I've just installed Gentoo on my very first Mac- a Powerbook G3 Wallstreet II. Now that world is up to date, my next order of business is to get wireless working. Since this doesn't have it built in, I am using my trusty D-link DWL-G650, which has served me well in the past. Like many that are new to Gentoo/PPC, all of my experience has been on x86- with regard to laptops, a Compaq Armada 7360DMT Pentium-MMX 200Mhz. This is the laptop I've used the D-link card with for over a year now, never with any problems.

Of course, this is all new territory.

I've emerged madwifi-ng-0.9.3.1, madwifi-ng-tools-0.9.3.1, and wireless-tools-28. (all current stable as of 7/29/2007). When I insert the card, dmesg shows all the expected messages from pccard, ath_hal, PCI, wifi0. I run iwconfig to set essid and key for my AP, then dhcpcd. The card appears to associate (one led, then the other, flash while it searches for an address, then both flash simultaneously), but dhcpcd exits with a timeout and no address is assigned. The card does not appear in the client list in the AP either.

Since this has always 'just worked', I have no idea where to begin troubleshooting this. Any help greatly appreciated.

It's tough to say. Even though the dmesg looks normal, can you please give us the relevant sections?

Well, that all looks fine. If DHCP times out, does a manual configuration give you a working connection? If you manually run dhcpcd with verbose debugging, what does it say?

I feel like a complete idiot.

Had all sorts of debug info prepared, then a light clicked on. Got out the other laptop to verify.
Had 2 numbers (17, not 71) flipped in the WEP key.

Nevermind. :oops:

Suprised, though, nothing tipped this off. Verbose output from dhcpcd -d just kept repeating "Sending DHCP_DISCOVER". No mention of scrambled packets or anything. Also, apparently the "Associated" blinking just means it's found the AP, not established a valid connection.

Hopefully someone else can learn from this. Thanks, JoseJX, for helping, though. I'll try to think things through more thoroughly next time (got some google scouring to do first)

No worries. :) Glad you got it working!
