Image installation on RPi 1 B - WiFi not working

craindowl

Hello everyone I'm trying to install the latest Server image on an old Raspberry Pi 1 Model B.

Following the instruction on https://www.repetier-server.com/download-images/ the installation went well but I'm actually unable to connect the WiFi. I tried to setting up the WiFi connection from the web interface: I can see all the APs and select the one I want to connect to, I can establish the connection for a short time but in less than 10 seconds it disconnects automatically.

I tried also to manually override the connection adding the wpa_supplicant_wlan0.config file with the right settings paying attention to use a correct code editor such Atom but the results are always the same.

Until now I was using the same Raspberry Pi and WiFi USB adapter for the Repetier Server version installed on Raspberry Pi OS and everything worked fine.
 
I don't know what to do. Any suggestions?

Thank you.

Pi 1 has no wifi so it depend son the stick you have. Some can not scan network and be connected same time. See in the /boot folder there is a sample config for wpa supplicant. Enter your network credentials and and rename it to wpa_supplicant-wlan0.conf and reboot. Then server does not handle wifi at all and the config is set for wifi more or less the same as Raspbian does. That should normally work as then it depends to 100% on linux wifi handling.

I already tried to use the wpa_supplicant-wlan0.conf file with the same credentials that worked on Raspbian. It doesn't work. 

I also changed the power supply with one more powerful without any improvement.

If it can be helpful this is the iwconfig output when the WiFi is connected for a short time:

lo        no wireless extensions.

eth0      no wireless extensions.

I don't understand much: it seems that the wlan0 interface doesn't have any associated IPv4 but in my router's device list it appears with the static IPv4 I just previously assigned.

Thank you.

Agree, it shows that it is connected with TP-LINK_764F which is your router I assume.

Do you assign it the ip via dhcp? That is the assumed default normally. All you normally do on the route ris assign your wifis mac address 20:e2:16:00:52:ed the ip you want. Note that mac might be different to the one on Raspbian before - we use the hardware mac I think and no virtual one.

You should have a look at /var/log/syslog where linux logs the wifi attempts to connect. Maybe you see why it fails, e.g. wrong password.

wpa_supplicant-wlan0.conf is in /boot folder? I ask because we copy that file to /etc/wpa_supplicant overwriting old one. Eventually you need to reboot to make linux see new version.
