I was told to change the channel of my AP in case of connection issues. Can I pick any channel (from 1 to 11) from the
list?
If your school has a wireless network, please work with your IT team to ensure that the channels used by your TI-
Nspire™ Navigator™ system co-exist well with that network.
Even though the AP supports all channels from 1 to 11 at 2.4 GHz, it is recommended that you configure the AP to
only
use channels 1, 6 or 11
. Due to the way the channels are assigned, using other channels may result in reduced
performance.
If you are using the newest TI-Nspire™ CX Navigator™ access point and the TI-Nspire™ CX Wireless Network Adapters v2
you have the option to change the frequency band from the 5GHz band (default) to 2.4 GHz. The operating channels for
the 5GHz frequency are 36 (default), 40 44, 48, 52, 149, 153, 157, 161, 165.
Note: The default frequency band on the new TI-Nspire™ CX Navigator™ access point is 5GHz. The CX Wireless
Network Adapters v2 are the only TI-Nspire™ wireless clients that can connect to the AP when it is operating on
the 5GHz band.
Some of my TI-Nspire™ handhelds disconnected after not being used for some time. What’s going on?
The TI-Nspire™ handhelds disconnect from the wireless network after 60 minutes of inactivity. This is done to preserve
the rechargeable battery in the handheld. You will need to press the ‘
ON
’ button on the TI-Nspire™ handheld to re-
connect the TI-Nspire™ handheld to the network.
My AP gets disconnected during normal use. What can I do to avoid this?
Please change the power settings on your computer to disable ‘hibernate’ during normal use. If you need help with
updating your PC configuration, please contact your IT department.
What other things do I need to know about the new TI-Nspire™ CX Navigator™ access point?
The new TI-Nspire™ CX Navigator™ access point has a few differences from the earlier models of TI-Nspire™ access
points.
•
The new AP does not have a separate power adapter – it uses the USB connection for power. This means that it
starts the ‘boot’ process after it is plugged into the PC and won’t be available for use for about 30 seconds after
the USB cable is connected.
•
Since the AP does not connect to a separate power source, it is important for the AP to be connected directly to
your computer. It should
NOT
be connected to the handheld via an external hub.
•
The internal antenna in the new AP has the same range as the other AP. However, during classroom use please
ensure that that AP is not behind a monitor or other electronic equipment. Whenever possible, try to maintain a
clear line of sight between the AP and the handhelds.
