I am just thinking out loud here. I wonder how many people feel it is essential to upgrade both wifi cards, just the controller's wifi card or none at all. I guess you could say it is my thought (or question) of the day!!
Just replacing the controller's card would be ineffective. Communication is two way. It's not accomplishing anything if the controller reach the solo but the solo can't reach the controller. In fact, the controller already has higher gain antennas than the solo, so it's already more powerful than the solo to begin with. Do both or don't waste your time.
That said, my question to you would be "WHY". Don't go replacing WiFi cards just because you see other people doing it. This is a mission need modification. If you are not regularly flying far enough way to be losing connection, there is absolutely no reason to do the WiFi card swap, or change antennas, or do any other modifications of the sort. So to answer your question "is it essential", the answer is NO.
I installed both upgrade wifi cards, as I live and fly around a heavily treed area. I wanted the extra punch.
Sadly, it won't. The nature of higher frequencies is that they do not bend and bounce around obstructions. It will still lose connection.I suppose one reason could be if I were to get close to a canopy of trees or to orbit a tall structure where I would lose line of sight momentarily, maybe the "extra" punch would keep from losing connectivity.
