INTRODUCTION



1.4 IP Address Setup

Before you log into the HT-EMN2’s GUI, your computer’s IP address must be in the same subnet as the HT-EMN2. This allows your computer to communicate with the HT-EMN2.

NOTE: See IP Addresses and Subnets on page 26 for background information.

If your computer is configured to get an IP address automatically, or if you are not sure, try to log in to the HT-EMN2 (see GUI Overview on page 18).

If the login screen displays, your computer is already configured correctly.

If the login screen does not display, your computer is not configured correctly. Follow the procedure in Manual IP Address Setup on page 16 and set your computer to get an IP address automatically. Try to log in again. If you cannot log in, follow the manual IP address setup procedure again, and set a specific IP address as shown. Try to log in again.

NOTE: If you still cannot see the login screen, your HT-EMN2’s IP settings may have been changed from their defaults. If you do not know the HT-EMN2’s new address, you should return it to its factory defaults. See The Summary Screen on page 19. Bear in mind that ALL user-configured settings are lost.

1.4.1 Manual IP Address Setup

By default, your HT-EMN2’s local IP address is 192.168.0.254. If your HT-EMN2 is using the default IP address, you should set your computer’s IP address to be between 192.168.0.1 and 192.168.0.253.

WIRELESS OVERVIEW



2Wireless overviewThis section describes some of the concepts related to the 2.4G and 5G Wireless screens.

2.1 Wireless Networking Basics

Your HT-EMN2’s wireless network is part of the Local Area Network (LAN), known as the Wireless LAN (WLAN). The WLAN is a network of radio links between the HT-EMN2 and the other computers and devices that connect to it.

2.2 Architecture

The wireless network consists of two types of device: access points (APs) and clients.

The access point controls the network, providing a wireless connection to each client.

The wireless clients connect to the access point in order to receive a wireless connection to the WAN and the wired LAN.

The HT-EMN2 is the access point, and the computers you connect to the HT-EMN2 are the wireless clients.

WIRELESS OVERVIEW



2.3 Wireless Standards

The way in which wireless devices communicate with one another is standardized by the Institute of Electrical and Electronics Engineers (IEEE). The IEEE standards pertaining to wireless LANs are identified by their 802.11 designation. There are a variety of WLAN standards, but the HT-EMN2 supports the following (in order of adoption - old to new - and data transfer speeds - low to high):

IEEE 802.11b (2.4G)

IEEE 802.11g (2.4G)

IEEE 802.11n (2.4G/ 5G)

IEEE 802.11ac (5G only)

2.4 Service Sets and SSIDs

Each wireless network, including all the devices that comprise it, is known as a Service Set.

NOTE: Depending on its capabilities and configuration, a single wireless access point may control multiple Service Sets; this is often done to provide different service or security levels to different clients.

Each Service Set is identified by a Service Set IDentifier (SSID). This is the name of the network. Wireless clients must know the SSID in order to be able to connect to the AP. You can configure the HT-EMN2 to broadcast the SSID (in which case, any client who scans the airwaves can discover the SSID), or to “hide” the SSID (in which case it is not broadcast, and only users who already know the SSID can connect).

2.5 Wireless Security

Radio is inherently an insecure medium, since it can be intercepted by anybody in the coverage area with a radio receiver. Therefore, a variety of techniques exist to control authentication (identifying who should be allowed to join the network) and encryption (signal scrambling so that only authenticated users can decode the transmitted data). The sophistication of each security method varies, as does its effectiveness. The HT-EMN2 supports the following wireless security protocols (in order of effectiveness):

WIRELESS OVERVIEW



WEP (the Wired Equivalency Protocol): this protocol uses a series of “keys” or data strings to authenticate the wireless client with the AP, and to encrypt data sent over the wireless link. WEP is a deprecated protocol, and should only be used when it is the only security standard supported by the wireless clients. WEP provides only a nominal level of security, since widely-available software exists that can break it in a matter of minutes.

