Notice
Safety and
Hazards
Due to the nature of wireless communications, transmission and reception of data can
never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally
lost. Although significant delays or losses of data are rare when wireless devices such as
the NETGEAR® modem are used in a normal manner with a well-constructed network,
the NETGEAR modem should not be used in situations where failure to transmit or
receive data could result in damage of any kind to the user or any other party, including
but not limited to personal injury, death, or loss of property. NETGEAR accepts no
responsibility for damages of any kind resulting from delays or errors in data
transmitted or received using the NETGEAR modem, or for failure of the NETGEAR
modem to transmit or receive such data.
Do not operate the NETGEAR modem in areas where blasting is in progress, where
explosive atmospheres may be present, near medical equipment, near life support
equipment, or any equipment which may be susceptible to any form of radio
interference. In such areas, the NETGEAR modem MUST BE POWERED OFF. The
NETGEAR modem can transmit signals that could interfere with this equipment.
Do not operate the NETGEAR modem in any aircraft, whether the aircraft is on the
ground or in flight. In aircraft, the NETGEAR modem MUST BE POWERED OFF.. When
operating, the NETGEAR modem can transmit signals that could interfere with various
onboard systems.
The driver or operator of any vehicle should not operate the NETGEAR modem while in
control of a vehicle. Doing so will detract from the driver or operator's control and
operation of that vehicle. In some states and provinces, operating such communications
devices while in control of a vehicle is an offence.

represent a commitment on the part of NETGEAR. NETGEAR AND ITS AFFILIATES

INCLUDING, BUT NOT LIMITED TO, LOSS OF PROFITS OR REVENUE OR ANTICIPATED
PROFITS OR REVENUE ARISING OUT OF THE USE OR INABILITY TO USE ANY NETGEAR
PRODUCT, EVEN IF NETGEAR AND/OR ITS AFFILIATES HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES OR THEY ARE FORESEEABLE OR FOR CLAIMS BY ANY
THIRD PARTY.
Notwithstanding the foregoing, in no event shall NETGEAR and/or its affiliates
aggregate liability arising under or in connection with the NETGEAR product, regardless
of the number of events, occurrences, or claims giving rise to liability, be in excess of

2. You may wish to provide a separate Wi-Fi network connection for temporary ‘guest’ users.
3. By default, the Secondary network uses 5 GHz and broadcasts the same network name as the
Main network (using 2.4 GHz). A Dual-Band device (smartphone, tablet, etc.) will connect to the
strongest of the two signals.
4. By default, the Secondary network and Main network both use 2.4 GHz. The Secondary network
name is the same as the Main network name, with “-GUEST” appended.
Advanced users may choose to customize the following options in the AT&T Unite Pro
Manager:
Note: If you choose a predefined profile and then change detailed options in the AT&T Unite Pro
Manager, the profile automatically becomes a custom profile.
• Frequency — Use 2.4 GHz for longer range (but slower) Wi-Fi, or 5 GHz for higher
throughput and less interference (but shorter range).
(Note: If you change the Frequency, the Mode field automatically sets to the best
value.)
• Enable secondary Wi-Fi network — Select this to use dual band Wi-Fi (2.4 GHz and
5 GHz) or to give temporary access to guest users.
• Guest Wi-Fi — Select this to use the secondary Wi-Fi network for temporary
visitors without letting them see the devices using your Main Wi-Fi. Give your
guests the Guest Wi-Fi network name and password, which are different from
Main Wi-Fi.
• Wi-Fi network name and password — Keep the randomly assigned names and
passwords, or change them as appropriate. For example, you may have a standard
method for referring to Wi-Fi networks, or for assigning passwords.
