Sierra aircard 875u connect to Playstation 3

Actually, screw sending me the message. It would probably help more people if I just posted it in the forums.
I have a Verizon Wireless Mobile Broadband card plugged into my laptop because no one in my house has a desktop and we never bothered around with WiFi. I assume this aircard you speak of is similar to mine.
First, connect to the internet with your card. For me there's an application I have to run where I basically just open the app and click Connect. If you have XP (which I really hope you do because I haven't tried this on any other OS) open your Network Connections menu. This can either be done by opening the "Start" menu, highlighting "Connect to" and clicking "Show all connections", or by opening the Control Panel from the Start menu and selecting "Network Connections".
In the Network Connections menu, find your current connection. It'll be the one that says "Connected" in gray letters under the title. I don't know if they all are, but for some reason mine was under the Dial-Up category on the list. Next, on the same menu, look for the "LAN or High-Speed Internet" category. You should have a setting there called "Local Area Connection". I have two. You want the one that doesn't say anything about WWAN or Wireless. It should say something about your ethernet card if you leave the mouse cursor hovering over it.
Now that you've identified both settings, right click the first one you found (the one that says "Connected") and click "Properties". Once that menu opens, click the "Advanced" tab. Check the box under "Internet Connection Sharing" that says "Allow other network users to connect through this computer's internet connection." In the "Home Network Connection" box, type the name of the second connection you found in the previous step (the one that uses your ethernet card). On some computers, instead of allowing you to type anything, that box will drop down and show a list of all your connections. Either way, you know which to pick. Click "OK", and fire up your PS3.
Now, at this point I plugged one end of an ethernet cord in my PS3 and the other into my laptop. Your computer might say something to let you know it has established a Local Area Connection. Log in to any Playstation Network registered profile on your PS3 and open Network Settings under the Settings tab. Go to "Internet Connections Settings". I was able to click "Easy" and my PS3 did all the work from there.
