changing wifi setting in raspberry pi.
hi all, i posted this in the klipper discord, but haven't heard anything yet. hello all, i recently had to factory reset my router. i put in the same ssid and pw settings but i lost my pi. i checked the ratos-wpa-supplicant on the sd card, but it does have the right ssid and pw. ALTHOUGH pw is # in front of it and below it has another psk that is not #, and it has a very long alpha numeric string ( maybe 50 characters ). So question is, is there a solution in the wpa supplicant, or will i have to get a keyboard and monitor on the rasp pi and get into it. Which leads me to this. i did do that and the boot up sequence looks good, but it will auto load klipper. how do i stop that or get out of klipper, back into the command prompt screen? i can't control anything once in klipper. no keyboard commands help me navigate. i move a mouse and start clicking but what it selects is pretty random.

I fixed my issue. turns out for some reason my router was producing 2 ssid's that had the same name at 2.4 no other device could detect these 2 ssid's but somehow the raspberry pi could. i created a guest 2.4 ssid and connected it to that using the ratos.local/configure and it finally connected.

If the PI can't connect to the wifi it should start it's own hotspot. If that's the case, just use the configurator to set the wifi again.

thanks!! will try it out
Hey there! After connecting to the raspberry and connecting to the wifi, the raspberry hotspot disappeared (all normal I understand) Then I tried to Connect to http://RatOS.local/ the browser cant find that adress and I dont have access to much routers admin interface so I can check the IP for the Raspberry Pi. Maybe do you know how yo reset the Raspberry to the hotspot generating point to make it connect to a different wifi? Thanks for any help 🙂
HI, UPDATE, i connect to the configurator, select my ssid, and put in the password. rasp pi reboots, but still displays a ratos hotspot. its not taking to my ssid 😦 is there a manual way of connecting? i've used 2 different devices to connect to the configurator, and i've tried this multiple times already. any suggestions besides reimaging the rasp pi? that would be a HUGE pain.
So unless you somehow disabled wpa-supplicant or otherwise messed with the network configuration, that means you either mistyped the password or the access point denies the pi for some other reason. You can edit the ratos-wpa-supplicant.txt file on the /boot volume yourself, but it's the same thing.
I'm not sure if there could be issues with weird special characters in the SSID name.
good question. i'll pull the sd card out and check the txt out

to add, the 2 ssid's were causing the issue. you try to connect to one of them and it wouldn't bind to it.
