Section 1 - Product Overview
Introduction
The eHome Wireless G EH100 Router is capable of transferring data with a maximum wireless signal rate of up to
54Mbps* in the 2.4GHz frequency — the same wireless frequency as 802.11b. The eHome EH100 Wireless Router
also offers four Ethernet ports to support multiple computers.
The advanced wireless technology built into the EH100 Wireless Router offers data transfer speeds with a maximum
wireless signal rate of up to 54Mbps* through its wireless channels allowing streaming videos and other high bandwidth
applications, such as online gaming events, to operate without the hassle of Ethernet cables. The ability to use high
bandwidth applications also makes streaming real-time programs more enjoyable and more efficient.
With the EH100 Wireless Router’s built-in advanced firewall, threats of hackers penetrating your network are minimized.
Some firewall features include functions that allow or disallow certain ports to be open for certain applications. Time
scheduling can be established as a firewall rule so that specific ports will be open at certain times and be closed at
other times. Features like MAC filtering, URL blocking, and domain blocking are useful tools to prevent other unwanted
intruders from connecting to your network or browsing restricted sites.
The easy-to-use configuration wizard takes only minutes to setup and guides users step-by-step through configuring
the EH100. With all the versatile features and an user-friendly utility, the EH100 Wireless Router provides an enhanced
networking experience.
* Maximum wireless signal rate derived from IEEE Standard 802.11g specifications. Actual data throughput will vary. Network conditions and
environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput
rate. Environmental conditions will adversely affect wireless signal range.

gives you the freedom of wireless networking at speeds 5x faster than 802.11b.
• Compatible with 802.11b and 802.11g Devices - The EH100 is still fully compatible with the IEEE
802.11b standard, so it can connect with existing 802.11b PCI, USB and Cardbus adapters.
• Advanced Firewall Features - The Web-based user interface displays a number of advanced network
management features including:
• Content Filtering - Easily applied content filtering based on MAC Address, IP Address, URL,
and/or Domain Name.
Features
• Filter Scheduling - These filters can be scheduled to be active on certain days or for a
duration of hours or minutes.
• Secure Multiple/Concurrent Sessions - The EH100 can pass through VPN sessions. It
supports multiple and concurrent IPSec and PPTP sessions, so users behind the EH100 can
securely access corporate networks.
• User-friendly Setup Wizard - Through its easy-to-use Web-based user interface, the EH100 lets you
control what information is accessible to those on the wireless network, whether from the Internet or from
your company’s server. Configure your router to your specific settings within minutes.

Section 2 - Installation
Installation
This section will walk you through the installation process. Placement of the router is very important. Do not place the
router in an enclosed area such as a closet, cabinet, or in the attic or garage.
Before you Begin
Please configure the router with the computer that was last connected directly to your modem. Also, you can only use
the Ethernet port on your modem. If you were using the USB connection before using the router, then you must turn off
your modem, disconnect the USB cable and connect an Ethernet cable to the WAN port on the router, and then turn
the modem back on. In some cases, you may need to call your ISP to change connection types (USB to Ethernet).
If you have DSL and are connecting via PPPoE, make sure you disable or uninstall any PPPoE software such as
WinPoet, Broadjump, or Enternet 300 from your computer or you will not be able to connect to the Internet.

Section 2 - Installation
Wireless Installation Considerations
The eHome wireless router lets you access your network using a wireless connection from virtually anywhere within
the operating range of your wireless network. Keep in mind, however, that the number, thickness and location of walls,
ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending
on the types of materials and background RF (radio frequency) noise in your home or business. The key to maximizing
wireless range is to follow these basic guidelines:
1. Keep the number of walls and ceilings between the eHome router and other network devices to a
minimum - each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position
your devices so that the number of walls or ceilings is minimized.
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a
45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet
(14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead
of at an angle) for better reception.
3. Building Materials make a difference. A solid metal door or aluminum studs may have a negative effect on
range. Try to position access points, wireless routers, and computers so that the signal passes through
drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water
(fish tanks), mirrors, file cabinets, brick, and concrete will degrade your wireless signal.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that
generate RF noise.
5. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and
home security systems), your wireless connection may degrade dramatically or drop completely. Make
sure your 2.4GHz phone base is as far away from your wireless devices as possible. The base transmits
a signal even if the phone in not in use.

Section 2 - Installation
Connect to Cable/DSL/Satellite Modem
If you are connecting the router to a cable/DSL/satellite modem, please follow the steps below:
1. Place the router in an open and central location. Do not plug the power adapter into the router.
2. Turn the power off on your modem. If there is no on/off switch, then unplug the modem’s power adapter. Shut down
your computer.
3. Unplug the Ethernet cable (that connects your computer to your modem) from your computer and place it into the
WAN port on the router.
4. Plug an Ethernet cable into one of the four LAN ports on the router. Plug the other end into the Ethernet port on your
computer.
5. Turn on or plug in your modem. Wait for the modem to boot (about 30 seconds).
6. Plug the power adapter to the router and connect to an outlet or power strip. Wait about 30 seconds for the router
to boot.
7. Turn on your computer.
8. Verify the link lights on the router. The power light, WAN light, and the LAN light (the port that your computer is
plugged into) should be lit. If not, make sure your computer, modem, and router are powered on and verify the cable
connections are correct.
9. Skip to page 14 to configure your router.

