Does the NHD1W require any configuration out of the box?
No; the NHD1W is a plug-and-play device. Plug the device into an electrical outlet and,
once the WLAN and WWAN indicator lights stop flashing, you can use the device. For Wi-Fi
connectivity, the SSID (Service Set Identifier) and network key (password) are displayed on
the AirCard mobile hotspot’s LCD screen. If you would like to customize your settings you
can enter http://swi.hub into your Web browser to access the NHD1W’s homepage.
The NHD1W was connected but cannot get back online. What should I
do?
You may need to enable the periodic ping timer using the System Monitor feature (see page
50). This ensures that, if the connection drops (that is, outage on the network), that the
NHD1W will reboot after a number of failed pings and then force a re-connect. A timer
setting of around 15 minutes should be sufficient.
Note: The traffic generated by the periodic ping feature is counted as chargeable usage; please keep
this in mind when selecting how often to ping.
What should I do if the NHD1W is rebooting frequently?
Check the Services > System Monitor settings (see page 50) on the NHD1W homepage
and see if the “Force Reset every” timeout is set to a value other than 0. A value of 1, for
example means the unit will reboot every minute regardless of what happens. Reset it to 0 if
you don’t want this feature, or set it to a larger value if you don’t want the NHD1W to reboot
so often.
Can I change the name and password of my wireless network?
Yes, but the NHD1W uses the wireless network credentials from your AirCard mobile
hotspot. You can modify these settings by logging in to your AirCard mobile hotspot’s
homepage.
If you are operating in Power User mode, you can change your NHD1W settings from the
NHD1W’s homepage (http://swi.hub) and switching to advanced view. You can change the
SSID (Service Set Identifier), the security standard (WPA, WPA2, WEP) and your Wi-Fi
password.
