My router is a Luma and I installed Openwrt 23.05.
Post sysupgrade and installing Luci, I was able to access it and wanted to change the settings to a dumb AP.
I put in a static IP (192.168.55.4), the dns and gateway as my router (another luma is 192.168.55.1).
Post this, after reboot I am unable to access the AP via Luci. I have connected the AP to my main router via LAN port.
I have rebooted the main router and the openwrt router multiple times.
Using Fing I see the router as 192.168.55.4 but ping or browsing or ssh doesnt work. The ip address seems to change to a random ip when i dont connect to the main router at that time I am able to ping but still no Luci.ssh.
One of the possible issues seems to be that Luma seems to reserve the first 20 ips for its mesh network.
I am sure I didnt do the settings correctly but anyway to get access now other than using serial connections as its a pain to remove the backpanel (again).
Are you certain you entered the address properly when you changed the config? What does fing say about the device at 192.168.55.4? And does it fail to see it if you unplug the AP?
We can try to troubleshoot the situation itself, or you can jump to recovery methods.
The fastest way to recover is likely just to use failsafe mode and reset to defaults. Or, you could view the config and try to fix whatever is wrong.
