Wifi Connection not working since Update
I just ran a full update on my V-Minion and now I am unable to connect to a new Wifi. The only way to interact with the machine atm is Klipperscreen that, when going to the network menu, states that it failed to detect network manager. Before when it was still connected to the old wifi I was at least still able to connect via ssh and start the networkmanager service manually, which led to me being able to see the list of available wifi networks but when i then tried to access the new Wifi network I got an error saying that it doesnt have permission to connect to it.
Now I am locked out of the machine because it is not connected to any wifi and i am unable to reconnect it since i cannot use the klipperscreen network page.
It's the stock setup with Raspi 3A+ so no ethernet port as an alternative.
What possibilities do i have?

That was misleading, klipper screen wasn't dead it just wasn't working and showing an error on the Homescreen while also for some reason klipper could not connect to the printer. I disconnected the screen and everything worked fine throughout the workshop today. 🥰
Next time I come around to doing work on the printer I will Update everything in the correct order. Thanks for the help again.
Btw who is responsible for theRatOS installation manual on the Ratrig site?
I think I have some inputs on how it could be made clearer and easier to follow....

This is my network screen atm
Sounds similar to other reports, have you found anything searching this discord for "Network Manager"?
yes, people report similar errors on here and on github issues in klipper and klipperscreen, but the solutions are not applicable since i have no way of communicating with the pi.
it is also strange that the pi doesnt open ratos although there is no wifi connection
okay I just had the idea to disconnect the DSI Touchscreen and now I was able to load the webinterface. So the Printer did connect to Wifi on it's on without a connected screen
Is it possible to roll back KlipperScreen to a previous stable version?
use the configurator to setup your wifi.
Yeah via ssh, you'd just need to find the commit before they dropped support for everything but NetworkManager.
But honestly you shouldn't be using that network panel in the first place
IT fucks over the network config (which is why you're locked out currently).
i just read one of your comments to someone with the same issue, where it wasnt clear how a screen could affect wifi, this is exactly what i just experienced.
could it be that by disconnecting the screen, klipperscreen doesnt try to load network manager and thus it doesnt fuck with the setttings?
Network manager doesn't work on RatOS (and is disabled). It doesn't screw over the config before you use it to join a wifi network, that's when it breaks the setup (it would connect to the wifi, but the hotspot functionality would be broken and the RatOS configurator wifi changes would no longer have any effect). In it's current form it'll just show you an error screen because NetworkManager isn't available.
okay, i will try to reconnect the screen than and see what happens. what is the safest way to add another wifi network?
I am transporting the minions quite a lot for Workshops with children and need this functionality to have an onsite network
okay i just verified, it doesnt connect to wifi when the screen is connected. Could un- and reinstalling klipperscreen solve this issue?
okay, i will try to reconnect the screen than and see what happens.Won't do anything
what is the safest way to add another wifi network?Depends on exactly what klipperscreen did to the configuration. Last time i checked (the old code, before they dropped support for everything), it replaced the wpa-supplicant file in
/etc/wpa_supplicant/ killing the symlink to the /boot/ratos-wpa-supplicant' which is the only way you could manually add a network without a linux machine or ssh access.
I am transporting the minions quite a lot for Workshops with children and need this functionality to have an onsite networkThat's what the RatOS hotspot is for... It comes up automatically when it can't connect to the configured wifi. But you broke that with the klipperscreen network config 😄
Could un- and reinstalling klipperscreen solve this issue?How are you going to do that without a connection to the machine? (and no it wouldn't). If you can't SSH into it, you're shit out of luck. Unless you can quit klipperscreen once it's started, then you could hook up a keyboard and mouse, and then add the network that way. But really what you should do is reinstall so you get the proper RatOS functionality back. (i'd suggest 2.1-RC1 now that you're at it)
before, disconnecting the screen, and rebooting led to it reconnecting to the old the wifi which i could also connect to
Before what?
Disconnecting the screen... I don't understand how that changes anything, the network configuration isn't handled by klipperscreen, it just overwrites config files.
i dont understand it either, i have tried that now 2 times and the first time it helped now it did nothing.
It is now spawing the RatOs hotspot though, but i cant seem to connect with raspberry as pw
The best thing you could do is to hook at up to your router via Ethernet, download your printer.cfg in case you have some custom stuff on there (like i don't know, IS settings, z_offset and what have we), then reinstall.
It is now spawing the RatOs hotspot thoughOh good!
but i cant seem to connect with raspberry as pw... i've got nothing. I don't see how or why klipperscreen would change that.
theres no ethernet on stock Raspi 3A+ ðŸ˜
i think i have to reflash, F#CK 😢
I just wanted to check my 2 printers for the Workshop tomorrow and now it will become a nightshift
oh right yeah, you'd need a dongle
i think i have to reflash, F#CKIt's not that bad, really. Only thing that sucks is flashing the SKR2 because you need access to the SD card or DFU. The new configurator should have you up and running in no time It's a really bad idea updating things right before you need it There are too many third party things that i don't control but if you updated everything and it still runs the SKR2 should be up to date (at least enough to work)
I will find that out soon. I just didnt want to dissasemble it again now since its all in @Squirrelbrain 's electronics box, but yeah thats what you get for updating before match day
now i know that klipperscreen network settings are a no go
