Nintendo Switch

[Colossus]

I CRACKED THE CODE! Okay, I didn't crack any code, nor found the solution to the left Joy-con. HOWEVER I did do some testing. I brought the system with me to work today and tested both Joy-cons in the warehouse. I was able to get 100 feet with no problem with both Joy-Cons and no antenna mod.
I brought it home and hooked it up to my TV. Let me grab my tape measure....
22 feet and complete disconnection.
Let's take it out of the dock. 30 feet away, a wall in between me and the switch un-docked... slight connection issues.

The dock is one of the problems!
Now why would I be able to still connect to my Switch at work 100 feet away? Large room, only electronics are the lights really, small wi-fi signal.
At home, there's a lot to create issues with signals.  When I was testing at work, I did keep the Joy-Con BEHIND my back the whole time I tested to create interference. I even had my coworkers stand in front of the switch to block the signal as well.  
At home, the Joy-Con was in front of me.
This blob of solder is the antenna. You can solder a wire to it and bend it to the bottom to fix this issue, however I DO NOT RECOMMEND THIS to anyone who doesn't know how to solder and work with electronics.
The ribbon cable that you need to remove is a pain in the ass to put back in (damaging this cable can put you back quite a bit of cash) and the battery plug will come apart if you don't know what you are doing. 


This is the video to fix the antenna issue.
