PL-4 wireless / myGHL connections

[Tone]

I have a pre-loved PL4 with the most recent firmware and GCC F/W 7.28.

I have viewed the relevant videos numerous times in attempts to set up wireless connection and myGHL.

I did establish the wireless connection to my router (Netgear Orbi) and the LED on the face of the PL4 lit up solid green. GCC will not connect wireless.

I did establish a myGHL connection.

Then, the wifi LED turned off, the connection to the router disconnected and the GHL on the box top flashes red and the text 'MYGHL' flashes on the blue screen. myGHL will not connect.

In the GCC, all details have been wiped from the Communications tab - myGHL ID has reverted to 0, WiFi-Modus has reverted to 'Disabled', and the extensions to 802.11 are greyed out.

I can change the WiFi-Modus back to 'Client & Access Point'.

Nothing else can be changed.

What is going on here ? Has the wifi card pooped or is it a problem with GCC ?