Section 2 - Installation
Connect to Another Router
If you are connecting the eHome router to another router to use as a wireless access point and/or switch, you will have
to do the following before connecting the router to your network:
• Disable UPnP
• Disable DHCP
• Change the LAN IP address to an available address on your network. The LAN ports on the router cannot
accept a DHCP address from your other router.
To connect to another router, please follow the steps below:
1. Plug the power into the router. Connect one of your computers to the router (LAN port) using an Ethernet cable.
Make sure your IP address on the computer is 192.168.0.xxx (where xxx is between 2 and 254). Please see the
Networking Basics section for more information. If you need to change the settings, write down your existing settings
before making any changes. In most cases, your computer should be set to receive an IP address automatically in
which case you will not have to do anything to your computer.
2. Open a web browser and enter http://192.168.0.1 and press Enter. When the login window appears, set the user
name to admin and leave the password box empty. Click OK to continue.
3. Browse to the Advanced > Advanced Network page. Uncheck the box next to Enable UPnP. Click the Save Settings button to continue.
™
4. Browse to the Setup > Network Settings page. Uncheck the box next to Enable DHCP Server.
5. Under Router Settings, enter an available IP address and the subnet mask of your network. Click Save Settings
to save your settings. Use this new IP address to access the configuration utility of the router in the future. Close the
browser and change your computer’s IP settings back to the original values as in Step 1.

Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The
EH100 offers the following types of security:
WEP stands for Wired Equivalent Privacy. It is based on the IEEE 802.11 standard and uses the RC4 encryption
algorithm. WEP provides security by encrypting data over your wireless network so that it is protected as it is transmitted
from one wireless device to another.
To gain access to a WEP network, you must know the key. The key is a string of characters that you create. When using
WEP, you must determine the level of encryption. The type of encryption determines the key length. 128-bit encryption
requires a longer key than 64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal - using
characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange – alphanumeric characters) format.
ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is converted to HEX
for use over the network. Four keys can be defined so that you can change keys easily.

Section 4 - Security
What is WPA?
WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (Wired
Equivalent Privacy).
The 2 major improvements over WEP:
• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys
using a hashing algorithm and, by adding an integrity-checking feature, ensures that the keys haven’t
been tampered with. WPA2 is based on 802.11i and uses Advanced Encryption Standard (AES) instead
of TKIP.
• User authentication, which is generally missing in WEP, through the extensible authentication protocol
(EAP). WEP regulates access to a wireless network based on a computer’s hardware-specific MAC
address, which is relatively simple to be sniffed out and stolen. EAP is built on a more secure public-key
encryption system to ensure that only authorized network users can access the network.
WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric
password between 8 and 63 characters long. The password can include symbols (!?*&_) and spaces. This key must
be the exact same key entered on your wireless router or access point.
WPA/WPA2 incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on a
more secure public key encryption system to ensure that only authorized network users can access the network.

3. Why can’t I connect to certain sites or send and receive emails when connecting through my router?
If you are having a problem sending or receiving email, or connecting to secure sites such as eBay, banking sites, and
Hotmail, we suggest lowering the MTU in increments of ten (Ex. 1492, 1482, 1472, etc).
Note: AOL DSL+ users must use MTU of 1400.
To find the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination could
be another computer, or a URL.
• Click on Start and then click Run.
• Windows® 95, 98, and ME users type in command (Windows® NT, 2000, and XP users type in cmd) and
press Enter (or click OK).
• Once the window opens, you’ll need to do a special ping. Use the following syntax:
ping [url] [-f] [-l] [MTU value]
Example: ping yahoo.com -f -l 1472
76eHome EH100 User Manual
Section 6 - Troubleshooting
You should start at 1472 and work your way down by 10 each time. Once you get a reply, go up by 2 until you get a
fragmented packet. Take that value and add 28 to the value to account for the various TCP/IP headers. For example,
lets say that 1452 was the proper value, the actual MTU size would be 1480, which is the optimum for the network
we’re working with (1452+28=1480).
Once you find your MTU, you can now configure your router with the proper MTU size.
To change the MTU rate on your router follow the steps below:
• Open your browser, enter the IP address of your router (192.168.0.1) and click OK.
• Enter your username (admin) and password (blank by default). Click OK to enter the web configuration
page for the device.
• Click on the Home tab and click the WAN button.
• To change the MTU enter the number in the MTU field and click the Apply button to save your settings.
• Test your email. If changing the MTU does not resolve the problem, continue changing the MTU in
increments of ten.

