File /opt/wifi.sh not found, mismatching with the setup guide

[rodaciri]

Steps to Reproduce

1. Followed the instructions in the WiFi setup guide at this section.
2. After writing the ssid and password into the "/etc/wpa_supplicant.conf" file, I tried to run the command /opt/wifi.sh.
3. But I got a "not found" message.
4. Then, doing stat /opt/wifi.sh I confirmed that file doesnt exist.
5. Finally I noticed the "/opt" directory is empty.

Additional Information

• I tested it out with images:20241129 and 20241220.

Please let me know if there is another way to set up the wifi. BTW for some reason internet connection via ETH is not working either.

after editing /etc/wpa_supplicant.conf reboot

you can then ssh into the device over wifi

Hi, I have the same problem and rebooting the device doesn't solve it. I have a Lichee RV Nano as well. @Neutree I don't understand your answer. What should I do with it ?

[lesept777]

I created the files /boot/wifi.ssid and /boot/wifi.pass I executed /etc/init.d/S30wifi restart but not sure it worked. Here is what I get, and the console seems frozen

kill: you need to specify whom to kill kill: you need to specify whom to kill Your kernel has module support but you don't have modinfo installed. It is highly recommended to install modinfo (typically from kmod). Warning: driver detection without modinfo may yield inaccurate results.

Requested device "wlan0mon" does not exist. Run /usr/sbin/airmon-ng without any arguments to see available interfaces wifi mode: sta ssid: lesept wifi.pass: *** Successfully initialized wpa_supplicant nl80211: kernel reports: Registration to specific type not supported

Not sure what to do next...

your steps and log are all right, but just dhcp not got IP in some how

(maybe your AP encrypt method etc. you can set /boot/wifi.* files and reboot,

• if connect AP successfully, maybe S30wifi have bug;
• if also can't got IP, maybe AP's parameters not match, you can create your own /boot/wpa_supplicant.conf add more parameters and restart S30wifi or reboot.(wpa_supplicant.conf format follow standard linux wpa_supplicant's config file format)

I found a way to connect the board to the Wifi. I seems that the /etc/wpa_supplicant.conf that is created is not correct, so I made a shell scruipt to correct this:

#!/bin/sh
# Create wifi connexion
killall wpa_supplicant
rm /etc/wpa_supplicant.conf
touch /etc/wpa_supplicant.conf
wpa_passphrase <ssid1> <pass_for_ssid1> > /etc/wpa_supplicant.conf
wpa_passphrase <ssid2> <pass_for_ssid2>  >> /etc/wpa_supplicant.conf
awk '!/#psk*/' /etc/wpa_supplicant.conf  > temp
rm /etc/wpa_supplicant.conf
mv temp /etc/wpa_supplicant.conf
wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -B

Executing this shell enables the board to connect to one of the listed wifi ssid. It can certainly be improved... I hope this helps
