Wi-Fi Device Through the Ethernet Connection

Are there any wi-fi devices that connect to the computer through the RJ45
connection?

Yep, Must wireless routers have a few switch ports.
If that is what you are looking for.

Yep. There are wireless routers, wireless access points, and wireless
ethernet bridges. Also wireless print servers, wireless RS-232
adapters, and wireless printers. Each has their own place in the
galactic scheme of things. All can connect to a computah via an RJ-45
connector. If you would kindly disclose what you are trying to
accomplish, it might be possible to suggest which of these would be
appropriate.

Okay, what I have is a laptop computer and I don't have the PCMCIA card
option, so I am just wondering if something like a wireless ethernet bridge
would allow me to get access to a wi-fi network when staying at a hotel,
etc.

Absolutely. Methinks a "travel router" might be suitable. It is
especially useful if you want to connect more than one device, such as
a VoIP device. For example:

<http://www.3com.com/products/en_US/detail.jsp?tab=features&pathtype=purchase&sku=3CRT RV10075>

If these are overkill, then a simple wireless ethernet bridge will do.
There's a list of possible candidates at:
<http://wireless.wikia.com/wiki/Wi-Fi#Wireless_Ethernet_Bridges>

The main problem is that unlike a wireless client that has all the
connection information configured inside your laptop, both the
wireless routers and wireless bridges need to be configured inside the
router or bridge. Therefore, connecting is a 2 step process. First
you select the SSID of the hot spot using a web browser pointing to
your wireless router or bridge. It then issues your computer an IP
address via DHCP. You can then connect to the hot spot and
authenticate using the web browser. It's an additional step that
sometimes causes some confusion, but that's the price of having an
external ethernet connected wireless device. Note that some "travel
routers" have a utility to make make this easier by storing commonly
used connections on the laptop instead of inside the travel router.

Also, you might want to look around your unspecified model laptop and
see if there is a USB connector available. If so, a USB wireless
adapter is probably cheaper and easier to deal with.

Thank you very much. I think that this might be exactly what I am looking
for. And I see some pretty nice reviews on the unit.

As Jeff pointed out, the USB solution is very easy to implement.
Personally I like the cigarette pack sized Linksys WUSB54G adapter as
it had a flip up antenna that was closer to a true onmi antenna than
the "loop antenna" that I've seen inside the USB dongles that act more
like a dipole (disclaimer: others may have different experiences).
Alas its been discontinued.

On the other hand, a "travel router" with an external antenna jack
would be nice. I haven't used them, but I'm going to say it plays well
with other access points as opposed to a Linksys WAP54G in client mode
that only connects to other Linksys access points and wireless router.
Also (and correct me if I'm wrong), a travel router might be USB
powered where a stand alone device may need a wall-wart for power.

On a side note, the Hawking USB dongle can act like an access point
(other brands might also work in that mode, Kind of like an ad-hoc set
up, but better as you don't have to have everyone reconfig their
wireless connection for ad-hoc under properties which may be beyond
the skill set of brain dead cooperate managers). I really don't know
as I hardly ever play with non-commercial grade home and small office
gear. Ummm...unless Linksys as I'm a certified partner.

If you don't need the extra features in a travel router, then the
simplest solution would be a USB adapter. There are a few out there
that take external antennas. You can just go with the internal if
reception is good, or put the external antenna on to improve
reception. Very compact.

Hawking makes one like this too. They also make one with a fixed
directional antenna for even better range. A bit bulkier.

Thank you for all of the replies so far. I have been out of town for a few
days so I haven't had a chance to get back to this until now.
Unfortunately, neither PCMCIA nor USB is an option in this particular case.
I did get a chance to try a Belkin Wireless G Gaming Adapter and that did
work, so now I am trying to narrow my focus on if I should buy a:

-Wireless Travel Router

-Wireless Gaming Adapter

-Wireless Ethernet Bridge

I suspect that I can probably eliminate a wireless ethernet bridge because I
think that the wireless travel router and wireless gaming adapters will be
more compact for travel. (Is that correct?) I am trying to get the best
value for my money, of course. I suppose having the ability to connect an
external antenna could be helpful, too, on occasion. The Belkin Wireless G
Gaming Adapter that I tried seemed pretty good, but I just want to make sure
that I don't buy it and then find out a week later that a different brand is
better for whatever reason, be it price, range, ease of set up, etc.

This site has some helpful information, too. Can anyone suggest any good
web sites so I can learn more about wifi? It looks like there are a number
of sites out there, but I am just wondering what some of the best sites are.

I have a 2 wireless bridges the wet11 and a wet54G that are only 5x4x2
inches. The game adapter by the same company WGA54G is 5x5x2 inches.
Their WGA11B is 5x3x1 inches.

I like how that site considers the Newegg user ratings as well as
magazine reviews. Magazine reviews miss a lot about real-world use.
Consumersearch figured out that the Buffalo router is very popular
even though none of the experts really reviewed it.

Here's the usual link for wireless info:
