BCM4322 Broadcom card can't use WEP

dmyersturnbull · #1 11th July 2009, 03:30 AM

Hey, all.

I have a Dell-made, Broadcom-based wireless card, BCM4322. I'm using Broadcom's proprietary drivers from RPM Fusion.

Code:

lspci | grep -i broadcom
09:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5784M Gigabit Ethernet PCIe (rev 10)
0c:00.0 Network controller: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)

Since installing F11, I can no longer connect to WEP-secured wireless. When I use automatic IP settings, the connection simply times out. When I specify an IP, Netmask, Gateway, and DNS server, NetworkManager thinks the connection properly established, but any pings time out, even when I don't specify a hostname (just an IP address). I can connect to (and use) unencrypted wireless. I haven't tried other encryption schemes. The WEP index is 1 and it's non-authenticated (open). I've been playing with the settings for over a week now with no success.

Thanks,
Douglas

If you can use b43, I suggest doing so. http://linuxwireless.org/en/users/Drivers/b43

I had a similar issue, which I couldn't figure out, but I had just switched to b43, and since I commonly configure my own kernels, don't feel like installing the same crap over and over. Since b43 is built into the kernel, with the exception of the actual firmware, it's easier IMHO. All you need to do is copy the files into /lib/firmware(If you follow the directions it'll automate it), then you've got wireless for life.

Hey,

Thanks for the reply.

Unfortunately, it seems b43 is not compatible with my card:
BCM 4322 802.11a/b/g/n (Has PCI-ID 0x432B) - This device has an N Phy. There is no support for any Draft 802.11n features. We are working on it.

Hello dmyersturnbull

The 4322 usually works pretty well with the broadcom-wl packages from rpmfusion.

I think we do need to consider though whether the compatibility problem is WEP itself, authentication in general or some problem between you card and the driver.

The only way to do that is to experiment a bit.

Any chance you could switch the encryption off on your router for a short while? Or preferably up it to WPA? That would at least answer one question.

Thanks for the reply.

Unfortunately, too many people need this router—I can't change the settings without interfering.
I tried using b43 off of that website, but the problem persisted.

I think my initial post was erroneous: I think I had been using b43. In F10, I was using this, which worked perfectly. I now remember why I didn't use it in F11: it won't compile with F11 and GCC 4.4.0-4.

Sorry if that was too long.

How can I compile that? I'll try downloading an older version of gcc, though I don't see anything in the changelog that could have affected that.

Thanks for your help so far!

The various patches offered for 2.6.29 always failed on at least one hunk—consistently.

Fortunately, however… I got it working! I'm using b43 from RPM Fusion (and have been using it since I installed F11).

The issue was that the passphrase was not being used to generate the correct key. I changed the passphrase to ascertain, and it again—didn't work. My router provides a web interface, which I used to find the 64-bit key. I changed NetworkManager's settings to use that, and it worked. My card, b43 driver, WEP, and router now get along.

Thanks for your help.

Hello dmyersturnbull

Pleased to hear that you have come to a successful conclusion.

Something to remember, as the b43 driver site clearly says that the 4322 is not supported by their driver.

I gather earlier that you were trying to compile the broadcom-wl driver from source. Just for reference, in case you ever need to try again, that particular driver is also available from rpmfusion.
