Re: Can I do this?

Some thoughts:

- Would it be best to swap the two routers and use the WRT54G as your
client adapter on the distant end ? This could work - with
replacement firmware, depending on the version you have.

- Or, though your cable won't reach the shack, could you get a cable
and AP close enough to it to be within wireless range?
You would need a wireless adapter for your shack's pc, but that's
easy. There are good ones for as little as $40.

-Powerline networking, as Jeff mentioned is worth considering.

- Also, the usual advice is to try simple reflectors on the APs (and/
or client) to increase range. They can help a lot.
