Are there any obstacles between the access
point and the connected device?
Check for any obstacles between the access point, the mobile
device, the computer, and the projector, and change their posi-
tions to improve communication.
Is the distance between the access point and
the connected device too far?
Make sure that the access point, the mobile device, the comput-
er, and the projector are not too far apart. Move them closer to-
gether and try to connect again.
Are there any Bluetooth devices or micro-
wave oven in the vicinity?
If the wireless connection is slow or your projected image con-
tains noise, check for interference from other equipment, such
as a Bluetooth device or microwave. Move the interfering device
farther away or expand your wireless bandwidth.
Are too many devices connected?
Reduce the number of connected devices if the connection
speed declines.
