Rasp pi 3B successfull install, cant connect to wifi
Hi!
Yesterday I got my repetier host (latest release) installed on SD card and fired it on rasp pi 3 B. On ehernet I see it on my lan all the-time and I can go to Wifi settings. In wifi setting I can see many wlans broadcasting in the are.
-I click on my wlan,
-type the password
-click connect
-tab changes back to Available wlan Router tab and blue message appears: "Unconnected"
I tried multiple working wifis, including my phone hotspot but problem is the same: "unconnected"
-I've tried saving wifi settings
It's a bit frustrating when I will not get a proper error message. Just Unconnected.
I got the system working yesterday for a while but had to shut it down for night. Today I canät get it working at all.

I unplugged ethernet and power. Plugged power and there it was on lan and working.
Unplugged the power again to move it 2meters to printers and now I cannot get it working again (disconnected printers, cam and all other devices).
I will report later how stable it is.
Also read our faq especially how to set up a file with fixed data, then that is always used to define wifi connection.
eventually also read /var/log/syslog to see what linux tries when connecting and why it undoes the connection.
I did not find your FAQ about setting up files for wifi connection. https://www.repetier-server.com/knowledgebase/
I tought I can set up wifi on the panel, which I succeeded of doing. I think I'm not getting something here?
I started to look at the log files and in the first start of today wifi did not work, moved it closer to the router and it started working with wifi. So I tried to replicate the problem and succeeded. Now in the panel (with eth0) is says "No WLAN adapter installed".
Could you tell me what am I looking for in logs. Somehow the logfiles are not in order. Timestamps. Some in the beginning of syslog are from today and some in the end are today. Inbetween there are logs from yesterday.
Thanks for your help.
same problem after update. had to install the old version
Innstaller 0.91.2 and all is ok again
The mac address for wlan changes on every reboot.
tried V15, V16, (if manually update from server (web interface v.91 to v.92 there seems to be no issues with WiFi) but fresh burned image to sd of v15 or v16 to a RPi B3+ not working
sudo rfkill unblock wifi
Please if you test first run
sudo rfkill list
and post it here to confirm that it was blocked before so we know that this is what is causing the wifi to not work as expected. Also
sudo nmcli dev
listed wlan0 as unavailable before I unblocked wifi. Hope that also works you.
0 wlan phy0 unblocked unblocked
send: sudo nmcli dev
eth0 connected
wlan0 unavailable
No WLan
sudo rfkill unblock wifi
changed anything especially sudo nmcli dev should go to disconnected or connected afterwards.
denyinterfaces wlan0
you need to add. Also have set NetworkManager.conf property managed to true but not sure if that is necessary. Anyhow in my tests so far it seems to work now.
(This information is written into the file /etc/wpa_suppicant/wpa_supplicant.conf)
Thanks for the NetworkManager hint. Was already wondering who is responsible for changes. After some research it seems that the default behaviour changed with newer NetworkManager version. /etc/NetworkManager.conf with
[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=true
[device]
wifi.scan-rand-mac-address=no
[connection]
wifi.cloned-mac-address=permanent
ethernet.cloned-mac-address=permanent
Seems to solve the problem giving a stable mac address back. AT least it survived reboot and several restarts of NetworkManager without changing the mac after it changed to the permanent mac.
So I hope I'm now close to get wifi back stable in buster.
as soon as first time on, the AP menu for region will not load, just switch languages, and it loads correctly, then you can choose the Region, for it to let you to accept clients, or connect to a WiFi network
