So I just received the Edimax adapter, installed the 10.4 drivers, and connected to my router using the Edimax Wireless utility, but I'm only getting a self-assigned IP, I can't go on the internet and it's not seeing my network drives (both of which work fine over Ethernet). Any ideas?
Here's how it works with my Clamshell:
1) Start Edimax "Wireless Network Utility"; choose and connect to your wireless network; enter password for encrypted connection; save settings as profile
2) go to SystemSettings - Network-Pref-Pane; choose the "Ethernet (en2)" connection, which is the Edimax (you may also switch-off Airport, since you don't need/use it. On faster machines with "newer" Airport card you may connect to wifi with the edimax and share that connection via Airport, but I didn't test that yet...)
3) Choose the TCP/IP-settings for the "Ethernet(en2)" connection (DHCP with manual/automatic address etc.)
4) Now your clamshell ought to be connected to your network and the router. Otherwise modify IP-adresses or renew "DHCP-Lease"
That's it.

In the end, I've decided to purchase a second-hand 4th gen Airport Extreme for £35 to replace my Virgin Media Superhub (which I'll put in modem mode only). The router itself is frustrating enough, but this iBook wifi business has finally provided an incentive to supplement it with an Airport Extreme. Hopefully this will finally allow the iBook to connect!
I guess you may be fine with your old router too, but I also have some bad memories about tricky router settings that drove me mad.
You should give native MacOS9 a try too. Unfortunately to create a/more separate partition(s) you'll have to erase your drive. I've bought an external firewire400-housing to create an external bootable drive for SuperDuper!-images.
If you happen to attach an mSATA-drive make sure that you plan and create partitions before you start to rebuild the system. It can't be done later without loosing all data again.
And make sure to use an external firewire-connected disk (or another Tiger-PPC in Target-mode) for bootable images, since booting from USB might not work AFAIK)
If you also create partitions on that external firewire-connected drive, make sure, you don't do that with an intel-machine's resettings, since the standards for bootable drives has changed from PPC to intel-Macs.
As for native MacOS9 I had good fun trying to max-out the options and fit the clamshell to still existing network options, like VNC, FTP, webDAV, email, office etc. with the help and good advice of many nice folks here at PPC-MR-forum. Many Thanks!(
