I think I have all relevant information in the link below, please let me know if there's anything you can think of, or some other useful information I should display. I have got this card working on arch/other distros before, but it's a struggle every time. Thanks

Start with the b43-firmware.
I may have to CONSOLE you about your usage of ridiculously easy graphical interfaces...

That card is supported both by b43 and brcmfmac. I would use either of those before wl.

I agree with the above, and being I have a different wifi card, and still had the problem, this helped me.
[joey@joey ~]$ sudo pacman -R networkmanager
*next step may be extra and not needed, again worked for me*
[joey@joey ~]$ sudo pacman -Sc
Finally
[joey@joey ~]$ sudo pacman -S networkmanager
Also, make sure you have a alternate way to connect to the internet. As always, your milage may vary.
Hope it helps

Thanks for the replies everyone.
I switched to the b43 driver, at the advice of Trilby. Now, I have been able to see wireless networks, but intermittently. I will run a scan with iwlist, or networkmanager, and will see networks, but running that same scan 2 minutes later and no dice. Not sure of the cause of the intermittent behaviour. I have never had wicd see a network, but I dont know if thats something with my card and wicd, or just a biproduct of the intermittent results.
Also, http://wireless.kernel.org/en/users/Dri … _b43legacy lists my card as being only partially supported, which is why I went with broadcom-wl initially. I didn't see where I could find what wasn't supported with this card.
Here are another round of scans/logs/information. Appreciate any further advice

Thanks, sorry for information overload, but more is probably better than less. Let me know. All comments appreciated.
On a semi-related note, anyone have recommendations for a wireless-n card that works out of the box? PCI preferred, PCI-e and usb also accepted. Lol.

Wlan0 is up:
3: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DORMANT qlen 1000
link/ether c0:3f:0e:bd:89:df brd ff:ff:ff:ff:ff:ff
The UP/DOWN inside the angled brackets is for the interface. The second UP/DOWN after state is for an actual connection. So the interface is up, but just not connected to anything yet. So the next steps are iwlist scan, then to associate with one of the scanned networks. What have you done to attempt to associate with your network?
I'm not familiar with that last error you are reporting, but have you removed everything related to wl? Have you rmmod the module and/or removed it from modprobe.conf and rebooted?

It seems like wl was a pain to remove, and if left in there would cause further problems with b43-firmware. It was because o the blacklisting that wl does.

You should have your network listed in networkmanager. Try connecting with that first. iwlist scan might not always return a result as the signal strength is only about 50%.

This doesn't make any sense. Using network manager will not solve any driver issues. And network manager will not see anything iwlist doesn't. Network manager is just a convenient wrapper for the iwlist and ip tools.

Well, the network seems to be working. It has demonstrated the ability to use the radio and do a site survey.
DMA means Direct Memory Access. DMA allows peripherals to take control of the bus and transfer data to and from main memory without the processor having to move data byte by byte. It is much faster and, if the processor does not need anything on the bus, can continue processing while the transfer. PIO (Programmed Input/Output) means the processor has to do the heavy lifting.

Let's see here.
rmmod wl
rmmod: ERROR: Module wl is not currently loaded
There is nothing in modprobe.conf, nor any other files in /etc/modprobe.d/
I used pacman to uninstall the broadcom-wl driver I had obtained from the AUR. AFAIK it is entirely gone.
This is the network I would like to connect to, ArchWifi. It is an unsecured network, but does have mac address filtering enabled. My mac address is on the approved list. So here is my process.
sudo iwlist scan

next step, according to wiki
sudo iwconfig wlan0 essid ArchWifi
This returns a prompt.
So to check if im connected, I run sudo iwconfig wlan0
wlan0 IEEE 802.11bg ESSID:"ArchWifi"
Mode:Managed Access Point: Not-Associated Tx-Power=27 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
So this has my essid set correctly, but access point is not associated? Anywho.
Running dhcpcd at this point, all i see for wlan0 is waiting for carrier. Never grabs an IP.
NetworkManager also sees networks, I click on ArchWifi, and nothing happens. Could network manager be interfering somehow with my trying to connect manually? I am using gnome as a DE, in case that has some importance with applets or somesuch. The reason I bring that up is this thread http://ubuntuforums.org/showthread.php? … bfb96908e5 , although it is old, and for a different distro.
That's everything important I can think of to mention right now. I appreciate the continued patience, thanks all.

It says that your network has encryption... so you need to read through those instructions more closely. In general, iwconfig has been succeeded by iw, though the use of either of those tools is still typically okay... as long as you have no security.

What am I missing that leads you do that conclusion?
Encryption key:off
That means it's an open network, right?

Whoops. I could have sworn it said "on". Guess I had better have my eyes checked!
Edit: I see now. I was looking at post #5.

I was speaking by experience over there. I have had WLANs with weak signals dissappear from the iwlist scan results when they still are present in the networkmanager list.
I think this should clarify what I was trying to point out:
NetworkManager also sees networks

No real progress to mention. Running dmesg -w while trying to connect gives me
[13820.876993] wlan0: authenticate with 22:10:7a:06:fa:ac

the mac address is correct the ArchWifi, the unsecured network, and it does try and connect, but times out. Interesting, but I don't know whats causing the timeout.
Also, by launching cinnamon-settings through terminal, and trying to connect to a network, I get this error. Or well, warning.

Unsure what else to try. Thanks

My suggestion:
turn off MAC address filtering on the router
turn off encryption
boot into command prompt
then run iwconfig wlan0 essid Archwifi
check if it associates fine. You need to remove all possible sources of issues.. atm, there are some many factors - gnome, networkmanager, mac filtering....
