Ethernet or Wireless?

There are two ways to connect your computer (or other equipment) to the Telephony Modem. The following will help you decide which is best for you:

Ethernet

Ethernet is a standard method of connecting two or more computers into a Local Area Network (LAN). You can use the Ethernet connection if your computer has built-in Ethernet hardware.

Note: To connect more than four computers to the WTM652 through the Eth-

ernet ports, you need an Ethernet hub (available at computer retailers).

The Telephony Modem package comes with one 6-foot (1.9m) Ethernet cable (the connectors look like wide telephone connectors); you can purchase more cables if necessary at a computer retailer. If you are connecting the Telephony Modem directly to a computer, or to an Ethernet hub with a cross-over switch, ask for Category 5 (CAT5) straight-through cable. If you are connecting the Telephony Modem to an Ethernet hub without a crossover switch, ask for a Category 5 crossover cable.

Ethernet Cable

Wireless

The 802.11 wireless LAN standard allows one or more computers to access the WTM652 using a wireless (radio) signal. You can use the wireless connection if your computer has a built-in or aftermarket wireless card.

Note: To learn more about which wireless hardware works best with your com-

puter, see your computer dealer.

Both

If you have two or more computers, you can use Ethernet for up to four devices and wireless for others. To connect ﬁve or more computers to the Ethernet ports, you will need an Ethernet hub (available at computer retailers).

For more information about connecting two or more computers, contact your cable service provider.

What About Security?

Having a high-speed, always-on connection to the Internet requires a certain amount of responsibility to other Internet users—including the need to maintain a reasonably secure system. While no system is 100% secure, you can use the following tips to enhance your system’s security:

• Keep your operating system updated with the latest security patches. Run the system update utility at least weekly.

• Keep your email program updated with the latest security patches. In addition, avoid opening email containing attachments, or opening ﬁles sent through chat rooms, whenever possible.

• Install a virus checker and keep it updated.

• Avoid providing web or ﬁle-sharing services over your Telephony Modem. Besides certain vulnerability problems, most cable companies prohibit running servers on consumer-level accounts and may suspend your account for violating your terms of service.

• Use the cable company’s mail servers for sending email.

• Avoid using proxy

software unless you are certain that it is not open for abuse by other Internet users (some are shipped open by default). Criminals can take advantage of open proxies to hide their identity when breaking into other computers or sending spam. If you have an open proxy, your cable company may suspend your account to protect the rest of the network.

• If you use the wireless LAN, make sure you enable wireless security on the Telephony Modem (for the same reasons that you should run only secured proxies). See “Wireless Conﬁguration” for help.

Selecting an Installation Location

There are a number of factors to consider when choosing a location to install your Telephony Modem:

• Is an AC outlet available nearby? For best results, the outlet should not be switched and should be close enough to the Telephony Modem that extension cords are not required.

• Is a cable jack available? For best performance, keep the number of splitters between the jack and cable drop to a minimum. Each splitter attenuates (reduces) the signal available to the Telephony Modem. A large number of splitters can slow down the Internet connection and even affect your telephone service.

• Can you easily run cables between the Telephony Modem’s location and the phones?

• If you are connecting devices to the Ethernet ports, can you easily run cables between the Telephony Modem’s location and those devices?

• If you want to mount the Telephony Modem on a wall, does the location provide a solid surface for secure attachment? For best results when mounting the Telephony Modem on drywall, position the Telephony Modem so at least one of the screws are fastened to a stud. This may prevent the Telephony Modem from pulling out of the wall in the future.

• If you want to install the Telephony Modem on a desktop, is there enough space on either side to keep the vents clear? Blocking the vents may cause overheating.

• How close are your wireless devices? The Telephony Modem wireless connection range is typically 100–200 feet (30m–65m). A number of factors can affect connection range, as described below.

Conﬁguration Usage Troubleshooting Glossary

Factors Affecting Wireless Range

A number of factors can affect the usable range for wireless connections.

Increases range: • Raising the antenna above the devices (for example,

installing the Telephony Modem in the upper ﬂoor of a multi-story dwelling or using an aftermarket omnidirectional antenna)

• Using an aftermarket directional antenna (increases range in one direction while decreasing range in other directions)

• Adding wireless hubs in a bridge (WDS) network

Decreases range: • Lowering the antenna below the devices (for example,

installing the Telephony Modem in a basement)

• Removing the antenna

• Metal or concrete walls between the Telephony Modem and other devices

• Large metal appliances, aquariums, or metal cabinets between the Telephony Modem and other devices

• Interference and RF noise (2.4 GHz wireless phones, microwave ovens, or other wireless networks)

Note that decreasing the range of your wireless network may be beneﬁcial, as long as the decreased range is sufﬁcient for your needs. By limiting your network’s range, you reduce interference with other networks and make it harder for unwanted users to ﬁnd and connect to your network.

Step 2

Step 4

For wall-mounted installations, make sure you have the following tools and materials before proceeding:

• for mounting on drywall: Two 1/4” (6mm) drywall anchors and a drill with 1/4” (6mm) bit (not included)

• for mounting on plywood or studs: two #6 x 1.5” (38.1 mm) self tapping screws (included)

• screwdriver (ﬂat-blade or Phillips, depending on what kind of screws you use)

• wall-mount template (included)

• transparent tape (for temporarily securing the mounting template to the wall)

Wall-mounting instructions

1 Position the mounting template on the surface where you intend to mount

the Telephony Modem and secure in place with transparent tape.

2 Drill holes through the template in the speciﬁed locations for the mounting

screws. After drilling holes, remove the template from the surface.

