|3||Can I edit the Teacher or Student username?||The username login dialog and list are not editable. This is by design to avoid inappropriate word entry.|
|4||The thumbnail for the student PC does not appear in the Teacher App, even though the student is connected to the ScreenBeam receiver.||
Make sure the Student PC has the Classroom Commander Student app running and connected to the same ScreenBeam receiver as the Teacher PC.
|5||The Student PC becomes disconnected and no longer appears on the Teacher Classroom Commander console. This may happen during a lengthy session.||
This could be due to the Wi-Fi noise in the environment. Reconnect Student PC to the same ScreenBeam receiver as the Teacher PC.
|6||When the teacher disconnects from the ScreenBeam receiver via Teacher Classroom Commander app console, all the Student PCs get disconnected from the ScreenBeam receiver.||This is by design. The teacher can terminate the class session and force all the Student PCs to disconnect by properly disconnecting from the Classroom Commander Teacher app console.|

When the Teacher or Student PC is connected to the ScreenBeam receiver, Windows 10’s audio is automatically switched to output via the Projector/TV speakers. User can manually select Windows audio to output on the desired playback device.
|11||Microsoft Surface device with wireless driver version v15.68.9125.57 fails to maintain connection with ScreenBeam 960 receiver.||
Roll back to known good Marvell Avastar AC wireless driver version 15.68.9120.47.
The driver can be obtained from the Microsoft Windows Update catalog site for manual installation if the rollback option does not work.
|12||Windows 10 system with Qualcomm Atheros wireless adapter (e.g. QCA61x4A) cannot connect to ScreenBeam receiver if the system WiFi is connected to a WPA2-Enterprise AP with 802.11r.||
Update Qualcomm Atheros wireless adapter's driver version 18.104.22.1680.
If the driver version 22.214.171.1240 is not available, you can obtain it from the Microsoft Windows Update catalog site.
