Best location for wireless router near Model X?

I added a powerline wifi extender and signal is very strong in garage now.

As I recall, the WiFi antenna is in the dash for the S & X (the dash end pieces... One side has the cell antenna & the other is WiFi, right?), so reception isn't going to be great in the first place. That said, I haven't had any issues with WiFi signal in the garages since switching to a single Ubiquity UniFi AC Long Range access point in the center of the house--the whole 1/2 acre property is covered now.

 

Not sure what you mean by this. Are you saying in the car you only have 1 BAR for WiFi? If so, and the router is in the next room I would say you have a problem with the Router. My router is like in the next room as well and I get almost full strength.

I did not have a problem before (when using multiple Apple Airport Extremes) but I also just recently changed routers to use Google Wifi mainly because I wanted the statistics (per client) and a MESH Wifi.

 

I've always read here that the WiFi antenna was in the right side mirror. I have a repeater in the kitchen, one wall away from the car and on the right side of it. I get a full strength reading from the car.

 

Are you using 5GHz? 5GHz moves a lot of data but has less penetration through walls. If your router also does 2.4 Ghz switch to that and see if it helps.

 

MCU1 cars (X/S builds before about March 2018) only did 2.4GHz. MCU2 can do both 2.4GHz and 5GHz.

Also this thread might have some useful tidbits:
