Does the performance improve after turning Airplane mode on and then off?

OR

Does the performance improve after turning Wi-Fi off and then on for your computer?

Consult your device’s documentation about Airplane mode.

There may be too many devices connected to the network. Enable load balancing, if it hasn’t been done already.

Additionally, consult your network equipment manufacturer about how to geographically reduce the amount of visible devices. For example, Cisco refers to this as Location Specific Services (LSS).

Turning Airplane mode on and off can help resolve screen sharing issues. If stability issues with Screen Share occur again, use this troubleshooting wizard.

Is your device unable to connect to the display to share a video?

OR

Is the video dropping frames or stuttering?

OR

Is the screen’s resolution you are sharing is higher than 1920 × 1080?

The resolution of the shared device’s screen might exceed (or “be larger than”) 1920 × 1080. Refer to the manufacturer’s instructions for your device to learn how to change the resolution.

Does the issue occur with different devices from different manufacturers?

There may be an issue with the device’s wireless capabilities, the device’s drivers need to be updated, or another workaround. Work with your equipment manufacturer to find a resolution

You can connect your devices to the display, but the device is having performance issues. How many SMART Board interactive displays are affected?

Contact SMART Technical Support. You’ll need the display’s serial number.

For more information about the display’s serial number, see SMART Board 2000 and 2000 Pro.

Does the issue improve when you change the network frequency (from 2.4 Ghz to 5 Ghz or vice versa) and/or channel?

There might have been too many devices connected to the network causing congestion on the network, or other bandwidth-related problems.

If you only changed the network frequency, consider changing the channel.

You may want to consider limiting the number of devices on the same subnet. Contact your device manufacturer for more information.