3 If using drywall anchors, set them into the wall. Then, drive the screws into

the wall leaving a gap of about 1/8” (3 mm) between the screw head and the wall. If not using anchors, just drive the screws.

Conﬁguring the Firewall

The WTM652 provides a ﬁrewall to protect the computers on your home network from unwanted access. The ﬁrewall provides the following features:

• Virtual Server Support: if you have a server on your home network that you want to make available to the general Internet, you can conﬁgure a virtual server. The ﬁrewall passes requests from the Internet to the designated computer on your home network.

• Client ﬁlters: you can use client ﬁlters to block computers on your network from accessing the Internet (or certain services) during speciﬁc days and times.

• MAC Address ﬁltering: allows access to the wireless network only by computers speciﬁcally authorized to connect.

• Ping blocking: ignores ICMP (Ping) requests from the Internet.

Note: Your domain name may not be immediately associated with your cur-

rent IP address. Updated DNS information takes some time to propagate across the Internet.

5 Proceed to Conﬁguring Wireless Bridging

Conﬁguring Wireless Bridging

The Telephony Modem supports the Wireless Distribution System (WDS), a common bridging standard that allows you to extend the range of a wireless network by connecting several wireless routers.

Keep the following in mind when setting up wireless bridging:

• One device (in this case, the Telephony Modem) acts as the router. Other wireless routers must be conﬁgured as Access Points. See the documentation for your additional devices for instructions for using them as Access Points.

• While the Telephony Modem has the ability to be conﬁgured as an Access Point, doing so disables the router function and therefore disables Internet access through the Telephony Modem.

• Each wireless router must support WDS.

• The Router and each Access Point must use the same channel number and security settings.

• If MAC address ﬁltering is enabled, the router and each Access Point must have the MAC addresses of the other devices in their access lists.

Follow these steps to set up wireless bridging. The steps assume you have already conﬁgured the devices as described above.

Resetting the Telephony Modem Router

The router can be reset in two ways: a “normal” reset that simply restarts the router (without affecting any phone calls in progress), and a “factory” reset that erases the current conﬁguration to the factory defaults.

Restarting the Router

To restart the router, you can push the Router Reset button on the back of the Telephony Modem. If your Telephony Modem is mounted in an inconvenient location, or you need to restart it remotely, you can use the Restart Router page.

To restart the router remotely, click the Utilities link in the navigation menu, then click Restart Router. When the page appears, click the Restart Router button. The Telephony Modem shows a conﬁrmation dialog; click OK to restart the router.

Resetting the Router to Factory Defaults

To reset the router to factory defaults, you can press and hold the Router Reset button on the back of the Telephony Modem for about eight seconds. You may need to do this if a misconﬁguration has locked out all access. If you can access the router and want to restart it remotely, you can use the Restore Factory Defaults page.

To restore factory defaults remotely, click the Utilities link in the navigation menu, then click Restore Factory Defaults. When the page appears, click the Restore Defaults button. The Telephony Modem shows a conﬁrmation dialog; click OK to erase the conﬁguration to factory defaults.

The router resets itself after erasing the current conﬁguration. Note: If you want to restore the current conﬁguration after restoring factory

defaults, see Backing Up and Restoring the Conﬁguration

General Problems and Solutions

The Telephony Modem is plugged in, but the Power light is off.

Check all power connections. Is the power cord plugged in ﬁrmly at both ends?

If you plugged the power cord into a power strip, make sure the strip is switched on.

Avoid using an outlet controlled by a wall switch, if possible. Finally, check the fuse or circuit breaker panel.

I’m not getting on the Internet (all connections).

It may take over 30 minutes to establish a connection the ﬁrst time you power up your Telephony Modem, especially when many people are online. Always leave your Telephony Modem plugged into AC power and connected to the cable system.

Check the front panel lights:

• The Power and Online lights should be on.

• The Link light should be either on or blinking.

• If the Power light blinks for more than 30 minutes, call your cable company for assistance.

Check your cable connections. Connectors should be ﬁnger-tight. The coax

cable should not be pinched, kinked, or bent sharply—any of these can cause

a break or short in the cable (you may have to replace the cable). If you have one or more splitters between the Telephony Modem and CATV outlet, remove the splitters and connect the Telephony Modem directly to the outlet.

Proceed to the Ethernet or wireless solutions (next page) if necessary.

I don’t have dial tone when I pick up my phone, why?

In order for telephone service to be functional on the Telephony Modem, telephone service must have been purchased from the service provider and conﬁgured on your Telephony Modem. The following steps should help in identifying the source of the problem.

1 Is the Power LED lit?

• If not, check to make sure the Telephony Modem is plugged in and the outlet has power.

• If the LED is lit, go to the next step.

2 Is the Online LED lit?

• If not, check the coax connection at the Telephony Modem and the wall. Ensure they are connected and tight. If they are and you do not have dial tone, contact your service provider.

• If the Online LED is lit, go to the next step.

3 Is the Telephone (Telephone 1 or Telephone 2) LED lit?

• If not, phone service has not been set up on that line. Contact your service provider.

• If it is blinking, there is a phone off hook somewhere in the house. Find that phone and hang it up.

• If it is lit, go to the next step.

4 Is the phone plugged directly into the Telephony Modem?

• Make sure the phone is plugged into the port on the back of the Telephony Modem labeled “Tel 1” for line 1, and “Tel 2” for line 2.

• If so, try a different phone. Make sure the new phone is a working phone.

• If a known good phone is used and you still don’t have dial tone, try a different phone cable. If a new phone and cable do not restore dial tone, call your service provider.
