A connection timeout occurred. I have been receiving this error when trying to connect to the open wifi connection at my university. My wifi works perfect when I am using it on my home network. I have tried all the suggestions in forums online no luck.

Are you putting in the correct password?

Back up all data.

Launch the Keychain Access application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.

Enter the name of your wireless network in the search box. You should have one or more "AirPort network password" items with that name. Make a note of the name and password, then delete all the items. Quit Keychain Access. Turn Wi-Fi off and then back on. Reconnect to the network.

You can try Linc Davis' suggestion, as well as deleting the network and then reconnecting again.

From the menu bar, select

 ▹ System Preferences ▹ Network ▹ Advanced ▹ TCP/IP

What values are shown for the following?

• Configure IPv4
• IPv4 Address
• Subnet Mask
• Router

Try this...

Back up your personal data as a safety measure.

Go to to Library->Preferences->SystemConfiguration

Rename NetworkInterfaces.plist to NetworkInterfaces.plist.bak

Rename preferences.plist to preferences.plist.bak

Reboot the laptop.

In Finder menu up top pick Go/Go to Folder and type in /Library. From there on the paths are as I said above.

Why don't you ask the IT team at your school?

Oh yeah, Swank, that method doesn't work right. You must open terminal, and type in "open library". THEN open prefrences and so on and so forth.

From the menu bar, select

 ▹ System Preferences... ▹ Network

Click the Assist me button and select Assistant. Follow the prompts. You may get a warning that Wi-Fi is not available, that you're too far from the base station, or that you're using the wrong password.

Assuming that you've ruled out those possibilities, click the lock icon in the lower left corner of the preference pane and authenticate, if necessary. From the Location menu at the top of the window, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.

I just did it and it opens the root Library. I don't know why you can't.

System Preferences / Network.

Create a new location by clicking on Location: Edit locations. Then let the Mac take you through the rest of the steps.
