HI, I've been using Deco M4 for around 2 years now without any major isues, however over last few days I'm not able to connect my PC to the network as I keep getting "duplicate IP" on both WiFi and ethernet. My netowrk consists of two M4's in router mode (one on first floor connected to ISP router sencond on bottom floor working as a repeater).

Now the funny thing is I also have a TP link extender TL-WA860RE that I sue to manage wifi for my CCTV cameras, and when I connect over WiFi to extender my PC gets IP allcated without any issues and I am able to connect to internet, but not through the main network.

It's worth mentioning I reserved IP adress for my PC through the Deco App and even then I get duplicate IP

Ethernet adapter Ethernet:

   Connection-specific DNS Suffix  . :

With DHCP enabled I get 169.254.... Ip address

Also, all mobile phones, TV's etc work absoultely fine connected to main WiFi

Any ideas on what is going on would be much appreciated
