Go to a computer accessories shop and look for the green USB to PS2 Mouse adapter. Or you can buy it online. See the picture at this link (check that the port matches your PC mouse port): http://www.rudyp.com/usbtops2moad.html IMPROVED: Please note the answer above is for converting a USB to PS2 connector, NOT USB to Serial Port. A USB to Serial Port adapter does not, to my knowledge, exist. So please verify if you want a PS/2 (small, round connector) or Serial Port (long, flat connection with many pins) Also, the color of the adapter may vary.
Buy a new one.

A network card is required in order for a computer to communicate with a network. The adapter usb serial port is needed to connect a wired computer to an Ethernet. The Ethernet connects the computer and the Internet modem. Wireless network adapters are more popular because they can be set up almost anywhere in the home. The wireless network adapter is equipped with a LED light that shows the user whether it is working or not. Most laptops contain a wireless network card that is built in. You can buy network boosters to increase the signal. Older laptops may contain a wireless card that doesn't support the newer protocols. It is difficult to replace an older wireless card inside a laptop computer.
Try heading over to Best Buy, if they don't have it, the next big bet would be searching for it on NewEgg, and lastly if they don't have that special adapter, try going to Radio Shack. They have random stuff there.
There are many places to purchase a USB wireless adapter. It depends if you want to purchase one online or in store. Best buy has many options to choose from, both online and in store.
