I have a DELL Laptop and I just installed SUSE Desktop on it. I am able to connect the machine to the web using wired connection but not able to connect wireless. I am not able to see the bcm4313 wireless by using both Netmanager and Ifup.

0a:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5761 Gigabit Ethernet PCIe (rev 10)
--------------------------------------------------------------------------------------------------------------------------------------------------------------------

I am able to see the Ethernet Controller on my Network Settings (both Network Manager and ifup), but I am not able to see the BCM4313.

I had followed the document in http://www.broadcom.com/docs/linux_sta/README.txt
Broadcom Linux hybrid wireless driver
Version 5.100.82.1XX

but I was not able to see any progress. Not sure if I am messing something up.

Currently i see

Not sure what the "0" stands for here.

I realize here that there are TWO wireless drivers - look at the last line "Kernel modules: wl, bcma". I had to blacklist the bcma driver ...and now atleast the wireless option is showing up...but I will have to configure that using NetManager.

Well now it is fixed, the "Wireless Network Connection " was grayed out in NetManager in the bottom right corner of my screen icon. Simple fix-

1. Make sure your wireless switch is turned on. My computer had a switch. Some comps have (Cntrl+F2)
2. Right click on the icon and enable wireless....Viola!!! I can see all wireless connections near my laptop. I had configured my wireless router setting and so was able to connect to it and go wireless

Hope it helps someone....
