pairing quantum wifi with a series mfd

[rlariviere]

Just bought a new a75 NAG and a Quantum Radar a few weeks ago.
I am unable to pair the Quantum radar with my a75 MFD.
The WIFI option is turned on and I used that feature to download the new MFD SW version 17.45 using my home wireless router.
The radar is powered on, I opened the casing to see if there were any led's and yes, the main board has 2 green led's on plus one more flashing.
The WIFI card is also powered and I could see some leds lit.
My laptop has been able momentarily to see that the radar was on as I saw the SSID appear in the WIFi AP list.
the SSID is "Quantum_0160558"

Using the "Setup - System settings - External devices - Quantum radar - Pair with Quantum radar", I entered the SSID, as above plus the password" bd4d5348" as indicated on the labels provided.

Click "Connect" and then after 3-4 minutes I get the following message: "Could not find Quantum_0160558".

I need that system up and running by the end of this month,
Help please
