Solution
When the wireless projector is idle, its ID is
shown at the bottom left corner of the projection
screen. For a WEP-enabled projector, the Session
Key will also be shown.
Make sure that the current user has
Administrator's privileges, and that Lenovo
WDLP Driver item in My Computer → Property→
Hardware→ Device Management is enabled. Then
re-install the program.
Confirm that the WLAN adapter is in the laptop
and its drivers are installed. Make sure that
WLAN adapter item in My Computer →
Property→ Hardware→ Device Management
Wireless adapter is enabled.
Make sure that the antenna of the laptop's WLAN
adapter is turned on and try again. Remove and
then re-insert the WLAN adapter, repair or
disable it, then re-enable. Select Information→
Wireless Setting→ Wireless Repair in the OSD
menu. Try to refresh again after the ID of the
projector appears on the bottom left corner of the
projection screen.
Firewall software can interfere with the
performance of the wireless projector. Try
disabling any firewall software. Make sure that
there is no network routing software which may
change the network configuration and try again.
Repair the WLAN adapter by re-inserting, or
enable/disable it and try again.
Strong radio interference can interrupt the
operation of the projector. Typically it will recover
within 30-60 seconds.
Wireless projection uses a wireless adapter card
(WLAN) in your laptop computer. Therefore, you
cannot connect to the Internet unless you have a
second wireless adapter, or you have a wired
connection.
Due to the possibility of unreliable networks, the
projector takes some time to realize that the
WLAN adapter in the laptop has been disabled.
The projector will wait for about 30 seconds
before ending projection. You can quit the
wireless projection immediately by selecting the
Wireless button on the remote controller.
