Using a wireless access point?

If you get a Linksys WRT54G (or WRT54GS) and install one of the
firmware "upgrades" from http://www.sveasoft.com/, the wireless
configuration page will have a new option called "client mode". This
configures the router as a wireless client and thus function as a
wireless bridge.

This is what I am using for my TiVo and it works great.

I paid the $25/year fee so I could use the "Alchemy" releases, but the
free "Satori" releases also support client mode. The technical
details differ significantly, though. In Satori, enabling "client
mode" configures the router as a bridge. For a variety of reasons
this does not always work, especially if you have more than one
machine behind the bridge (which I do). In Alchemy, enabling "client
mode" causes the wireless uplink to be treated exactly like the WAN
interface. This is more reliable and efficient, but it also firewalls
off my TiVo from the rest of my network, which happens to be what I
want.

The WRT54G is a hacker's dream (runs Linux, naturally), and the
SVEASOFT developers have really gone to town. If you do take this
route and get stuck, the SVEASOFT forums are a decent resource.

Does this version support WPA? When I first tried this (back maybe 6
months or so ago), it didn't. There was talk on the forum of "sometime
but we're not sure when...". I moved on that that point...
