You have a
conflict on the
operating
channel used by
your
TI-Navigator™
access point.
• A conflict could be caused if another access
point or a cordless telephone is using the
same channel.
• To try a different channel, open Network
Manager, click
Actions > Setup Wizard, click
Next, select your hardware type, and click
Next. On the Operating Channel Selection
screen, in the Operating Channel list, click a
different channel number, and click
Finish. If
the changing the channel doesn’t correct the
problem, try a different channel.
The computer’s
firewall is
blocking
communications.
• If you have a software firewall on the
computer, such as ZoneAlarm® or the built-in
firewall included in Windows® XP Service
Pack 2, the firewall may be blocking
communications between the computer and
the TI-Navigator™ network.
• Try disabling the firewall completely. If the
network begins working, the firewall is
probably causing the problem.
• Get help from your system administrator, or
contact Texas Instruments for help.
