Quick question for my Dynon brethren. i have had a wifi adapter sitting around for awhile and finally got around to installing yesterday. I have a 10" and 7" display. When I tried to perform the set-up, I receive a message: OFFLINE: NO ADAPTER OTHER SCREEN. It isn't really that clear in the manual, but can I verify I will be required to have two wifi adapters (one on each screen) for wifi to be functional?
