My early-2008 iMac will connect to my wireless router only if I turn off WPA2 protection. With WPA2-PSK on, the iMac seems to connect, but generates the "No Internet connection" error with the exclamation point over the wifi icon in the status bar. In other words, it connects to the router, but cannot get an IP address. It works perfectly fine if I turn off WPA.
iMac, OS X Yosemite (10.10.1), early 2008
Hi hlco,
I'm sorry to hear you are having issues with your wireless connection. If it appears that you are able to connect to your network but get a "No Internet Connection" error, and you are running Yosemite on your iMac, you may want to try running Wireless Diagnostics to see what it returns, as outlined below:

Have you tried turning the router off for a couple on minutes and then back on? Also restart the computer.
