It can do that. The problem is to get the right routing, which
I can't figure out how to accomplish with the standard Linksys
firmware for a WRT54G.
Adding routing that will allow connection to other parts of the
LAN is easy. Go to the route table entry form and add a route
to, for example, 192.168.0.0 with a netmask of 255.255.0.0, and
bingo every 192.168.x.x address will be correctly routed between
the wireless and wired LAN. That is useful if, for example, the
wired LAN is all on one subnet, say 192.168.0.x and the wireless
net is all assigned to a different subnet, such as 192.168.1.x.
However, I've not figured out how to add a default route to the
ethernet LAN ports on a WRT54G, as opposed to the WAN/Internet
port.
Instead, I've used both the Satori and HyperWRT firmware
upgrades, and they both do that with ease (enable telnet, telnet
in and add the command). With Satori that can be made to
survive a reboot by using the web menu to save the startup.
With Hyperwrt fireware one puts those statements into the
startup file, then saves it.
But without a default route with your firewall as the gateway,
no Internet access is possible.

Personally, I'd use a wired net for that. I'd bet that teenager
wouldn't have nearly the hesitation at pulling CAT5 that you do!
(Yeah, scary... but that is *nothing* compared to what he does
when you aren't looking! Let him do the hands on part of
installing the whole thing, right down to the jacks. He'll
probably take a lot of pride later on in pure ownership

Unless you specifically add a route, nothing the wireless side can
access anything with a 192.168.0.x address.
What does the WRT54G's route table look like?
