Can't bring up wlan0

[trustnt]

I'm using a Raspberry Pi 3 Model B and using the aarch64 image, the kernel version is 5.16.1-1-aarch64-ARCH.

This is the command I used to bring it up

Code: Select all

sudo ip link set dev wlan0 up

but when I look at the output of

Code: Select all

ip a

this is the output for wlan0, it still says it's down and I can't use it with hostapd

Code: Select all

wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000

Just joined the forum to report this + video not being detected properly any longer, but then on my fresh install (see below), WiFi is working....

I did a fresh install and everything works fine with the software that comes with installation tarball, but upon updating is when I get problems. WiFi, however, works with the fresh install + update but video detection still does not.

Edit: Unfortunately I had cleared my package cache not long ago so I don't have much earlier packages to test with downgrading

@trustnt - Updates to the kernel you're running have been made to accept compressed firmware files have been pushed since you posted. Update your system.

@mactroneng - No idea what hardware/kernel you're running. Knee-jerk advice is same same as I gave above.

I don't know about linux-aarch64 but linux-rpi should work...
