to help you one bit. I was told on the phone and confidentiality that they know there's an ongoing issue and it was going to be replaced since then I've been told that this phone conversation never happened and the email that I got that says please take a picture and if possible the proof of purchase which they wouldn't have been worded that way if they knew I didn't have it which I've been saying from the beginning.

Funny how this is still continuing on. And I told there is no issue with the Wi-Fi extender but yet there's another forum post with dozens upon dozens of people saying the same thing
