And my PC (Windows XP) is fairly old (about 6 years old) and I'm not even sure I would be able to connect to my wi-fi if I had the router. How can I check?
Since no one has addressed this particular question:
Whether your fairly old XP system will be able to connect wirelessly depends on one thing: a wireless network adapter. If it does not, you will have to use a wired connection OR purchase a wireless adapter. These can be either an internal wireless card or a USB wireless adapter. The trend now is toward the USB adapters.
There is one way to check to see if you have a wireless adapter on your system.
Start menu/Control Panel/Administrative Tools/Computer Management/Device Manager which is on the left side of the page.
Expand NETWORK DEVICES. Post what is listed under Network Devices.
As for the connections, it's really simple.
Line from your internet provider goes to the modem. An ethernet cable goes from the modem to the router port labled INTERNET, WAN or WLAN.
If you use a wired connection, another ethernet cable goes from a router LAN port to your computer.
Your router will have instructions for setting everything up. There should also be a cd included which will walk you through setting up your network and securing the network with a password.
It's not difficult to do. If I can do it anyone can. My advice, buy a router and go for it. Once you do it you will say GEE, that was easier than I thought it would be.
