I have not put in a sim card yet and have been operating using the alpha WiFi antenna. I had my maiden flight today including doing a waypoint mission wiht QGC.

I had a lot of disconnect / reconnect announces. I was not flying far - 50m max and no more than 10m high.
I have a travel router taped to the top of my monitor as the connection point.

What can I look at to see if the signal is fluxuating and really that weak?
Do I need to shift to 5G? (maybe the SANAV anntennas will make a difference?)

I am also starting to learn how to use logs. If there is a good tutorial I can look at I will certainly spend time there.
