Are any firewall-containing applications installed?
If any applications which contain firewalls are installed, the installation may hang up at the [Projector search in progress]
display (some firewalls function even when not started).
If this occurs, firewall settings must be changed in order to allow connection to the wireless network. See the User’s Manuals
for all applications containing firewalls to perform these settings.
