3.
Determine the COM port number that your Sierra Wireless device (that is, your Overdrive Pro 3G/
4G Mobile Hotspot) is using.
In the following example for Windows, the Device Manager shows that COM 18 is used. In your
case, the COM port number might be different.
(If you don't know how to access the Device Manager, see
.)
4.
Configure your GPS application to use the same COM port. For help, see the documentation of
the GPS application.
How Do I Access My Corporate Network Through a VPN?
Once you complete a wireless connection, you may need to launch an extranet client provided by
your company and supply the appropriate user name and password to gain access. For support,
contact your company help desk.
Are Terminal Sessions Supported?
Terminal sessions (for example, via
telnet
or
ssh
) are not supported.

Extending Battery Life
When you’re not using the device, turn it off, or end the 3G/4G connection. (Click
Disconnect
on
the home page or in the Mini Window.)
Connect the device through the micro-USB cable to your computer, and disable Wi-Fi. (See
“Disabling Wi-Fi When Connected Through USB” on page 90.)
Adjust the LCD — do one or more of the following:
±
Turn the LCD off (
Advanced Settings > Device > Display > LCD Backlight
).
±
Decrease the brightness of the LCD (
Advanced Settings > Device > Display > Backlight
Settings > On Battery/USB Power
).
±
Set the LCD to turn off sooner. (See “Setting the LCD Timeout” on page 67.)
Configure the setting (for when battery powered or connected via USB) to “Short Wi-Fi Range”
(
Advanced Settings > Wi-Fi > Network > Battery or USB Powered
).
Enable standby (low power) mode. (See “Standby (Low Power) Mode” on page 45.)
Turn off the lighting of the power button
(that is, LED) (
Advanced Settings > Device >
Display > Power Button LED
).
Limit the number of Wi-Fi users (
Advanced Settings > Wi-Fi > Network > Max Number of Users
).
If you have 3G but not 4G coverage, set
WAN mode
to “3G only” (
Advanced Settings > WAN >
Setup > WAN Mode
).
Set
Wi-Fi > Network > Wi-Fi Power Save Mode
to “On.”
(If your computer tends to lose the Wi-Fi connection and stops responding, set this field to
“Off.”)
If GPS is enabled and you’re using your device from the same location, set
GPS Mode
to
“One-time.” (See “Setting the GPS Mode” on page 93.)

Device Location
Avoid moisture or extreme temperatures.
For improved reception, place the device near a closed window.
Place your device within easy reach of a reliable power supply and the computer to which it will be
connected.
Improving Signal Strength
Make sure you’re inside a 3G or 4G coverage area.
Try reorienting your device.
Move the device and your computer to another location — you may be in or near a structure that is
blocking the signal. Every obstacle (for example, walls, ceilings, furniture) between the Overdrive
Pro 3G/4G Mobile Hotspot and other wireless devices decreases the signal strength.
Place the device in a centralized location, as high as possible in the room.
Make sure there’s plenty of space around your device to provide the best signal reception.
Keep the device at least 3–6 feet away from electrical devices that generate RF interference (for
example, microwaves, TVs, 2.4 GHz cordless phones, cellular phones, baby monitors, wireless
speakers). If you’re not using these electrical devices, turn them off.
If possible, place your devices so that the signal passes through open doorways or drywall, as
opposed to concrete, brick, metal, walls with insulation, and so on.
If you cannot obtain service, contact your service provider — a network or account problem may be
preventing you from obtaining service.
Improving Wi-Fi Performance
Try a different channel number. (See “Wi-Fi Channel” on page 89.)
Check whether any device updates are available. (See “Updates” on page 57.)
See the tips in “Improving Signal Strength” on page 120.
Limit the number of Wi-Fi users (
Advanced Settings > Wi-Fi > Network > Max Number of Users
).
Select a longer Wi-Fi range (
Advanced Settings > Wi-Fi > Network > Long Wi-Fi Range > Battery or
USB Powered
or
AC Powered
).

3.
Double-click the Wi-Fi client network adapter of your computer — for example, “Intel(R) WiFi
Link 5100 AGN” in the screenshot below.
4.
If the Wi-Fi client network adapter is by Intel, click
Advanced
and, in the
Property
list, click
Power Management
and move the slider all the way to the right (to
Highest
). Click
OK
.
— or —
If the Wi-Fi client network adapter is not by Intel, select a configuration with minimal power
savings (to maximize throughput).
Security Tips
Change the Wi-Fi network name (SSID) and Wi-Fi password on a regular basis. (See “SSID
(Wi-Fi Network Name)” on page 83 and “Wi-Fi Password” on page 86.)
Disable SSID Broadcast. (See “Network Panel” on page 79.)
Use the highest level of Wi-Fi security that your devices support. (See “Wi-Fi Security” on
page 85.)
Change the login password. (See “Changing the Administrator Password” on page 71.)
Use MAC filtering to specify computers that are or aren’t allowed to connect to the network.
(See “MAC Filter Panel” on page 81.)
Note:
The above settings are often controlled by 3
rd
-party value-add applications and may be automatically
changed. If Wi-Fi performance improves for a while after performing the above steps, but then
declines, recheck the above settings.

Finding the MAC Address
You’ll need to know the MAC address of a device when:
Assigning an IP address based on a MAC address (when using DHCP). (See “DHCP Static IP
Assignment List” on page 100.)
Allowing or denying computers access to the network. (See “Allowing or Denying Computers
Access to the Network” on page 87.)
The steps to finding the MAC address of a device vary, depending on your operating system.
Windows
1.
Open a command prompt window.
±
Click
Start

Type
cmd
or
command
, and click
OK

At the command prompt, type
ipconfig/all
and press
Enter
.
3.
Write down the Physical Address for the entry that relates to the wireless network connection; it
appears as a series of numbers and letters — this is the MAC address of your wireless adapter.
Mac OS X

), select
System Preferences
.
2.
Select
Network
.
3.
Select the adapter that is connecting to the routing hardware.