WPA-PSK (WiFi Protected Access - Pre-Shared Key): WPA was created to solve the inadequacies of WEP. There are two types of WPA: the “enterprise” version (known simply as WPA) requires the use of a central authentication database server, whereas the “personal” version (supported by the HT-EMN2) allows users to authenticate using a “pre-shared key” or password instead. While WPA provides good security, it is still vulnerable to “brute force” password-guessing attempts (in which an attacker simply barrages the AP with join requests using different passwords), so for optimal security it is advised that you use a random password of thirteen characters or more, containing no “dictionary” words.

WPA2-PSK: WPA2 is an improvement on WPA. The primary difference is that WPA uses the Temporal Key Integrity Protocol (TKIP) encryption standard (which has been shown to have certain possible weaknesses), whereas WPA2 uses the stronger Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP), which has received the US government’s seal of approval for communications up to the Top Secret security level. Since WPA2-PSK uses the same pre-shared key mechanism as WPA-PSK, the same caveat against using insecure or simple passwords applies.

2.5.1 WPS

WiFi-Protected Setup (WPS) is a standardized method of allowing wireless devices to quickly and easily join wireless networks, while maintaining a good level of security. The HT-EMN2 provides two methods of WPS authentication:

Push-Button Configuration (PBC): when the user presses the PBC button on the AP (either a physical button, or a virtual button in the GUI), any user of a wireless client that supports WPS can press the corresponding PBC button on the client within two minutes to join the network.

Personal Identification Number (PIN) Configuration: all WPS-capable devices possess a PIN (usually to be found printed on a sticker on the device’s housing). When you configure another device to use the same PIN, the two devices authenticate with one another.

WIRELESS OVERVIEW



Once authenticated, devices that have joined a network via WPS use the WPA2 security standard.

2.6 Guest Networks

Your HT-EMN2 supports the creation of a wireless guest network. A guest network enables you to allow temporary visitors to access your wireless Internet connection without revealing your primary network password(s). Computers connected to the guest network can access the Internet connection only, and have no access to other computers or devices on the wireless or wired network.

2.7 MAC Addresses

Every network device possesses a Media Access Control (MAC) address. This is a unique alphanumeric code, given to the device at the factory, which in most cases cannot be changed (although some devices are capable of “MAC spoofing”, where they impersonate another device’s MAC address).

MAC addresses are the most reliable way of identifying network devices, since IP addresses tend to change over time (whether manually altered, or updated via DHCP).

Each MAC address displays as six groups of two hexadecimal digits separated by colons (or, occasionally, dashes) for example 00:AA:FF:1A:B5:74.

NOTE: Each group of two hexadecimal digits is known as an “octet”, since it represents eight bits.

Bear in mind that a MAC address does not precisely represent a computer on your network (or elsewhere), it represents a network device, which may be part of a computer (or other device). For example, if a single computer has an Ethernet card (to connect to your HT-EMN2 via one of the LAN ports) and also has a wireless card (to connect to your HT-EMN2 over the wireless interface) the MAC addresses of the two cards will be different. In the case of the HT-EMN2, each internal module (cable modem module, Ethernet module, wireless module, etc.) possesses its own MAC address.

WIRELESS OVERVIEW



2.8 Wireless Device Filtering

Every networking device has a unique Media Access Control (MAC) address that uniquely identifies it on the network. When you enable MAC address filtering on the HT-EMN2’s wireless network, you can set up a list of devices, identified by their MAC addresses, and deny them access to the HT-EMN2’s wireless network.

MOCA



5MoCAThis chapter describes the screens that display when you click MoCA in the toolbar. It contains the following sections:

MoCA Overview on page 41

The MoCA Information Screen on page 44

The MoCA Setup Screen on page 45

5.1 MoCA Overview

This section describes some of the concepts related to the MoCA screens.

5.1.1 The Multimedia over Coax Alliance

The Multimedia over Coax Alliance (MoCA) is a non-profit technology alliance, which defines a set of specifications for the delivery of high-speed data, such as HD video, over your building’s existing co-axial cabling network. Co-axial, or coax (pronounced “ko-axe”) cable is already incorporated into most buildings for the transmission of RF signals, traditionally for relaying television broadcasts from a TV antenna, satellite or cable box to individual televisions around the building.

