iMac suddenly stopped seeing my WiFi network, which works with every other device in the house My iMac suddenly stopped recognizing my WiFi network. Numerous other devices are connected to the same network (2 MacBooks, iPhone and LG Nexus). The network doesn't display in available networks list, but I can see all other WiFi networks available from neighbours. I have tried following things already:


Restart iMac
Restart WiFi router
Add new 'location' in network settings
Change radio channels in my router
Manually input network SSID, security type and password (it keeps telling me that network with this name doesn't exist)


The iMac sits very close to the router and other devices work flawlessly in the same place. What's worth mentioning is that this behaviour was sudden, that is everything as working fine until it suddenly stopped.

I'd appreciate any help!
I had the same problem, suddenly. Solution? I opened the list of saved networks and removed it, it appeared in the list of networks in range immediately.
