individually.
5. Network ID (SSID): Network ID is used for identifying a Wireless LAN. Client stations
can roam freely over this device and other Access Points that have the same Network ID.
The factory default SSID is “DG-WM2015DIO”, you can change it to a meaningful
identifier for the wireless users to easily find out.
6. SSID Broadcast: By default, the SSID Broadcast setting is “Enable”, and the device will
broadcast beacons that have some information, including SSID, to the air, so that wireless
clients can know how many AP devices by scanning the network. Therefore, if this
setting is configured as “Disable”, you can hide the wireless network from being scanned
DG-WM2015DIO User Manual
31
by wireless clients. Those who know the SSID can manually specify the SSID on their
client device to connect the hidden wireless network.
7. VLAN ID: This device supports mapping of a SSID to a certain VLAN ID to separate
work groups across wireless and wired domains. By default, it is not enabled. If you
enable this function, you have to specify a VLAN ID for the wireless network.
8. Max Supported Stations: You can specify the number of maximum stations that can
associate to the SSID simultaneously.
9. Channel: The radio channel number. The permissible channels depend on the Regulatory
Domain. The factory default setting is auto channel selection. It‟s recommended to
choose a channel that is not used in your environment to reduce radio interference.
10. Wireless Mode: The RF module supports 802.11b/g/n modes. You can also choose “N
only”, “G/N mixed” or “B/G/N mixed”. The factory default setting is “B/G/N mixed”.
11. Bandwidth: The default setting for Bandwidth is “Auto”. You can change it to “20MHz”
with care if some clients are suffering from the connectivity problem in higher bandwidth
setting.
12. Authentication & Encryption: You may select one of the following authentications to
secure your wireless network: Open (include 802.1x), Shared, Auto, WPA-PSK, WPA,
WPA2-PSK, WPA2, WPA-PSK/WPA2-PSK, or WPA /WPA2.
Open
Open system authentication simply consists of two communications. The first is an
authentication request by the client that contains the station ID (typically the MAC
address). This is followed by an authentication response from the AP containing a
success or failure message. An example of when a failure may occur is if the client's
MAC address is explicitly excluded in the AP‟s configuration.
In this mode you can also enable the 802.1x feature if you have another RADIUS
server for user authentication. You need to input IP address, port and shared key of
RADIUS server here.
In this mode, you can only choose “None” or “WEP” in the encryption field.
Shared
Shared key authentication relies on the fact that both stations taking part in the
DG-WM2015DIO User Manual
32
authentication process have the same "shared" key or pass phrase. The shared key is
manually set on both the client station and the AP. Three types of shared key
authentication are available today for home or small office WLAN environments.
Auto
The gateway will select appropriate authentication method (Open or Shared)
according to the Wi-Fi client‟s request automatically.
WPA-PSK
Select Encryption mode and enter the Pre-share Key. You can fill in 64 hexadecimal
(0, 1, 2…8, 9, A, B…F) digits, or 8 to 63 ASCII characters as the pre-shared key.

specify the IP address and port number for the RADIUS Server, and then fill in 64
hexadecimal (0, 1, 2…8, 9, A, B…F) digits, or 8 to 63 ASCII characters as the shared
key. The key value is shared by the RADIUS server and this router. This key value
must be consistent with the key value in the RADIUS server. The available encryption
modes are “TKIP”, “AES”, or “TKIP/AES”.
WPA2-PSK

whose authors commit to using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public
Licenses are designed to make sure that you have the freedom to distribute copies of free software
(and charge for this service if you wish), that you receive source code or can get it if you want it,
that you can change the software or use pieces of it in new free programs; and that you know you
can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or
to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if
you distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must give
the recipients all the rights that you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software and (2) offer you this license
which gives you legal permission to copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain that everyone understands
that there is no warranty for this free software. If the software is modified by someone else and
passed on, we want its recipients to know that what they have is not the original, so that any
problems introduced by others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the
danger that redistributors of a free program will individually obtain patent licenses, in effect
DG-WM2015DIO User Manual
62
making the program proprietary. To prevent this, we have made it clear that any patent must be
licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a notice placed by the
copyright holder saying it may be distributed under the terms of this General Public License. The
"Program", below, refers to any such program or work, and a "work based on the Program" means
either the Program or any derivative work under copyright law: that is to say, a work containing
the Program or a portion of it, either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in the term "modification".) Each
licensee is addressed as "you".
