The Linksys WPC54GS wireless notebook adapter is a small compact little unit, which simply plugs into the vacant slot on your notebook or laptop. This slot is usually activated by a small button, which will open the protective slot cover enabling engagement of the adapter. The unit is about 5 inches long and 2.5 inches wide with a height of about one quarter of an inch at it's highest.
One end of the unit has an enclosed connector which mates with its counterpart on the laptop/notebook. The other end has two small lights, which will light when the unit is a) Powered up and b) In Operation as a wireless adapter. None of this should be of consequence however until you have installed the appropriate software, which is supplied on CD, it is NOT advisable to attempt using the WRC54GS until this has been successfully accomplished. It is simply a matter of following a few on screen instructions to install the software and drivers and then you are in business.
The unit conforms with all current wireless protocol and transmits at a frequency of 2.4GHz, it gives a maximum speed of 54KBs and although it does claim to have a speed booster this is in all probability going to be obsolete unless you router has similar properties. If your routers top speed is 54Kbs as it most probably is then that's the fastest it's going to go.
After installing the software and plugging in the unit connection to your wireless router should be instantaneous or thereabouts. The software will give you a selection of wireless networks which are available you simply have to select the option which pertains to your specific router. Once done your laptop/notebook will be connected to the net.
I have found the unit to be very efficient and have never as yet lost connection with my router, however I feel that the software supplied to interact with your adapter seems somewhat antiquated. It just doesn't feel modern and seems kind of haphazard. The drivers seem to work fine since as I have indicated connection is never a problem. In most cases my connection is made before the laptop have finished booting up.
The unit currently retails at around £25-£30 which is quite reasonable I feel and if you want to connect your laptop to the internet it could easily cost you a lot more. Connection is steady and reliable the small lights indicate all is working and it is easily removed so that it can be stored safely until required. The reason I mentioned this is because the black part at the end of the basically silver unit is perhaps just over an inch long and this portion of the unit remains visible when connected to the laptop. It sticks out in other words and if left in such a position whilst being conveyed somewhere might possibly acquire a bit of knocking which I don't believe would damage it seriously but it might interfere with internal connections, so removal after use is probably a safe precaution.
