I don't get it.
I have gone through:
Yet no wireless networks are being listed in NetworkManager or wicd.
Do I need a /etc/init.d/net.wlan0 file or something?
Edit:
Output of --> wpa_supplicant -iwlan0 -Dwext -c/etc/wpa_supplicant/wpa_supplicant.conf --> is:
| Quote: | SIOCSIFFLAGS: No such device
Could not set interface 'wlan0' UP
ioctl[SIOCSIWAUTH]: Operation not supported
WEXT auth param 4 value 0x0 - ioctl[SIOCSIWAUTH]: Operation not supported
WEXT auth param 5 value 0x1 - l2_packet_receive - recvfrom: Network is down
ioctl[SIOCSIWSCAN]: Network is down
Failed to initiate AP scan. |

Please read this bug report. The b43 interface driver isn't all that it's cracked up to be. It is slow, has really bad throughput, and isn't stable.
As a seeming double-whammy, ndiswrapper setup under 2.6.24.x kernels is anything but consistent. If you are planning on using your wireless adapter with any frequency, move to 2.6.22.x version kernels. They support ndiswrapper and wpa_supplicant without problems.
Blessed be!

What are my alternatives then?

I'll try it and let you know what happens.
Thanks for the help.

When you downgrade, get 2.6.22.19 or 2.6.22-gentoo-r10. They are the latest and most secure of that line. Don't forget to run make oldconfig on your old .config file from your 2.6.24.x kernel. That way, you lose the stuff that doesn't exist in the older kernel version.
Good luck.
Blessed be!

I used the 2.6.22-gentoo-r10 kernel and followed the bcm4318 + ndiswrapper howto (take your pick: http://www.google.com/search?hl=en&q=ndiswrapper+bcm4318&btnG=Google+Search)... and now, finally, after a week of little sleep, all is well.
To think it was this simple--I don't know if I should laugh, cry, curl up in a fetal position or a combination of all three in remembrance of all the time I wasted.
But I'd be kidding myself if I thought jumping back into Gentoo after a several year break was going to be easy. I think I'll get started on the 3rd system install.
Anyway, thanks again, for all your help.
Merry meet, and merry part, and merry meet again.

I don't even want to tell you how long I tried to get my wireless going. It took me a week and a half of researching poorly-written documentation before I finally came upon the right combination of steps to get my wireless working. I settled on ndiswrapper just because it was the simplest option. Cut your firmware...I don't think so.
Since that time, I have tried using the kernel-based native drivers, but they always came up wanting, especially when it came to speed. I spent days trying to get the b43 driver to work in 2.6.24.2, only to find out that it was unstable, unreliable, and S-L-O-W. And while wireless networking is inherently slow, there's a big difference between a driver that can keep a fairly steady-state flow of 2-2.5 Mb/s, and one that can barely break 750 kb/s. The former is merely an inconvenience, the latter is a hair-pulling, cussing fit-having, pain in the tushy.
We are a circle, within a circle, with no beginning, and never-ending!
Blessed be!
Pappy
