Customer needs to upgrade. Support for AP model 207 wasn't added until 8.2.1 release. We are currently on 8.2.5 release. Customer should review the release notes for all releases prior to upgrading so that they are aware of the changes that have been made since 8.2.0. Customer should also be aware that the latest firmware may have features that were introduced that the past AirWave version did not have toggles for, so it's in their best interest to routinely update the AirWave server for optimal functionality paired with the latest device firmware releases.
