@snoack The cadillac solution would be to get two Peplink AP One Minis, put one in the front of the RV and one in the rear, and set them to fixed 2.4GHz and 5GHz channels that don’t overlap (which you may need to alter when you get to a new RV park if it’s crowded).
Another trick: If you don’t care about FAST internet, but more about RELIABLE, then you can use the “secret” channel 165 as discussed here:
In short, it’s a 5GHz channel that can only be 20MHz wide, which means it’s often unused.