MoCA devices allow you use the coax cable network as an extension of your building’s existing IP network, which includes both wired (Ethernet) and wireless (WiFi) traffic. Because they bridge the two networks, they are known as Ethernet-to-Coax Bridges, or ECBs.

MOCA



Figure 14: Bridging the Gap Between IP and Coaxial Networks

MoCA traffic on the coax network does not interfere with existing broadcasts from cable, telco, IPTV or satellite service providers, as it makes use of a previously-unused segment of the RF spectrum. The medium is ideal for real-time applications, providing high data throughput (100Mbps~1Gbps) with low latency, jitter or data loss. Also, coax cabling is generally better-shielded than IP networking media, especially wireless.

Applications to which MoCA networking is well-suited include:

Video on Demand (VoD)

Multi-room, multi-camera Digital Video Recording (DVR)

Gaming (LAN or online multiplayer)

Internet video

Home automation

Video conferencing

5.1.1.1 Horizontal vs. Vertical CommunicationsUnlike traditional coax networking (TV, satellite, IPTV, etc.) MoCA devices do not need to receive data from a single source. It is “outlet-to-outlet”. Each MoCA network uses a Network Controller (NC) to manage the network’s communications, but any ECB on the network is capable of acting as the NC. By default, the NC is chosen by negotiation between all ECBs on the network, based on factors such as signal strength.

MOCA



“Outlet-to-outlet” communications are also known as “splitter jumping”. Traditional cable networking commonly utilized splitters to split a single incoming signal into two outgoing signals. With MoCA, communications between devices connected to each splitter output are possible. For this reason, MoCA communications can be considered “horizontal”, as opposed to traditional “vertical” cable communications.

Figure 15: Traditional Vertical CATV vs. Horizontal MoCA Networking

5.1.1.2 Example MoCA Mesh NetworkMoCA devices form a full “mesh”, or peer-to-peer network (where all devices communicate directly with one another). In the following example, four MoCA devices connect directly to and from one another, via ECBs, forming 12 unique MoCA links (or 6 bidirectional links).

MOCA



Figure 16: Example MoCA Peer-to-Peer Network

5.2 The MoCA Information Screen

5.3 The MoCA Setup Screen

Use this screen to view and make changes to the HT-EMN2’s cable network settings.

NOTE: Do not change any of the settings in this screen unless you have a good reason to do so!

Click MoCA > MoCA Setup. The following screen displays.

Figure 18: The MoCA: MoCA Setup Screen


Link Status This displays whether or not the HT-EMN2 is connected over the cable network.

Coax TX This displays the transmission (TX) power of the HT-EMN2 on the cable network, from 0 (extremely weak) to 10 (extremely strong).

Coax RX This displays the strength of the signal that the HT-EMN2 is receiving (RX) on the cable network, from 0 (extremely weak) to 10 (extremely strong).

Table 13: The MoCA: Coax Settings Screen Network Search Use this to Enable or Disable MoCA function.Last Operating Frequency

Use this to set operation frequency of MoCA.

Table 12: The MoCA: MoCA Information Screen (continued)

MOCA



TxPower Level Use this field to set the power at which the HT-EMN2 transmits (TX) over the cable network, from 0 to 10.

Beacon Power Level Use this field to set the HT-EMN2’s beacon power on the cable network, from 0 to 10. The MoCA beacon allows other devices on the cable network to detect the HT-EMN2.

Preferred NC Each MoCA network has a Network Coordinator (NC) which acts as a manager for all the other devices on the cable network.By default, the NC is chosen from the pool of MoCA

devices based on its suitability (signal strength, etc.) To base NC status on merit, or if you have specified another device as “preferred” and do not want the HT-EMN2 to compete with it, select Auto-negotiated.

When one device is set to be the “preferred” NC, it will be the NC whenever it is available on the network (if multiple devices are “preferred”, the most suitable one will be chosen). Select Preferred to add the HT-EMN2 to the preferred group.

Channel Plan The MoCA specification defines several channel plans for communication on the cable network (see MoCA Overview on page 41). This field allows you to select the channel plan that you want the HT-EMN2 to use.

Select the channel plan that you wish to use from the dropdown list.

