I dropped my ps4 :( and now it keeps disconnecting my controllers after a few minutes of playing, sometimes right after another. They still can connect but not for long, I already looked at replacing the antenna but if it still can connect does it mean it’s fixable or is it something more internal?
The vast majority of the time the WiFi antenna is all that needs replacing. The guide is located here. It’s possible that the wifi board itself is bad or the solder joints underneath it but that is not likely. I hope this helps.