A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals
instead of wires. Wireless LANs are used increasingly in both home and office environments, and public areas such
as airports, coffee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and
communicate more efficiently. Increased mobility and the absence of cabling and other fixed infrastructure have proven
to be beneficial for many users.
Wireless users can use the same applications they use on a wired network. Wireless adapter cards used on laptop
and desktop systems support the same protocols as Ethernet adapter cards.
Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in
order to use servers, printers or an Internet connection supplied through the wired LAN. A Wireless Router is a device

What is Wireless?
Wireless or Wi-Fi technology is another way of connecting your computer to the network without using wires. Wi-Fi
uses radio frequency to connect wirelessly, so you have the freedom to connect computers anywhere in your home or
office network.
How does wireless work?
Wireless works similar to how cordless phone work, through radio signals to transmit data from one point A to point
B. But wireless technology has restrictions as to how you can access the network. You must be within the wireless
network range area to be able to connect your computer. There are two different types of wireless networks Wireless
Local Area Network (WLAN), and Wireless Personal Area Network (WPAN).
Wireless Local Area Network (WLAN)
In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access
point has a small antenna attached to it, which allows it to transmit data back and forth over radio signals. With an
indoor access point as seen in the picture, the signal can travel up to 300 feet. With an outdoor access point the signal
can reach out up to 30 miles to serve places like manufacturing plants, industrial locations, college and high school
campuses, airports, golf courses, and many other outdoor venues.
Wireless Personal Area Network (WPAN)
Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate in a range
up to 30 feet away.
Compared to WLAN the speed and wireless operation range are both less than WLAN, but in return it doesn’t use

Appendix A - Wireless Basics
Where is wireless used?
Wireless technology is expanding everywhere not just at home or office. People like the freedom of mobility and it’s
becoming so popular that more and more public facilities now provide wireless access to attract people. The wireless
connection in public places is usually called “hotspots”.
Using a eHome Cardbus Adapter with your laptop, you can access the hotspot to connect to Internet from remote
locations like Airports, Hotels, Coffee Shops, Libraries, Restaurants, and Convention Centers.
Wireless network is easy to setup, but if you’re installing it for the first time it could be quite a task not knowing where to
start. That’s why we’ve put together a few setup steps and tips to help you through the process of setting up a wireless
network.
Tips
Here are a few things to keep in mind, when you install a wireless network.
Centralize your router or Access Point
Make sure you place the router/access point in a centralized location within your network for the best performance. Try
to place the router/access point as high as possible in the room, so the signal gets dispersed throughout your home.
If you have a two-story home, you may need a repeater to boost the signal to extend the range.
Eliminate Interference
Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible from the
router/access point. This would significantly reduce any interference that the appliances might cause since they operate
on same frequency.

Appendix A - Wireless Basics
Security
Don’t let you next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning
on the WPA or WEP security feature on the router. Refer to product manual for detail information on how to set it up.
Wireless Modes
There are basically two modes of networking:
• Infrastructure – All wireless clients will connect to an access point or wireless router.
• Ad-Hoc – Directly connecting to another computer, for peer-to-peer communication, using wireless
network adapters on each computer.
An Infrastructure network contains an Access Point or wireless router. All the wireless devices, or clients, will connect
to the wireless router or access point.
An Ad-Hoc network contains only clients, such as laptops with wireless cardbus adapters. All the adapters must be in
Ad-Hoc mode to communicate.

Networking Basics
Check your IP address
After you install your network adapter, by default, the TCP/IP settings should be set to obtain an IP address from a
DHCP server (i.e. wireless router) automatically. To verify your IP address, please follow the steps below.
Click on Start > Run. In the run box type cmd and click OK.
At the prompt, type ipconfig and press Enter.
This will display the IP address, subnet mask, and
the default gateway of your adapter.
If the address is 0.0.0.0, check your adapter
installation, security settings, and the settings
on your router. Some firewall software programs
may block a DHCP request on newly installed
adapters.
If you are connecting to a wireless network at a hotspot (e.g. hotel, coffee shop, airport), please contact an employee
or administrator to verify their wireless network settings.

Appendix B - Networking Basics
Statically Assign an IP address
If you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps
below:
Step 1
Windows® XP - Click on Start > Control Panel > Network Connections.
Windows® 2000 - From the desktop, right-click My Network Places > Properties.
Step 2
Right-click on the Local Area Connection which represents your network adapter and select Properties.
Step 3
Highlight Internet Protocol (TCP/IP) and click Properties.
Step 4
Click Use the following IP address and enter an IP address that is on the same subnet as your network or the LAN
IP address on your router.
Example: If the router´s LAN IP address is 192.168.0.1, make your IP address
192.168.0.X where X is a number between 2 and 99. Make sure that the number
you choose is not in use on the network. Set Default Gateway the same as the LAN
IP address of your router (192.168.0.1).
Set Primary DNS the same as the LAN IP address of your router (192.168.0.1). The
Secondary DNS is not needed or you may enter a DNS server from your ISP.
