According to an M100 review on youtube the camera would not connect to an Apple Airport if it is set to the "802.11a/n - 802.11b/g/n (Automatic)" mode. It would connect only if the airpot is configured to a slower compatibility mode.
What is your experiance with the Airport ? I plan to buy an M100, but only if it is compatible with Airport full speed mode.
The below FAQ may help you:
Which Wi-Fi networks are compatible with the monitor?
The monitor is compatible with 802.11 b/ g/ n networks (2.4GHz).
It is not compatible with 802.11a (5GHz) network.
I guess this confirms the M100 is not compatible with Apple standard Airport mode. They use 2.4 and 5 GHz combined to achieve a higher throughput.
I tried several times to connect my B120 with QR code and different setups of 802.11 a/n-802.11 b/g/n without success as several others have experienced.
First when i configured my Time Capsule router without a password i succeded to connect and configure my B120 monitor.
Afterwards i reconfigured to security WPA2 personal and disconnected from my In.sight account - then i connected my Ipad with new networksettings to the network and reconnected to In.sight account and then connected my B120 again with a QRcode. ( you must first reset your B120)
For what it's worth I'm using my B120 with a Time Capsule without any issues. The thing you have to keep in mind is that the monitor does not have a 5ghz radio so you have to configure your Airport/Time Capsule to create a dual network environment (5ghz & 2.4ghz) and set up the monitor to use the 2.4ghz network.
