I can't tell exactly what type of wireless card you have inside but
it's probably a MiniPCI card which means you're going to have some
difficulties attaching an external antenna. More on this later...
The device you're probably thinking of is an external laptop antenna.
Something like this:

The problem is that there's no easy way to attach the coax cable to
the MiniPCI card without drilling a hole in the laptop for the coax
cable. The MiniPCI wireless card also probably uses u-FL connectors,
which are not very rugged and will destroy themselves if improperly
handled. A good tug on the coax cable, and the connector is busted.
I've seen people drill a hole in the laptop case and mount an SMA
connector, and solder the coax to the board, but methinks that might
be a bit extereme for a relatively new laptop.
The right way to do this is to add an external PCMCIA or USB wireless
card that has external access to the RF connector and which will allow
easy access for the antenna coax. Something like this kit:

Note that this is 802.11b and not 802.11g. There are other cards and
kits that will do this. The basic idea is to get the coax cable out
of the laptop without destroying the laptop. The rest is antenna
design.
If this is too complex or expensive, you might wanna try a cheapo
802.11g USB dongle. The advantage is that you can extend the USB
cable 16ft away from the laptop. Since there's no RF on the cable,
there's no RF loss from the coax cable. The USB radio will give you
more options in terms of locating the the radio, such as out a window
or sitting on top of your head (I've seen it done). If you go
shopping for one of these, try to get one that has an obvious tilt up
antenna as the circuit board and sub-miniature antennas found in most
of the tiny USB radios absolutely suck for antenna gain.
>Signal I connect to is linksys.
Much depends on the model number of the Linksys, the type of antenna
used, and the number of walls and obstructions you have to go through
between you and the Linksys. If you have no control over this
wireless router, then you have to do all the improvements on your end.
However, if you can do something about its location or antenna, you
may be able to get away with nothing more than a bigger antenna or a
simple repositioning of the wireless router.
