If you are unable to see the ScreenBeam in your connection menu it may be your wireless card. By default, ScreenBeams use a 5GHz channel for wireless display, so you must have a dual-band wireless card. You can check the model of your wireless card in Device Manager on your PC, look in the Network Adapters section. If you don’t have a dual-band wireless card check out these workarounds.

Once you’ve ruled out VPN and Group Policy, make sure you have the latest drivers for your Graphics and Network cards. Out of date drivers can stop a connection or cause intermittent connection issues. You can check your driver versions by going to Device Manager and expanding Network Adaptors section, copy the name of your wireless card and Google the name of your card and look for driver updates from your PC OEM or the hardware OEM. The process is the same for your Graphics card. Windows Update does not always have the latest drivers, which is why we recommend this process.
Firewall settings may also need to be adjusted antivirus software is a consideration also

If your Windows Desktop Freezes or Locks Up When I Try to Connect to ScreenBeam
There is an issue that may occur on Windows systems where components of the desktop may freeze or lockup when connecting to ScreenBeam. This behavior typically occurs when a user reconnects to ScreenBeam, either by the side or top overlay panels, immediately after a failed connection. This results in the overlay panels being frozen on the screen and various desktop components, such as the system tray, becoming unresponsive. The PC will typically need to be rebooted to recover from this state. Click here for information and link to the Hotfix.
When deploying your ScreenBeams you must take several variables into account.
When deploying your ScreenBeams you must take several variables into account. Our recommended best practice is to stagger P2P channels on receivers that are adjacent to each other, as well as avoiding the channels that your infrastructure APs are on, this reduces the possibility for interference. Depending on the size of your room and density of wireless devices you will want to adjust the transmit power, it is recommended to use medium or high.
