Megamind,
I apologize if I get too simplistic as I don't know exactly what your skill set is, so if this is too basic, I apologize in advance. Without knowing the specifics of how your wireless network at home is set up I'm going to work under the assumption that it's set up like 85 or so percent of the market. You connect to the internet using some form of broadband connection (cable or dsl modem, etc). Connected to the modem is a device called a wireless router.
If you're like me, you may have a couple of PC's connected directly with a wire and any wireless devices connect over the air.
I guess the easiest way to step you through this is if you have a wireless laptop (that's running Windows). In theory you should have a little wireless network icon located somewhere next to the clock (called the systray). When you hover your mouse over it, it will tell you what wireless network you're connected to. The network name displayed there is generally called the SSID, as noted in my original post. Write that down and be sure you denote any capitalized letters, numbers, spaces or special characters (if you have any).
Just left click on that icon once, and it will display a little menu that not only tells you what wireless network you're connected to but if there are any others in the immediate area. Right click on the one you're connected to and when the little context menu and then left click on the word "properties".
This will bring up the security tab. If whomever set up your wireless network was smart, they set it up so it's encrypted. My guess is that it's WPA2-Personal or WPA2 PSK (Preshared Key). The ecryption type is probably aes or tkip, and then below that, you should see a little option called network security key. Below the key box you will have a little check box that says show characters. Write that down and also pay attention to what each character is (alpha, numerical or special character)
Now that you have all that info, go to the settings screen of your warp. At the very top, you will see "Wireless and Networks".
1) Ensure Wifi is turned on
2) Network Notification (self explainatory, but your call)
3) Under wifi networks, you should see your home network listed there. if it's not there or it says disconnected, click on "add Wifi network, directly below.
4) For the SSID, put in the name of your network.
5) For the security type, unless it actually is open, click the word open and then find the item that matches the security type that's listed on your laptop. (most probably WPA or WPA2-PSK), then tap it.
6) It will take you back to the add network tab, directly below the security cell you will probably see password. That's the password that was taken from the network security key on your laptop. Enter that in so it's identlcal to your laptop. When finished tap Done, down in the lower right hand corner.
7) Click Save.
Once finished with all that, just click the home button and after a few seconds you should see the icon (refer to your manual) for wireless, by your 3g or battery icon.
From that point on you should be able to access the web.
Be advised. While running wifi at home is great, because it's several orders of magnititude faster than cellular, it can also chew through a fully charged battery much faster than just the cellular radios.
Hope that helps and good luck.
peace.
