Update : Issue confirmed by TP-Link support, fix will be pushed via new update.

Today I saw a update in my Archer C80, and I installed the update, now the firmware version is v1.12.0 Build 221010 Rel.35508n(5553), but after that my network went down.

Earlier I am using PiHole as my DHCP server, it was working perfectly fine, but after updating to latest firmware, my network went down, router suddenly change it's ip address to 192.168.0.61 from 192.168.0.1, and all the clients suddenly lost internet, I have restarted the router multiple times, but issue still there. Then Idisabled the DHCP from PiHole, and enabled the DHCP server on router, and changing it's ip address back to 192.168.0.1, it did fix the connectivity issue, but I don't want to user DHCP server from Router.

In brief.

• I am no longer able to use external DHCP server (I was using PiHole for this to manager my connected devices).
• If the external DHCP server enabled during update, somehow default router management IP (192.168.0.1) getting changed to 192.168.0.61, I have to disable the external DHCP completely and reboot router to getting back it's default management IP.
• I enabled the DHCP server in router and added PiHole IP as DNS IP for my network, but it is getting changed back to 192.168.0.1 automatically after reboot.

I guess this is probably a bug introduced in new firmware. can this be fixed?

Also, please let me know if I can downgrade the firmware to the previous version?
