Possible Cause 3: There are too many WIFI channels in your environment.

   Proposed Solution

  • Sometimes the MaxTester has trouble maintaining WIFI connection where there are a high number of active WIFI channels.
  • If possible move to an environment where there are fewer WIFI channels.
  • If possible use the wired ethernet port.
  • If possible work off-line and then connect to WiFI in a more suitable environment.

Possible Cause 5: You may have an older unit with a single WIFI antenna.
