Raspberry3B+ Wifi
by lambo69 from LinuxQuestions.org on (#5H2DP)
Hello,
i freshly installed Slackware-Arm (-current, 32 bit). After installation, wifi does not show. In the previous installation (which i accidently completely messed up, therefore a fresh install) with -current on that RPi, it worked. Now, wifi-device doesn't show.

sarpi3-hacks-3.0-armv7-1_slackcurrent_20Apr21_sp1The deprecated rpi3-entry is not available in config.txt, wifi-device is not disabled
Code:root@xxx:~> cat /boot/config.txt|grep wifi
#dtoverlay=disable-wifiIn the previous installation, i had a udev-rule for wifi:
Code:root@xxx:~> cat /etc/udev/rules.d/70-persistent-net.rules
# net device ()
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="b8:27:eb:xx:xx:xx", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0"
# USB device 0x0424:0xec00 (usb)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="b8:27:eb:xx:xx:xx", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"Now, this rule doesn't seem to match. It doesn't make a difference, if this rule is present or not.
