About this ManualThis manual covers the Xfinity TG1682 Telephony Gateway. The model number ison the label affixed to the bottom of the Telephony Gateway.  See the image at theleft.What About Security?Having  a  high-speed,  always-on  connection  to  the  Internet  requires  a  certainamount of responsibility to other Internet users—including the need to maintain areasonably secure system. While no system is 100% secure, you can use the fol-lowing tips to enhance your system’s security:• Keep the operating system of your computer or laptop updated with the lat-est security patches. Run the system update utility at least weekly.• Keep your email program updated with the latest security patches. In addi-tion,  avoid  opening  email  containing  attachments,  or  opening  files  sentthrough chat rooms, whenever possible.• Install a virus checker and keep it updated.• Avoid providing web or file-sharing services over your Telephony Gateway.Besides certain vulnerability problems, most cable companies prohibit run-ning servers on consumer-level accounts and may suspend your account forviolating 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 forabuse by other Internet users (some are shipped open by  default). Crimi-nals can take advantage of open proxies to hide their identity when break-ing into other computers or sending spam. If you have an open proxy, yourca ble company may suspend your account to protect the rest of the net-work.• If you use the wireless LAN, make sure you enable wireless security on theTelephony Gateway (for the same reasons that you should run only securedproxies).

Selecting an Installation LocationThere are a number of factors to consider when choosing a location to install yourTelephony Gateway:• Is an AC outlet available nearby? For best results, the outlet should not beswitched and should be close enough to the Telephony Gateway that exten-sion cords are not required.• Is a cable jack available? For best performance, keep the number of split-ters between the jack and cable drop to a minimum. Each splitter attenuates(re duces) the signal available to the Telephony Gateway. A large number ofsplit ters can slow down the Internet connection and even affect your tele-phone service.• Can you easily run cables between the Telephony Gateway’s location andthe phones?• If you are connecting devices to the Ethernet ports, can you easily run ca-bles between the Telephony Gateway’s location and those devices?• If you want to install the Telephony Gateway on a desktop, is there enoughspace on either side to keep the vents clear? Blocking the vents may causeoverheating.• How close are your wireless devices? The Telephony Gateway wireless con-nection range is typically 100–200 feet (30m–65m). A number of factorscan affect connection range, as described below.Desktop mounting instructionsPosition the Telephony Gateway so that:• air flows freely around it• the back faces the nearest wall• it will not fall to the floor if bumped or moved• the side of the unit are not blocked.Xfinity TG1682 Telephony Gateway User’s GuideSafetyGettingStartedBatteryInstallation InstallationEthernetConfiguration Usage Troubleshooting Glossary20
Cleaning InstructionsClean the Telephony Gateway using only a clean, slightly moistened, cloth. Do notuse aerosols in the vicinity of the Telephony Gateway.Factors Affecting Wireless RangeA number of factors can affect the usable range for wireless connections.Note: Decreasing the range of your wireless network may be beneficial, as longas the decreased range is sufficient for your needs. By limiting your net-work’s range, you reduce interference with other networks and make itharder for unwant ed users to find and connect to your network.Note: Setting the trasmit power level to High increases the range.  Setting itto Medium or Low decreases the range proportionately.Increases range: • Raising the unit above the devices (for example, in-stalling the Telephony Gateway in the upper floor of amulti-story dwelling)• Adding a wireless extender to the networkDecreases range: • Lowering the unit below the devices (for example, in-stalling the Telephony Gateway in a basement)• Metal or concrete walls between the Telephony Gate-way and other devices• Large metal appliances, aquariums, or metal cabinetsbetween the Telephony Gateway and other devices• Interference and RF noise (2.4 GHz wireless phones,microwave ovens, or other wireless networks)Xfinity TG1682 Telephony Gateway User’s GuideSafetyGettingStartedBatteryInstallation InstallationEthernetConfiguration Usage Troubleshooting Glossary21

(Wireless)Check the indicator lights (see Using the Telephony Gateway) — the WiFilight should be on.Does your connection utility discover your wireless LAN? If you turned off“Broadcast SSID” you need to manually enter the name of your wireless LANin the connection utility.Change your security mode to “disabled”. Enable one of the other securitymodes as soon as you find the problem.A misconfiguration could lock out all access to the Telephony Gateway router.If you think this has happened, see Resetting the Router to Factory Defaults.My wireless Internet connection stops working sometimes.This is usually caused by interference — two common sources are 2.4GHz“remote” telephones and microwave ovens. If you cannot remove the inter-fering product, try using a different channel or setting Protected Mode.I can get on the Internet, but everything is slow.If the Web site you are visiting is very popular, that site may be having trou-ble servicing all the requests. If other sites download quickly, wait for a fewminutes and try again. Usage during peak hours may also affect the con nec-tion speed.Other communications on the LAN, or interference with wireless connec-tions, may slow down your connection.Xfinity TG1682 Telephony Gateway User’s GuideSafetyGettingStartedBatteryInstallation InstallationEthernetConfiguration Usage Troubleshooting Glossary36
I don’t have dial tone when I pick up my phone, why?In order for telephone service to be functional on the Telephony Gateway,telephone service must have been purchased from the service provider andconfigured on your Telephony Gateway. The following steps should help inidentifying the source of the problem.1Is the Power LED lit?• If not, check to make sure the Telephony Gateway is plugged inand the outlet has power.• If the LED is lit, go to the next step.2Is the Online LED lit?• If not, check the coax connection at the Telephony Gateway andthe wall. Ensure they are connected and tight. If they are andyou do not have dial tone, contact your service provider.• If the Online LED is lit, go to the next step.3Is the Telephone (Tel 1 or Tel 2) LED lit?• If not, phone service has not been set up on that line. Contactyour service provider.• If  it  is  blinking,  there  is  a  phone  off  hook  somewhere  in  thehouse. Find that phone and hang it up.• If it is lit, go to the next step.4Is the phone plugged directly into the Telephony Gateway?• Make sure the phone is plugged into the port on the back of theTelephony Gateway labeled “Tel 1” for line 1, and “Alarm/Tel 2” forline 2.• If so, try a different phone. Make sure the new phone is a work-ing 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 re-store dial tone, call your service provider.Xfinity TG1682 Telephony Gateway User’s GuideSafetyGettingStartedBatteryInstallation InstallationEthernetConfiguration Usage Troubleshooting Glossary37
5Is the Telephony Gateway plugged into a wall outlet?• If so, unplug the RJ-11 connector at the back of the TelephonyGateway and plug in a known working phone.
