Hi @rodders1947,
is the error about low bandwith? if not, could you please provide a screenshot?
if it is, The low bandwidth notification will only be triggered if it fails to receive specific response packets/ping from the spacedesk viewer app (and vice versa), probably due to network congestion on either side.
Additionally, Wi-Fi connections can be sensitive to various factors, such as distance or the number of connected devices, which can affect their performance.
You might want to explore using Wi-Fi Direct to see if your connection with spacedesk improves. Please refer to the ‘Performance Tuning -> Use Wi-Fi Direct / Wi-Fi Hotspot / Wi-Fi Access Point’ chapter in the user manual –