Activities other than copying, distribution and modification are not covered by this License; they
are outside its scope. The act of running the Program is not restricted, and the output from the
Program is covered only if its contents constitute a work based on the Program (independent of
having been made by running the Program). Whether that is true depends on what the Program
does.
1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in
any medium, provided that you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to
this License and to the absence of any warranty; and give any other recipients of the Program a
copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer
warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus forming a work
based on the Program, and copy and distribute such modifications or work under the terms of
Section 1 above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed the files
and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is
derived from the Program or any part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must cause it,
when started running for such interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a notice that there is no warranty
(or else, saying that you provide a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this License. (Exception: if the
Program itself is interactive but does not normally print such an announcement, your work
DG-WM2015DIO User Manual
63
based on the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are
not derived from the Program, and can be reasonably considered independent and separate works
in themselves, then this License, and its terms, do not apply to those sections when you distribute
them as separate works. But when you distribute the same sections as part of a whole which is a
work based on the Program, the distribution of the whole must be on the terms of this License,
whose permissions for other licensees extend to the entire whole, and thus to each and every part
regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written
entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with the Program (or
with a work based on the Program) on a volume of a storage or distribution medium does not
bring the other work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Section 2) in object
code or executable form under the terms of Sections 1 and 2 above provided that you also do one
of the following:
a) Accompany it with the complete corresponding machine-readable source code, which must be
distributed under the terms of Sections 1 and 2 above on a medium customarily used for
software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any third party, for a
charge no more than your cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be distributed under the terms of
Sections 1 and 2 above on a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute corresponding
source code. (This alternative is allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such an offer, in accord with
Subsection b above.)
The source code for a work means the preferred form of the work for making modifications to it.
For an executable work, complete source code means all the source code for all modules it
contains, plus any associated interface definition files, plus the scripts used to control compilation
and installation of the executable. However, as a special exception, the source code distributed
need not include anything that is normally distributed (in either source or binary form) with the
major components (compiler, kernel, and so on) of the operating system on which the executable
runs, unless that component itself accompanies the executable.
If distribution of executable or object code is made by offering access to copy from a designated
place, then offering equivalent access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not compelled to copy the source
along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided
DG-WM2015DIO User Manual
64
under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program
is void, and will automatically terminate your rights under this License. However, parties who
have received copies, or rights, from you under this License will not have their licenses terminated
so long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not signed it. However, nothing
else grants you permission to modify or distribute the Program or its derivative works. These
actions are prohibited by law if you do not accept this License. Therefore, by modifying or
distributing the Program (or any work based on the Program), you indicate your acceptance of this
License to do so, and all its terms and conditions for copying, distributing or modifying the
Program or works based on it.
6. Each time you redistribute the Program (or any work based on the Program), the recipient
automatically receives a license from the original licensor to copy, distribute or modify the
Program subject to these terms and conditions. You may not impose any further restrictions on
the recipients exercise of the rights granted herein. You are not responsible for enforcing
compliance by third parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement or for any other
reason (not limited to patent issues), conditions are imposed on you (whether by court order,
agreement or otherwise) that contradict the conditions of this License, they do not excuse you
from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then as a consequence you may
not distribute the Program at all. For example, if a patent license would not permit royalty-free
redistribution of the Program by all those who receive copies directly or indirectly through you,
then the only way you could satisfy both it and this License would be to refrain entirely from
distribution of the Program.
If any portion of this section is held invalid or unenforceable under any particular circumstance,
the balance of the section is intended to apply and the section as a whole is intended to apply in
other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right
claims or to contest validity of any such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is implemented by public license practices.
Many people have made generous contributions to the wide range of software distributed through
that system in reliance on consistent application of that system; it is up to the author/donor to
decide if he or she is willing to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest
of this License.
8. If the distribution and/or use of the Program is restricted in certain countries either by patents or
by copyrighted interfaces, the original copyright holder who places the Program under this
License may add an explicit geographical distribution limitation excluding those countries, so that
distribution is permitted only in or among countries not thus excluded. In such case, this License
DG-WM2015DIO User Manual
65
incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the General Public
License from time to time. Such new versions will be similar in spirit to the present version, but
may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies a version
number of this License which applies to it and "any later version", you have the option of
following the terms and conditions either of that version or of any later version published by the
Free Software Foundation. If the Program does not specify a version number of this License,
you may choose any version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs whose distribution
conditions are different, write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free Software Foundation; we
sometimes make exceptions for this. Our decision will be guided by the two goals of preserving
the free status of all derivatives of our free software and of promoting the sharing and reuse of
software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS
AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF
ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE
TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
