    5. This shows the real-time signal level for the access point. Walk the premise toward increasing signal levels to locate the AP and turn it off. You can turn on/off the audio beeps that get faster as you get closer to the AP by selecting the sound icon in the lower left hand corner of the screen.

  • Over Utilized Channel

    Over Utilized Channel

    1. Are there too many devices communicating on a channel causing intermittent problems? Over utilized channel from clients or access points can be the problem. No body likes to be crowded, here is how AirCheck G2 can help you isolate this problem.

    5. This shows details for the selected channel including utilization, number of APs & Clients on the channel. If 802.11 utilization is > 25%, and APs >2, you have a problem and should look at the details of your access points by selecting “APs”.

    6. This shows the APs operating on the channel. Possible mitigations:
      1. Re-assign channels on some APs.
      2. Locate unauthorized APs and remove it
