BCM94311MCG Noob issues

Postby michael.marcos » Fri Aug 01, 2008 20:32

Sorry guys, but I have a pretty noobish question. I have never used Linux before, and I am making my way around it (hell, I just wrote a script two minutes ago... don't laugh dammit), but I am having issues with internet connectivity, as I hear are all the rage with this OS. I have a Compaq Presario F572US laptop that I just installed Sabayon 3.5 64-bit onto. My wireless adapter, as listed above, is the Broadcom BCM94311MCG - and something funky is going on with it. I have scoured the forums for advice, and I know what ndiswrapper is (barely know what it does). Here's what's happening:

The OS boots fine, the startup script I wrote works like a charm to configure KDE with running programs the way I want it, but it WILL NOT connect to the internet. Before I show the output from various shell commands, the strange thing is when I right-click the KNetworkManager icon, I see the wireless networks around me - but when trying to connect, it winds up at "Activation stage: configuring device" (28%) and then prompts me with "Connection Failure: Count not connect to the network Guest-HQ" (I'm at work trying to set this up). Also, mousing over each wireless network displays an ip of 172.17.10.71 - which I have zero idea about. I use my laptop just about everywhere I go, so I use configurations from WEP to WPA to unencrypted with Cisqo credential crap (the Guest-HQ I'm trying to connect to now). Here are the usual suspects for output. Let me know if you have any questions that will help answer my question (but keep in mind even simple tasks I have no clue how to do so please be clear when you have suggestions otherwise it probably won't help much). Thanks so much!

Yeah, also, forgot to mention that the wireless doesn't turn on off the bat - I have to log in as root and then right click the KNetworkManager icon and select Manually Configure, then click Apply (it asks if I want to restart network services), then I have to right-click the KNetworkManager icon and select Enable Wireless. Sorry if the labels for these menu items and buttons are a little shady, but I'm using my laptop dual booting and am using Windows just to access this forum. Thanks.

Even though you have correctly installed ndiswrapper, you are not using it. (see that alternative driver thing).

You will need to blacklist b43 and ssb

Or, alternatively, use b43 and blacklist ndiswrapper.

Please also post the output of

Code: Select all
ps aux | grep wpa

also forgot to mention, it appears that you may be having problems with wpa_supplicant. That is what I want to see with that command I sent you. If you get more than one entry for wpa_supplicant then we will need to do some acrobatics. :shock:
