wlan0 device missing

Question

I can't seem to get my wifi working and I feel i've exhausted google's search capabilities.

Here is the output of lspci for the device

As you can see, there is no kernel driver associated with it, and I have no idea how to get one associated with it. I'm using debian 7.8. I know that the correct kernel driver for it is the wl module, which I have installed but for some reason it doesn't associate with that network card.

here is modprobe debug output:

Is there something like /lib/modules/3.2.0-4-amd64/modules.alias that I'm supposed to update?

Hmmm interesting development... they are already blacklisted... Try the Arch Route, and let me know the outcome. Also, probably a stupid question, but you are using a dkms enabled kernel, right? — eyoung100, Commented Jun 10, 2015 at 21:57

I hate to tell you this, but this card is not supported, by the default driver. Under normal circumstances, all Broadcom cards are supported by the b43/b43legacy drivers on the Linux Wireless Project, but as you can see on the Supported Hardware list, the entry for 14e4:43b1 shows:

+================================================+
| ID     Support Name    Modes      PHY Alternate|
+================================================+
| 14e4:43b1 no  BCM4352 a/b/g/n/ac  AC (r3) wl   |                                             |                                                |
+================================================+

The Alternate Driver is listed as wl, which you've found also. Reading:

AskUbuntu Post - How can I install Broadcom Wireless Adapter BCM4352 802.11ac PCID [14e4:43b1] (rev 03) on fresh install of Ubuntu 14.10 (Utopic Unicorn)?. The driver is no longer listed on the Linux Wireless Project Page, so that's as close as I can get you, but that should start you on the right path. Have you tried the modprobe listed in the answer?

Since Ubuntu is a Debian derivative, you should be able to try the apt install listed in chilli555's answer. If this works, you're in luck

Interesting thought: The map search yielded CN - China, but I live in the USA. HMMM.

Since your output has no frequency ranges listed, I wonder if we need to blacklist a module?? Read the Troubleshooting section in The Broadcom Wireless Arch Wiki, and then try Blacklisting the b43, and the ssb driver, along with the bcma and bcrm80211(>=kernel-3.3.1) drivers, and lastly, does this card work on Arch? Fire up a LiveCD, and see if tools like ping work after booting... If it works in Arch, but not in Debian, then Debian is misconfigured, but if it works in neither chances are you've got a wonky or unsupported chipset.

Thanks, I installed the debian equivalent of that module but it still doesn't work, is there any way I can dive deeper into the problem to check what the wl module I downloaded supports or how I associate it with my device? — Salgar, Commented Jun 9, 2015 at 17:10
What does lsmod | grep wl return? Also dmesg | grep net? — eyoung100, Commented Jun 9, 2015 at 17:12
Edited to add the lsmod output, the dmesg grep prints nothing — Salgar, Commented Jun 10, 2015 at 21:01
From your lsmod output the driver is loading, but driver wl is being used by 0 items. What's the output of dmesg | grep wl and dmesg | grep cfg80211 and dmesg | grep addr? Also, have you tried depmod -a` and a reboot? — eyoung100, Commented Jun 10, 2015 at 21:12
sorry my dmesg was full of useless UFW output, I restarted and have edited my answer with the output of the previous and all of the above dmesg outputs. — Salgar, Commented Jun 10, 2015 at 21:21
