This isn't all that complicated. All you need to do is grab a wireless
router and patch it to your existing ethernet hub/switch via LAN ports.
Assuming you already have a DHCP server, gateway, etc., you disable these
features on the wireless router, since they are redundant. Patching may
require a crossover cable, or a standard cable will do if one of the units
has an uplink port, or supports MDI/MDIX.

You could also just buy a wireless access point, but they tend to be much
more expensive (min $80, often higher). But the basic AP features available
in a typical consumer model of router is usually more than adequate.
Purchasing a cheap wireless router vs. a dedicated access point could save
you considerable expense. Of course, you could just replace your existing
wired hub/switch/router with a wireless router (most have at least 3-4 LAN
ports). But if you want to continue using your existing huh/switch/router,
then patching a wireless router/AP to it is a simple solution, and will add
LAN ports in the process.

As far as quality of reception, the only way to know is try it. There's
always the possibility of local issues/interference. But in general, 50-75
ft. is not going to be an issue, you may simply not get the optimal
performance. And you can always choose one of the new MIMO wireless routers
which extends range quite a bit. I use an 802.11g router across two floors,
a staircase, a couple walls, about 50 ft., and reception is decent
(18-22mbps). I recommend a wireless router w/ detachable antenna so you can
optionally purchase a high-gain directional antenna, should reception prove
a problem. Some models, like those from Belkin, have a permanently attached
antenna, yuck.

But overall, this is pretty simply setup, much less complicated than you
might have expected.

The advice is good. Distance could be a problem and the newer preN routers
from Belkin and Linksys have a noticeable
greater range than the G router. I recommend going the N route. Adding the
new wireless router to your existing router would work as "Jim" suggests.
Place it as close to the window/wall facing the office as you can. As Jim
says, disable DHCP on the 2nd router and configure it as a router and not as
a gateway.
Costs a bit more, but should be worth it. You don't even need an N adapter
in the computer to pick up on the extended range. A G card will work OK.
However, I do recommend going with a router and adapter from the same
company. In theory any one should work, BUT, should you need help, Belkin
will blame Linksys and vice versa.
