• Problem #199 with my wifi

    I have a unifi controller (running on a pi) that had been working fine until mid-morning, when I had to shut down all of the power sockets downstairs.

    When I brought the power backup, the controller is running on a totally random IP, on a completely different address block 169.244.0.0/16

    My router is set up with:
    eth0 - WAN - cable modem
    eth1 - LAN1 - 192.168.1.1/24

    • Switches & APs are connected here
      eth2 - LAN2 - 192.168.2.1/24
    • Unifi controller is connected here

    I did have to have the controller on LAN1 to adopt the APs, and change the inform address manually, but the worked fine when I moved it back onto LAN2

    Even if I switch the pi back onto LAN1, it is taking an IP on 169.244.0.0/16

    I have the Pi's MAC set up in the router to have a static IP on LAN1 / 2

    Any ideas about what I'm doing wrong?

  • the controller is running on a totally random IP

    The Pi is running on a random IP, meaning that it receives it's IP via DHCP.

    You should login to the Pi and configure a static IP for it. Then once it's stable, login to whatever your Ubiquiti DHCP server is and configure a static IP map for the Pi that matches what you've just done.

    After that... you're good to go.
