View Full Version : [SOLVED] Wireless adapter not showing up (minimal install)

Hey all,

I have a laptop that I don't use anymore so I figured I would use it for trying to get used to the command line in Linux. The lspci line for my WiFi adapter is:


02:00.0 Network controller: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)

When I run iwconfig to see if my adapter is getting picked up I only get an output for the loopback interface and my Ethernet port. I installed the following packages which I thought would be enough to get it working:


b43-fwcutter, broadcom-sta-common and broadcom-sta-source

I was able to get it working in a regular Ubuntu installation, but it doesn't seem to pick it up in this install.

Does anyone have any tips/advice? I went with the minimal install because I wanted to see how lightweight I can get the OS.

Thanks!

Some new information as I did some additional digging and working:

I installed the bcmwl-modaliases and bcmwl-kernel-source packages and now it shows up. However when I run iwlist scan I get "Failed to read scan data : invalid argument"

Restarting networking does nothing to rectify this. I did some other commands like "iwlist eth1 txpower" and it shows it is transmitting at 24dBm, so the card appears to be working. I still cannot associate with an AP though.

Also, for what it's worth the light for WiFi is orange on my laptop (which generally means it is off, although it's apparently transmitting).

Please post output of
lsmod | grep "b43\|ssb\|wl"

And try
sudo modprobe wl

Thank you for the response. The output of the first command is:


wl 1959533 0
lib80211 5058 2 lib80211_crypt_tkip,wl

Sorry for the formatting, I am transcribing it from my laptop onto my desktop.

I did modprobe wl after that, and it seems to be repeating the same behavior.

Output of
sudo rfkill list

Here's the output of that command:


0: hp-wifi: Wireless LAN
Soft blocked: yes
Hard blocked: no

And you may have to
sudo apt-get install build-essential linux-headers-generic and
sudo apt-get build-dep linux then
sudo modprobe wl

Note: probably no need for doing these since we won't need to build from tar.gz if we can get your current wl driver going.

Ok, soft blocked is a problem.
sudo rfkill unblock all then
sudo modprobe wl

Yeah I have been enjoying it through Gnome for a while now, which I'm learning makes everything just so much easier. It worked in network manager, however I want to dive deeper into the CLI and see what else I can get going (a thread in the desktop environments forum inspired me), and network-manager wasn't so much an option then lol :-P

Thanks again!
