I got my wireless router set up and running! I also picked up a wireless bridge to connect the old iBook wirelessly, err… semi-wirelessly. The iBook is still using an ethernet cable to connect to the bridge, but from there it's wireless!
I'm now good to go in a couple days when my Tivo arrives! Also, once I get my work laptop in a couple weeks I'll have truly wireless access! In the meantime I can pull the ethernet cable I used to use for my iBook out of the wall and patch the hole up.
