fedora kde

I installed fedora kde plasma desktop on my Dell Latitude E6400. It runs great, but I can't get the wireless to work. I found this website

http://forum.fedoraforum.org/showthread.php?t=239922

and ran through the instructions but it still isn't working. The instructions say to run this command

lspci

and I get this

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

according to the chart I thought I would use the broadcom-wl,

when I run this

lsmod | sort

I get this

b43

so then I ran this

wget http://downloads.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2
tar xjf broadcom-wl-4.150.10.5.tar.bz2
cd broadcom-wl-4.150.10.5/driver      
su
b43-fwcutter -w /lib/firmware wl_apsta_mimo.o

but the wireless still doesn't work
any ideas on other things I could do to get the wireless working?

Did you follow the steps in the "Some things to try if it doesn't work" section?

1) Do you see the .fw files?
2) Is the b43 module still in lsmod?
3) Is wl or ndiswrapper in lsmod? (They should not be.)

"1) Do you see the .fw files?"

at   /lib/firmware/b43   there are 32 .fw files

"2) Is the b43 module still in lsmod?"

no idea how I would tell what mode it is in?

3) Is wl or ndiswrapper in lsmod? (They should not be.)

again, no idea how to tell?

For 2) and 3) the lsmod command "lists modules". It will display a long list, so it is common to omit lines that don't contain a specific search string using "grep." For example, if this command:
lsmod | grep xyz

Open in new window

produces no output, then you know that "xyz" is not in the output from "lsmod." So for 2), use
lsmod|grep b43

Open in new window

Note that spaces around the vertical bar are optional. For 3), try this command:
lsmod | grep ndis

Open in new window

Although you can grep for "wl" it is likely to find other strings, like "iwlwifi." It is still worth running it, but keep in mind that it will return "extra" data.

ok, so lsmod | grep b43 output was

b43                   387900     0
bcma                46142       1    b43
mac80211        589587     1    b43
cfg80211           474169    2    b43,mac80211
ssb                    66663      1    b43
mmc_core         116661    4    b43,ssb,sdhci,sdhci_pci

lsmod | grep ndis     didn't have any output

and   lsmod | grep wl   didn't have any output either.

That zero at the end of the b43 line means nothing is using the b43 module, which I think is the cause of your problem. Perhaps there are some useful errors in the logs. What is the output of this command?

sudo grep b43 /var/log/messages

My system doesn't use the b43 module, so I'm running out of ideas. Hopefully the errors that you post will help!

also, I've been looking around on the web, and found this

b43-fwcutter -l    which outputs this ( if it helps )

<driver>        <filename>              <microcode>
b43legacy       wl_apsta.o                   295.14
b43                 wl_apsta.o                   351.126
b43                wl_apsta_mimo.o         351.126
b43                wl_apsta_mimo.o         410.2160
b43                wl_apsta.o                    478.104
b43                wl_prebuilt.o                508.1084
b43                wl_apsta.o                    508.1107
b43                wl_apsta.o                    508.10872
b43                wl_apsta.o                    508.154
b43                wl_apsta.o                    644.1001
b43                wl_apsta.o                    666.2

sudo grep b43 /var/log/messages  outputs a lot of stuff, it looks like it goes through all those drivers that the b43-fwcutter -l   thing shows

at the end of each group of drivers it has this

 b43-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all instructions on this website.

one of the lines is  

[   11.993439] b43-phy0: Broadcom 4322 WLAN found (core revision 16)

and another is

 [   12.008191] b43-phy0: Found PHY: Analog 8, Type 4 (N), Revision 4

so it seems like it knows about the wireless hardware, and I thought I followed the directions, but I guess I got the wrong driver

Actually, that may have helped. We might have better luck following the instructions from kernel.org, which was linked in your error output.

So what is the output of the following command? This will help us determine if the b43 driver supports your hardware.
lspci -vnn -d 14e4:

so the  lspci -vnn -d 14e4:   yields this

"We might have better luck following the instructions from kernel.org"

I took your advice and went to this page, and followed those instructions. Now I have the wireless panel! and I can see my neighbors access points! But there's always something.
I don't see my AP because it is hidden, and I don't have an option to connect to a hidden network. I have a win7 work laptop that has the option to connect to hidden network and I can connect to my AP, so I know it's not my access point.
I was wondering, would there be a different wireless network panel I could try instead of the default that comes with KDE?

Probably. But that belongs in a new question on EE. If your original question has been answered, please mark this as closed/resolved, then open a new question.
