MAX-OTG-U4-SF with poor wifi signal with external antenna

I ve been trying to test the external antenna, but always I have less than a half range compare with the internal. Any solution or specific config?

Best Regards.


  1. Have you enable external Wi-Fi Antenna (AP > Settings > Wi-Fi Antenna = External)?

  2. You test with 2.4Ghz or 5Ghz?

  3. Any USB modem connected to MOTG during your testing?
