 Posted: Fri Aug 29, 2008 6:54 pm Post subject: Wireless--can't scan/associate (Broadcom card)[sorta-solved] |
 |
|
Update: After a bunch of messing around, downgrading the kernel to 2.6.25 because I needed vmware-server to work, etc etc ad nauseum, the wireless card has suddenly decided to successfully iwlist scan a network other than mine. I still don't know why, what changed, or why it won't work on my home network, but it looks like it probably isn't a driver problem after all.
I tried to get the wireless card on my laptop up and running back in May, got nowhere, and dropped it for a while. Now I'm trying again.
The card is a Broadcom 4311 (rev 02), and the laptop is a HP Pavilion dv6607. The b43 driver from the kernel appears to initialize the card correctly (the little blue LED even comes on, and the contents of dmesg indicate no show-stopping errors that I can identify) but I cannot scan or connect to my network using the card, even though the wireless router/access point is located not three feet away. I know the SSID for the network, the router's admin utility indicates it is being broadcast, and there is no security running on the network (and won't be until I get this working). I have tried both wireless-tools and wpa_supplicant. I have tried setting the SSID specifically as well as scanning. I have also tried ndiswrapper, and didn't get even as far with it as I did with b43 (I suppose there's a possibility I was using the wrong driver--I'm running a 64-bit system and 64-bit XP drivers seem to be hard to come by--but . . .) I haven't tried sacrificing a rubber chicken to the network gods while standing on my head in the shower at midnight, but that's mainly because I don't have a rubber chicken. ;P

I understand the "ioctl[SIOCSIWAUTH]: Operation not supported" to be harmless, and I can't see anything else wrong except the fact that this Is Not Working.
Help?

I have one of these in my main machine (which I'm not on at the moment). I've been trying the b43* module for a while now. I even bumped the kernel up to 2.4.26 to see if it was any better. Well... I still went back to ndiswrapper. I haven't had a single issue using ndiswrapper with that card. I'm sorry that I can't sit here right now and give you the exact version of the firmware you'll need since I'm on a Windows box at work...
I can get to typing it out here later tonight from my machine so I can give exact versions of things.

You forgot to be singing Louie Armstrong's "It's A Wonderful World" while doing so. That may also produce the issue you're seeing.
