Hi, I've been using a RapsberryPi 3 with LibreElec sucessfully for ages. My router started acting up, so I replaced it today. Both routers were Linksys WRT series models and both have exactly the same settings. All my devices work except for the LE one. On that, I get the wifi swapping between associating and idle. It just won't connect.
I made a brand new sd card and installed that. If I connect via an ethernet cable, then I can ssh in, use connmanctl, agent, scan wifi, services, connect {WIFI NAME}. That worked. Then I disabled the wired network, edited the Wifi connection and told it to connect automatically, then told it to reboot, and then I'm straight into the same associating - idle - associating - idle loop and it doesn't connect.
I've tried changing the Wifi channel to 10. I've tried explicitly setting my country to GB.
I'm at a loss. As far as I can see the router settings are the same on the new router as the old one (it is a newer model though). ALL my other devices work perfectly.
Any ideas? I can only connect to a cable while setting it up. Its usual location has no cables.
It's similar to this problem : RPI4 Network Error: Input/Output Error for wireless
I tried looking at the logs but couldn't find any errors. I not managed to copy one as frequently once it gets stuck in this loop, it sometimes reboots after I enable the wired network.
Where would I look in the logs for network errors.
Incidentally, my original SD card won't do the connmanctl sequence. It doesn't ask for a password at the connect stage, it just displays an error and won't continue.
Help please!
