BTT since at least Buster provides in their vendor image a script to solve issues with the Wifi. And yes it in some conditions may have some issues with the network coming up, I even run in some issues with ethernet. They are solvable by restarting the networkdevice (either ethernet or wifi) with NetworkManager as well as with systemd-networkd. From history. The CB1 Buster vendor image from BTT as well as the vendor image for Bookworm, which actually you still can download at BTTs website contain a scrit that solves the issue by checking the network state all 5 seconds and in case restart the device. I personally used the vendor Buster image and the vendor Bookworm image on the CB1 to operate Openmediavault on it and believe me reliable Network is essential for a NAS. So yes those scripts work. I finally moved to the Armbian general Trixie image, just I was courious, but I took those scripts from bookworm with me. I even copied them to my "vault" of nice to have things for any device that needs reliable network. So I suggest to get yourself A vendor Bookworm image and loop mount it. No need to flash it. (if you are on Windoof, you need to flash it and have a look at the boot partition . At least I don't know a way to mount a partion inside a dd image of a blockdvice stored with sparse option.) Then have a look at the boot partion. There is a folder scripts. Interesing ther: /scripts/btt_init.sh /script/connect_wifi.sh what they do is, they start btt_init.sh in /etc/rc.local, which means always when the system boots at the very end of the boot process and btt init.sh starts a lot of those scripts in background mode, which meens if they have an endless loop, they never die. Only thing u need is connect_wifi.sh from there, so you can hash out all other or directly start connect_wifi.sh like they do.. #!/bin/bash # original BTT code, where the device name is set to a variable in the system.cfg: # cfg_file=/boot/system.cfg #enter the name of the wlandevice to check here: WLAN=wlan0 log_file=/boot/scripts/wifi.log IFS=\" sta_mount=0 wifi_path="/etc/NetworkManager/system-connections/" function connect_wifi() { # whether there is configured wifi in the history if [[ `sudo nmcli c s | grep wifi | awk '{ for(i=NF-2; i<=NF; i++){ $i="" }; print $0 }'` =~ "${WIFI_SSID}" ]] ; then set_wifi_path="${wifi_path}${WIFI_SSID}.nmconnection" if [[ -e ${set_wifi_path} ]]; then psk=`sudo cat ${set_wifi_path} | grep ^psk | awk -F '=' '{print $2}'` if [[ ${psk} == $WIFI_PASSWD ]]; then # both ssid & passwd matched. sys_now_wifi=`sudo nmcli c s --active | grep wlan0 | awk '{ for(i=NF-2; i<=NF; i++){ $i="" }; print $0 }' | awk '{t=length($0)}END{print substr($0, 0, t-3)}'` if [[ ${sys_now_wifi} != $WIFI_SSID ]]; then sudo nmcli c up ${WIFI_SSID} echo " ===> SSID & PSK is same as history, switch to: $WIFI_SSID " >> $log_file fi echo " ===> Now is: $WIFI_SSID, need not to do anything" >> $log_file return 0 else # psk don't match, remove and reconnect. sudo nmcli c delete ${WIFI_SSID} echo " ===> Remove all: $WIFI_SSID " >> $log_file fi else # remove all WIFI_SSID info (Theoretically, never execute to here). sudo nmcli c delete ${WIFI_SSID} echo " ===> Remove all: $WIFI_SSID " >> $log_file fi fi # connect to the new wifi if [[ `sudo nmcli device wifi list` =~ $WIFI_SSID ]] then if [[ ! `sudo nmcli dev wifi connect $WIFI_SSID password $WIFI_PASSWD ifname $wlan` =~ "successfully" ]] then echo " ===> Specify the WPA encryption method: $WIFI_SSID " >> $log_file sudo nmcli c modify $WIFI_SSID wifi-sec.key-mgmt wpa-psk sudo nmcli dev wifi connect $WIFI_SSID password $WIFI_PASSWD ifname $wlan fi else echo " ===> Hide wifi_ssid: $WIFI_SSID " >> $log_file sudo nmcli c add type wifi con-name $WIFI_SSID ifname $wlan ssid $WIFI_SSID sudo nmcli c modify $WIFI_SSID wifi-sec.key-mgmt wpa-psk wifi-sec.psk $WIFI_PASSWD sudo nmcli c up $WIFI_SSID fi } function Env_init() { exec 1> /dev/null # without check_interval set, we risk a 0 sleep = busy loop if [ !
