if your talking about setting up a wireless network in your home then its really not that hard. It will take some time but its not hard at all. But remember to password encode your network so no one outside of your house can use your network.
connection goes from (cable or DSL modem) to wireless router. Typically, you use the setup CD to "instruct" the wireless nic to pic up the router's signal. easy peasy~
And WEP is a piece of shit, you can still hijack and decode packets out of the air with very little effort. The easiest and most effective way to secure a wireless network is to isolate your network via MAC Address- which means that only the PC's that have been added to the "safe list" will be able to access it.
That's a little advanced; so do a little research before you set that up.
MAC filters aren't entirely safe either, as faking a MAC address is easier than breaking WEP (assuming you know the MAC you need to fake). WPA encryption (look on the box of the router for it) is a far better option.
Your all talking as if wireless routers are easy to connect! Ever tried Belkin? Peice of crap.
First i've got to change my USB connection to an Ether connection by reinstalling my modem (which is a bitch) and if i can't get another wire to fit in the back then i have to get a new tower! And from then on it'll be fun and games all over again!