Figure 19: Channel Plan Options

Security Select Enabled to turn MoCA security on. Only MoCA devices configured to use the Password you define can access the network.

Select Disabled to turn MoCA security off. Any MoCA device can access the network.

TROUBLESHOOTING



6TroubleshootingUse this section to solve common problems with the HT-EMN2 and your network. It contains the following sections:

None of the LEDs Turn On on page 48

One of the LEDs does not Display as Expected on page 49

I Forgot the HT-EMN2’s IP Address on page 49

I Forgot the HT-EMN2’s Admin Username or Password on page 49

I Cannot Access the HT-EMN2 or the Internet on page 49

I Cannot Connect My Wireless Device on page 50

Problem: None of the LEDs Turn On

The HT-EMN2 is not receiving power, or there is a fault with the device.

1 Ensure that you are using the correct power adaptor.

Using a power adaptor other than the one that came with your HT-EMN2 can damage the HT-EMN2.

2 Ensure that the power adaptor is connected to the HT-EMN2 and the wall socket (or other power source) correctly.

3 Ensure that the power source is functioning correctly. Replace any broken fuses or reset any tripped circuit breakers.

4 Disconnect and re-connect the power adaptor to the power source and the HT-EMN2.

TROUBLESHOOTING



5 If none of the above steps solve the problem, consult your vendor.

Problem: One of the LEDs does not Display as Expected

1 Ensure that you understand the LED’s normal behavior (see LEDs on page 13).

2 Ensure that the HT-EMN2’s hardware is connected correctly; see the Quick Installation Guide.

3 Disconnect and re-connect the power adaptor to the HT-EMN2.

4 If none of the above steps solve the problem, consult your vendor.

Problem: I Forgot the HT-EMN2’s IP Address

1 The HT-EMN2’s default LAN IP address is 192.168.0.254.

2 If you once changed the defalt IP address, press reset button more rhan 5 seconds to set HT-EMN2 back to factory defalt setting.

3 Depending on your operating system and your network, you may be able to find the HT-EMN2’s IP address by looking up your computer’s default gateway. To do this on (most) Windows machines, click Start > Run, enter “cmd”, and then enter “ipconfig”. Get the IP address of the Default Gateway, and enter it in your browser’s address bar.

Problem: I Forgot the HT-EMN2’s Admin Username or Password

The default username is cusadmin, and the default password is password.

Problem: I Cannot Access the HT-EMN2 or the Internet

1 Ensure that you are using the correct IP address for the HT-EMN2.

2 Check your network’s hardware connections, and that the HT-EMN2’s LEDs display correctly (see LEDs on page 13).

3 Make sure that your computer is on the same subnet as the HT-EMN2; see IP Address Setup on page 16.

TROUBLESHOOTING



4 If you are attempting to connect over the wireless network, there may be a problem with the wireless connection. Connect via a LAN port instead.

5 If the above steps do not work, you need to reset the HT-EMN2. See The Summary Screen on page 19. All user-configured data is lost, and the HT-EMN2 is returned to its default settings. If you previously backed-up a more recent version your HT-EMN2’s settings, you can now upload them to the HT-EMN2; see The Backup Screen on page 82.

6 If the problem persists, contact your vendor.

Problem: I Cannot Connect My Wireless Device

1 Ensure that your wireless client device is functioning properly, and is configured correctly. See the wireless client’s documentation if unsure.

2 Ensure that the wireless client is within the HT-EMN2’s radio coverage area. Bear in mind that physical obstructions (walls, floors, trees, etc.) and electrical interference (other radio transmitters, microwave ovens, etc) reduce your HT-EMN2’s signal quality and coverage area.

3 Ensure that the HT-EMN2 and the wireless client are set to use the same wireless mode, SSID and security settings (see The Basic Screen on page 27 and The following table describes the labels in this screen. on page 32).

4 Re-enter any security credentials (WEP keys, WPA(2)-PSK password, or WPS PIN).

5 If you are using WPS’s PBC (push-button configuration) feature, ensure that you are pressing the button on the HT-EMN2 and the button on the wireless client within 2 minutes of one another.
