I really need to get gentoo running with internet on my g4 laptop for my work, I have the 2006 ppc install cd and have got as far in the handbook as installing portage. I only have access to wireless internet so getting it going with ethernet isn't possible. I do have working wireless in my OS X install so I can download and burn things on CD/DVD with that.

I've tried testing the internet connection with ping www.google.com, and run ifconfig which just lists eth0 (presumably the ethernet card)

I could just install from the snapshots of course but I'm assuming that won't give me a working wireless connection.

Is there any easy way I can get my airport extreme card working? Will it work straight away from the 2007.0 install cd or is it not in there? If not is there any way I can use my os x internet connection to download the necessary drivers and install them?

I've also noticed that when i do lspci as mentioned in the native airport extreme drivers thread i get 4320, which it says isn't supported yet. Is it possible my g4 powerbook has one of those cards? All I could find about it on the OS X side was:

Wireless Card Type: AirPort Extreme
Wireless Card Locale: Worldwide
Wireless Card Firmware Version: 405.1 (3.90.34.0.p18)

If all else fails can I just go out and buy a cheap usb wireless dongle and use that or will gentoo not recognise it?

You need kernel sources, bcm43xx-fwcutter and a firmware file. The cutter and the firmware are not on the cd, so you can't do this with only a cd. If you get the sources for the cutter and the firmware file using osx, you should be able to build a kernel that includes the bcm43xx driver and get it to work with the firmware. Oh, there's also a patch from some Larry you need :)

Thank you! I used the bcm43xx-fwcutter sources and it worked, although it turns out the option in the kernel menuconfig for bcm43xx is hidden until you turn on softmac so it took me a while to get it going :)

It now recognises my wireless network and iwconfig showed it connected with a strength of 75/100, but for some reason i just get destination unreachable if i try and ping my gateway (192.168.1.1, the same as it is set to on os x) or the dns servers. as far as i can tell i have set up /etc/conf.d/net and /etc/conf.d/wireless correctly so I can't figure out why it isnt working. Does anyone have any suggestions?

I've set config_eth1 to my ip, routes_eth1 to the gateway as it is on os x, set up key_ESSID and eth1 essid properly and set the dns servers...

And is there a way of doing modprobe bcm43xx automatically at boot up?
