This problem is also appearing on my CQ18.
I’ve done quite a bit of trouble shooting. This also happens when your Mixer is connected with a Lan Cable.
This could be due to a “Dry Solder” on the main board (network connection/port).
Usually when this happens, and you leave the Mixer on for about 5-10 minutes and you restart it, then the Network will initialize.
Mine is definitely getting worse though.
I did ask our local distributor about an exchange. I don’t feel comfortable with the idea of having my 2 month old CQ opened up and repaired. It’s going to feel second hand.
