It depends where you are. If you are in a place with public wi-fi. You will need to learn the name of it. Then go to the light grey pie slice on the top right of your screen (to the left of the speaker icon) and scroll down. Make sure that Airport is turned off and scroll down to that wi-fi name and select it. If it has no password the grey pie icon should turn black. If it has a password, then you will need to put it in to make the wifi work. Again if you are in someone's house or school with wi-fi the same applies, you need to learn their name of it, go to that pie slice at the top (which will be light grey) scroll down. When you select the correct name the light grey pie icon will turn black. That means you have the internet connected!! In your own home or apt. unless your internet provider (cable or dsl) gives you a router, you probably will need a router (I use an airport extreme or express (router) with my mac) to be wireless. Then you will need to use the MAC airport utility to set that up. If you do not have it you will need to download it.
You may need to open it up again and remove first the airport card and turn it back on and if that boot your computer there's a possibility that your airport is causing the problem and the airport may be loose and touching some other parts on it.
1) You need to configure your Mac (the one connected to your modem) to share its Internet connectivity with other wireless devices. To do this, select System Preferences from the Apple menu, and then click on Sharing. 2) In the Sharing window, click on the Internet tab to bring up Internet Sharing. Select Built-in Ethernet from the Share your connection menu. Then, select Airport in the To computers using list 3) Click on the Airport Option button to configure some wireless security options. You Only want to be sharing your wireless connection with Your Other computer. Enter a Network Name, select channel as Automatic, and enable encryption and enter a WEP password, which will be required to join your new wireless network. now click on Ok 4) Now your mac is acting a wireless router just connect to your network from other computers and enter the WEP key when it ask for it. You found this to be an excellent solution when you don’t have a wireless router, but would like occasional wireless access in your home or small office. Regards Sandeep Shrivastava

Try turning off Airport. Your computer may be finding a wireless network and automatically switching to it, and getting an intermittent signal. Just a guess, but for a good ethernet connection you want to disable the Airport searching feature anyway. Open the System Preferences application, select "Network" and right on the top left of the resulting window there's a pretty big button that will either say "Turn Airport On" or "Turn Airport Off" - just turn it off if it's not already ...
Hope this helps!

When the power gets low, it will do silly things like turn off wireless to save battery. Prolly you just have to turn it back on. Click the airport symbol in the upper right hand area of your screen. Looks like a triangle made out of curved lines. A menu will drop down and one of the options will be "Turn Airport on". Click that.
You should be able to connect wirelessly from your Mac to your Cradlepoint router to obtain this information whether or not the phone is actually connected.
With your router powered up and operational, click the Airport icon on your top menu bar and turn your Airport on. Then click it again and watch for your Cradlepoint's wireless network name to appear. Using whatever WEP or WPA password you previously established, connect to the Cradlepoint.
Now under the Apple menu, choose System Preferences / Network. Select Airport, Advanced, then TCP/IP. (In releases other than Leopard, these choices may differ.) Look at the line marked "Router." That is the address you have to browse to in order to communicate with your Cradlepoint.
Depending on what model clamshell you have will determine a few things. One thing to take into considertion is does it have an airport card in it already? I know it does not have USB 2.0 so a dingle is going to be super slow.
The original apple airport cards that went into most of the computers before like 94 or so are the same and will work in your machine too.
Getting to it is a little more of a chore. go to iFixit.com for a detailed directions to install it and they also have items like this for sale. Check on eBay for a known good working pull apple airport card delivered for not more than $75.
The OS mac osx has the drivers installed on it to support this device so does OS9
First of all... Unplug the modem, unplug the Airport (WiFi router) and turn off the Airport connectivity in your MacBook.
After 5 full minutes... Plug in the modem.
Wait 2 full minutes... Plug in the Airport.
Wait 1 full minute... Turn on the Airport connectivity in your MacBook.
After all of that...
If you're still not back up and running and you're using an Apple Airport, open the Applications folder, open Utilities, open Airport Utility.
If you're using any other type of WiFi router, use the Network Diagnostics button that should show up in the web browser window when you try to go to any website.
