Unable to create wireless device

[rraj]

Hi

Facing issues trying to create wireless device: ifconfig wlan0 create wlandev iwm0.

ifconfig: SIOCIFCREATE2 (wlan0): Device not configured

.

How to proceed?

Thanks

Do you actually have an iwm(4) device? What does sysctl net.wlan.devices output?

Hi SirDice

I actually used wi-fi previously! The command gave output : net.wlan.devices

Thanks

The command gave output : net.wlan.devices

Then you don't have a iwm(4) (iwm0) interface, or somehow it's not being detected. Maybe switched off? Some laptops have a switch that disables radios (Wifi/Bluetooth).

Hi

The issue happened after a major version release from 14.3 to 15.0 did not complete. I then rolled back the upgrade. After a subsequent restart facing this issue.

I do not have switch working for wi-fi, from ever since i purchased the laptop.

Thanks

Which interface is the wifi device connected to on your machine?

USB, then: usbconfig

PCIe, then: pciconf -lv | grep -B3 network

Hi T-Daemon

PCIe the command yields:

pciconf: ioctl(PCIOCGETCONF): Operation not permitted

.

Thanks

I was playing with WiFi a few months ago and documented it at

If you read it, there might be some steps and procedures to help you with troubleshooting your wifi setup.

First time I see such an error massage from pciconf(8). Was the command executed as user or "root"?

What does freebsd-version -kru show?

Hi

The command pciconf -lv was executed as root. Now even multiuser boot option boots in single user mode.

The freebsd version is 14.3.

Hi david.pasek

My wireless adapter is not identified, even may be not detected, what to do in such a scenario?

Thanks

Now even multiuser boot option boots in single user mode.

Is this still the case or is the system booting in multi-user mode?

The freebsd version is 14.3.

What exactly does freebsd-verison -kru show (-k : installed kernel, -r : running kernel, -u : installed userland).

Hi T-Daemon

Multiuser boot still acts as single user boot!

freebsd-version is 14.3 release p3 for k & r, whereas 14.3 release p4 for u.

Thanks

Post the error (there's a reason why it drops back to single user mode).

Hi SirDice

Sorry for being cryptic but multiuser boots in as root by default, similar to what is in single user mode! Since network is not there can’t post the error.

Anything else that i may try.

P.S-Working in command line mode, GUI not working.

Thanks

If it correctly boots to multiuser mode you will eventually get a "Login:" prompt. If there's an error (bad fstab, syntax error in rc.conf) it will break off the boot process, and you get a question "Enter full pathname or RETURN for /bin/sh:". Pressing ENTER will drop you in single user mode at a root prompt. Is that what you're seeing? Just above that question there's an error telling you what went wrong.

Edit: I normally hate pictures of text, but if you can take a picture with your phone that'll be good.

Hi SirDice

Sorry for delay in reply. Yes i am getting the question, asking press enter to drop at root prompt.

Attaching picture of error screen.

Tried fsck -y,
mount -u /
mount -a -t ufs
swapon -a, no luck.

Thanks
