OK, I guess I was wrong! I thought I was connected to my external router but turns out I wasn’t paying attention and it was the internal connection I was connected to. I’ve since really messed things up. Forget about the external router for now. I have somehow wiped out any sign of the internal router!!!
I have tried resetting the DL (Holding reset for 5 secs, 30secs and hard reboot too) the three methods mentioned in the manual to no avail. When I power up the DL I can’t see the internal router in my WiFi settings anymore, the power led is solid and the WiFi is slow flashing indicating mixer is ready and waiting for connection, very frustrated now.
