1. NOTE ABOUT THIS USER GUIDE
While this user guide applies to a specific Arris modem/router deployed by WOW! for Internet service,
this guide may also be used for other Arris Modem/Routers that WOW! deploys for service. Minor screen
layout and configuration options may dier from model to model. However, most configuration tabs and
screens will be similar and have the same look and feel.

7072.U.1601.O 5
2. ACCESS AND LOGIN TO MODEM
Enter the default IP Address of the modem into your browser URL field and press <Enter>.
• Default IP Address: 192.168.0.1 The following screen should appear.
Enter the default User Name and Password and click <Apply>.
• Default User Name: “Admin”
• Default Password: “Password” (When the EMTA is reset)
• For increased security, at the time if installation, WOW technicians will change the default password to
a unique 12 character password and provide to the owner.
• If the EMTA is factory reset, the password will default to “password” and could allow access to the
EMTA by unauthorized users. If this occurs, please refer to the unique 12 character password provided
at the time of installation and reset the password to this 12 character string.

7072.U.1601.O 6
3. BASIC SETUP
3.1 System Basic Setup
The following four (4) selection are available to customers via the <Basic Setup> Tab. Clicking on the
question mark icon next to each option will give the user additional information about that specific
configuration.

7072.U.1601.O 7
3.1.1 Basic Setup
Use this option to select the appropriate language.
3.1.2 Wireless 2.4 GHz
This radio frequency applies to many older and existing WIFI connectivity options. Most WIFI devices
operate using this option.
3.1.3 Wireless 5 GHz
This radio frequency applies to many newer WIFI connectivity devices. 802.11ac uses this frequency.
3.1.4 2.4G/5G WPS Settings
WIFI Protected Setup (WPS). Select this option to enable WPS.
3.2 Login Settings
Login Settings are available to customers via the <Basic Setup> Tab. Clicking on the question mark icon
next to each option will give the user additional information about that specific configuration.
Wireless SSIDs & Pre-Shared Keys should be kept as the factory defaults unless a customer desires to
change them.
The SSIDs and Pre-Shared Key are provided by the manufacture on the bottom of the Modem along with
the CMAC address and other information.

7072.U.1601.O 8
The Login Settings page is where the user can change the default password. At the time of installation, a
WOW! technician will set the default password to the CMAC of the modem.

7072.U.1601.O 9
4. WAN SETUP
4.1 Dynamic
4.1.1 DHCP
Dynamic Host Control Protocol (DHCP) is enabled by default. Additionally, the IP Address, Subnet Mask
and Gateway Address fields are auto-configured at initial turn-up with WOW! provided Internet service.
Unchecking DHCP is an advanced routing feature that disables internal routing and allows users to use
their own router.
The first or topmost Ethernet port should be used in this
configuration when connecting to a customer provided router.

7072.U.1601.O 10
4.2 Static
No changes are needed on this configuration page for normal operation. Static IP assignments are an
advanced routing feature that should only be configured and utilized as needed when ordered accordingly
from WOW!.
This is not common.

7072.U.1601.O 11
4.3 Dynamic (IPv6)
No changes are needed on this configuration page for normal operation.

7072.U.1601.O 12
4.4 Static (IPv6)
No changes are needed on this configuration page for normal operation. Leave this box un-checked. As
with the STATIC configuration page, STATIC (IPV6) assignments are an advanced routing feature that
should only be configured and utilized as needed when ordered accordingly from WOW! This is not
common.

7072.U.1601.O 13
5. LAN SETUP
LAN Settings are advanced configuration options that do not need to be altered for normal operation.
5.1 LAN Settings
5.1.1 LAN IP Settings
192.168.0.1 is the default IP address assigned to the modem and does not need to changed for normal
operation. The Subnet Mask value does not need to be changed either. These two default settings,
combined, allow for 253 devices to be connected, physically or via WIFI, to the modem. One (1) of these
254 IP addresses is actually the modem itself. The IP address assigned to the modem can be thought of as
the gateway IP address.

7072.U.1601.O 14
5.1.2 DHCP Server Settings
Leaving this option enabled (radio button checked) allows for the modem to assign IP addresses
dynamically to devices within the IP address range specified. The default range is from 192.168.0.2 to
192.168.0.254 (253 potential devices). Lease time and domain names are additional advanced configuration
options. These do not need to be changed for normal operation.
Note: Should static IPs be assigned on the LAN, they should not be within the dynamic IP range. If they
are, undesirable and unpredictable network behavior may occur.
5.1.3 DNS Override
Alternate DNS servers may be entered and utilized. This is an advanced routing feature and should not be
changed for normal operation. Leaving this option un-checked is the WOW! default configuration.
5.1.4 DNS Relay
This is an advanced routing feature and should not be changed for normal operation. Leaving this option
un-checked is the WOW! default configuration.
5.1.5 NAT
<RoutedWithNAT> is the default configuration option and should not be changed for normal operation.
5.1.6 UPnP
Enabling UPnP is the default configuration for normal operation.

7072.U.1601.O 15
5.2 LAN Settings (IPV6)
All IPV6 LAN settings are set to the following default entries at service activation. No IPV6 addresses need
to be configured. DHCP Server, DNS Override or DNS Relay options do not need to be selected. These all
should be left unchecked (disabled) for normal operation with WOW! Internet services.

7072.U.1601.O 16
5.3 Client List
The Client List page lists actively connected devices to your network. As an advanced feature, individual
devices may be manually entered. This is used in conjunction with the advanced static address routing
features of the modem. By default and for normal operation, adding devices, or clients, along with static IP
addresses is not required.

7072.U.1601.O 17
5.4 Ports
All Ethernet ports are configured to a default state to be enabled, set to Auto, set to Full-Duplex and set to
a speed of 1000. Modification of these settings may adversely aect network operation.

7072.U.1601.O 18
6. WIRELESS 2.4 GHZ
6.1 Basic
6.1.1 Enable Wireless
This option needs to be checked to in order to utilize the WIFI functionality of the modem.
6.1.2 Wireless Network Name (SSID)
The provided SSID, or WIFI network name, is the default WIFI network users will connect to. One SSID is
assigned to the 2.4 GHz radio while another is assigned to the 5Ghz radio. Both may be manually changed
at the user’s discretion to a description that is more fitting to their environment.

7072.U.1601.O 19
6.1.3 Broadcast Network Name (SSID)
Leave this box checked (enabled) in order to visually identify your WIFI network.
6.1.4 TX Power Level
TX (Transmit) Power Level pertains to the WIFI strength. Leaving the setting on high will ensure the
maximum range in which devices will be able to connect to your modem via WIFI.
6.1.5 Channel
Leaving this option set to <Auto> will improve WIFI connectivity and performance by minimizing
interference with other radio and WIFI signals.
6.1.6 AP Isolation
Leave this option unchecked (Disabled).
6.1.7 WMM
WMM is an advanced modem setting used to improve throughput performance for certain real-time
applications like VoIP (Voice over IP/Internet) or interactive video.
6.1.8 Security Mode
WOW! Recommends WPA2-PSK (AES) as the most robust WIFI security option. Note: TKIP is the most
compatible, however, TKIP is slower than AES and will limit wireless speeds.
6.1.9 Pre-Shared Key (PSK)
This is the default password for WIFI. Upon service activation, this will be the CMAC of the modem.

7072.U.1601.O 20
6.2 Advanced
6.2.1 Wireless Network and 802.11n Specific Settings
The following screen shot shows the default settings that should be used for normal operation. These do
not need to be change for optimal performance.
