Performance tips

  • Use a USB 3.0 port for dual-band AC adapters to avoid bandwidth limiting on USB 2.0.
  • Place adapter away from metal obstructions and other USB 3.0 sources (USB 3.0 can generate radio interference around 2.4 GHz).
  • For better reception, use a short USB extension cable to position the adapter higher.
  • Match router channel and band for least interference (5 GHz has less congestion but shorter range).
