Neither ifconfig -a nor nmcli dev show display a wifi adapter on my Raspberry Pi4B.

After executing the following commands (which originally were listed in a related post (https://forums.raspberrypi.com/viewtopic.php?p=1515171):

rmmod brcmfmac

rmmod brcmutil

rmmod cfg80211

modprobe brcmfmac

both ifconfig -a and nmcli dev show list wlan0 as one of the items.

ifconfig allows me to 'up' the wlan0 interface.

However, when I run nmcli dev wifi rescan to see what networks I can connect to I get a message saying "Error: No Wi-Fi device found."

Also, after a reboot, wlan0 becomes invisible again and I have to execute all those commands again.

The OS is Oracle Linux.

Any suggestions?

  • Get another OS, or take your question to the U&L SE - someone there may have some experience with your OS. This is Raspberry Pi SE, and your question isn't related to the RPi hardware.

  • @Seamus yeah, not helpful. It's a RPi version of Oracle Linux, and the Wifi chip is certainly Raspberry... May 12, 2023 at 20:51
