"Airport card" is, I think, a misnomer. All iMacs (for the past few years) have wi-fi capability built-in.
First thing to try is to reset the SMC.
The, go to system preferences>network. At the top it should say "status: connected." Also, there is a button that refers to the wi-fi. Click on it if the wi-fi is off.
You do not indicate which OS X version you are running (this is based on OS X 10.8).
The Wi-fi button isn't there. it only shows that I'm connected via Ethernet. I am running 10.7.5 OS
It has never worked since I bought it in 2009 when it was running 10.6.
When I want to '+' wifi, it doesnt show up in the network list.. Only bluetooth and firewire and ethernet.
Any other suggestions? SCM won't change anything else to the computer?
Thanks a a lot.
Is there a way to see if the actual hardware with driver has been installed in the iMAC?
it shows that tht following software versioin are installed for Wifi;
CoreWLAN: 2.1.3 (213.1)
CoreWLANKit: 1.0.3 (103.2)
Menu Extra: 7.2 (720.1)
configd plug-in: 7.4.1 (741.1)
System Profiler: 7.0 (700.3)
IO80211 Family: 4.2 (420.3)
WiFi Diagnostics: 1.0.2 (102)
AirPort Utility: 6.1 (610.31)
But I can't find any hardware in the list of 'system report' that refers to 'airport card'
Is there a way to find out if there is any of such a device built in the iMac at all?
the hardware overview shows: no devices installed of the following:
- Fiber Channel
- Hardware RAI
- PCI Cards
- Parallel SCSI
- Thunderbolt drivers not loaded.
it's a iMac, OS 10.7.5, but started with 10.6 when I bought it, 4GB, ethernet, 27".Wifi never worked.
any other solutions that could work? thanks for your help so far Barry!
