Check
Miracast
channel
Surface Hub
If you run a network scan, you should see Surface Hub Miracast
listed as an access point. If Surface Hub's Miracast network appears,
but you can't see it as an available device, try to adjust the Miracast
channel.
When Surface Hub is connected to a Wi-Fi network, it uses the
same channel settings as the Wi-Fi access point for its Miracast
access point. For troubleshooting purposes, disconnect Surface
Hub from any Wi-Fi networks (but keep Wi-Fi enabled), so you can
control the channel used for Miracast. You can manually select the
Miracast channel in Settings. You'll need to restart Surface Hub
after each change. Use channels that don't show heavy utilization
from the network scan.
Check
drivers
External
device
Ensure the device drivers on your external device are up to date
and the latest firmware is installed for your wireless display or
adapter. In
Device Manager
, select
Network Adapters
, open the
Wi-Fi adapter and video adapter and check for an updated driver
version.
Check
firewall
External
device
The Windows firewall can block Miracast traffic. The most
straightforward test is to disable the firewall and test projection. If
Miracast works with the firewall disabled, add an exception for:
- C:\Windows\System32\WUDFHost.exe
- Allow In/Out connections for TCP and UDP, Ports: All.
