After initial reviews of the Nintendo Switch noted widespread issues with the left Joy-Con occasionally losing its wireless connection to the console, hackers have found that opening up the controller and adding a simple piece of wire seems to increase its effective range greatly. Now, Nintendo is offering a similar fix to users who call in to its support line, and the company may be selling redesigned, fixed controllers at stores right now.

Over at CNET, writer Sean Hollister recounts his experience with Nintendo customer service, which he calls “just about the best electronics customer service I’ve ever experienced.” After getting a free overnight shipping label for his controller after a weekend call, Hollister received his controller back in the mail just five days after sending it.

Opening up the fixed controller showed that Nintendo didn’t have to do much to correct the connection issue. The only apparent difference is a small piece of black foam sitting on top of the corner of the controller board that houses the Bluetooth antenna trace.
