Can I possibly change the trash wifi chip to something 5GHz?

Has anyone ever done it before? I might have the expertise. But I think those chips change too much, might be hard to find a chip that has exactly same pins right? Has anyone here ever succesfully done it before? Something like P-2812, you already open it to install openwrt, might aswell change the wi-fi chip, no?

What hardware are you talking about?
Are there no USB-Ports?

An expert in this subject matter would realize that:

  • All these WiFi radios need RF calibration data
  • RF calibration is unique to each board, even if they all use the same WiFi chip
  • The wireless certification for the device would be completely invalid
  • The firmware needs to be rebuilt with the correct device tree and drivers
  • The firmware needs to be rebuilt on every OpenWrt update

Realistically, you can't replace the WiFi chip. You might as well get another wireless router with better specifications. Even if you have USB ports, nobody makes a USB wireless adapter that works well as a general-purpose access point.[1]


  1. They can be useful for peer-to-peer or "travel router" scenarios. But they're all optimized for WiFi client usage. ↩︎

USB bus speed is rather slow, I tried many and they don't work well.
