Mavericks upgrade wifi problem exclamation mark
Upgraded to Mavericks last night. Since then, no internet connection. iMac connects to the right AP but shows an exclamation point.
Wifi was working before the install and the other Macs with previous versions of OS X are connecting fine with the same AP.
Anyone had a similar problem? Any ideas what could be wrong?
Thanks!
iMac (27-inch Mid 2011)
