Hi All

Solved the missing Airports - after installing OSX 10.10
after 2xs 5 hours of frustration I found it mentioned on a MacRumors page:
http://forums.macrumors.com/showthread.php?t=1740885&page=2

Quote:
Same problem as so many others. After new install of Yosemite on a MacBook Pro, 
I was able to connect to internet via wireless through TimeCapsule, but could 
not access TimeMachine; AirPort Utility showed internet, but no configured 
wi-fi devices.

After some mentions above of firewall settings, I turned off firewall in
System > Security&Privacy > Firewall. Turned Wi-Fi off and back on, 
and--voilà--the TimeCapsule was visible, and with a green dot.

I was able to turn the firewall back on after adding AirPort Utility to the 
list of FileSharing (AFP) apps. after that I continued to see TimeCapsule and 
was able to conduct a Time Machine backup as before the Yosemite installation.

Hope this helps.

Hi Brian

Check you have the cable plugged into the correct port on the Airport. (as they 
have two,…one WAN port and some Ethernet ports). It should be the one that 
looks like a circle.
Possibly also, the new Netgear may not do DNS relay (I'm sure that's not the 
right term,.but I have a headache, so bear with me).
As it's only a one port modem, it expects to hand one just one IP address. 
Normally a wireless one will do DHCP and hand out IP addresses to all connected 
devices, as it knows you're going to have more then one.
And you've probably got the Airport DHCP set to Bridge mode.
(under Airport Utility the Network. Router Mode set to Off (Bridge Mode).

What you'll need to do in the above is change this to something like DHCP Only 
or DHCP and NAT.

I would imagine,..and I'm guessing here without seeing it,…so again bear with 
me,…
The Netgear Router will be something like 192.168.0.1
When you plug in your computer your IP address will most likely be 192.168.0.2

If you can confirm that you're getting an IP address like that, and it's not 
changing (or that the Netgear doesn't do DHCP), then that will point you in the 
right direction as well. (as it only expects to hand out one number ever).
So if that is the case, then you can set the Airport to do DHCP Only. Set the 
DHCP range to something like 192.168.0.5 through to 192.168.0.200
Then click Update in the Airport Utility.

This then means you can still get to the Netgear on 192.168.0.1, and all other 
devices will be in the range from 192.168.0.5 onwards. 
So the modem is just doing the internet, and the Airport is handing out it's 
numbers to connected machines.

Hope that helps. (I've assumed a few details there without knowing exact models 
of things, or seeing the network),…but hopefully should get you started on the 
right track.

Kind regards
Daniel
