Details

1. Verify that the settings on the Mikrotik Groove or Ubiquiti Bullet are correct
   
   • Check the SSID
   • Check the PSK
   • Frequency should match the frequency of the wireless access point, or be set to 'Auto'
   • If the radio is a Mikrotik Groove, and AP is Ubiquiti, enable TKIP Unicast on the Mikrotik Groove
2. Verify that the 4RE DVR can communicate with the radio (Groove or Bullet)
   
   1. Select Menu
   2. Select Settings
   3. Select Diagnose
   4. Select Wireless
   5. Verify 'Access Connected' is 'Yes'
      1. If 'No' then the 4RE DVR is not communicating with the radio
