Hi..  Looking for some help. 

I have three S4's and one X50.  The S4's are =     US/3.6   /    1.4.1    /   20230324

The Router or main deco is in my basement, I then have one with ethernet connected to the 1st floor, then a satillite on the 2nd floor, and another satellite on the roof which is the X50.

I have moved the 2nd floor one into my camper in the driveway which is in site of the roof top X50 (although much higher as its on my roof so the camper in reality is about 5 stories down).  Im shocked and surprised that the 2nd foor is connection to the first floor Deco which is the furtherest away from where I now have the 2nd floor Deco. 

I see the X50 has a "connection preference" option that my S4's do not have so I cannot force the 2nd floor to the outdoor rooftop X50, which would make sense it would connect to. 

Is there a way to make a "connection preference" with the S4?  or do I have to buy a more expensive X50 to do this and put that inside my camper or just outside it?????

Any help would be greatly appreaciated.  Thanks Kevin
