Introduction
TM-G5240 Wireless Router
Congratulations on your purchase of the T-Mobile TM-G5240 wireless router (also
referred to as TM-G5240).
The TM-G5240 supports high-speed wireless networking at home, at work, and in public
places. The TM-G5240 wireless router uses the new 802.11g standard. The IEEE
802.11g standard is an extension of the 802.11b standard. It increases the data rate up
to 54 Mbps within the 2.4GHz band, utilizing OFDM technology.
In addition to offering fast data transfer speeds, the TM-G5240 has the newest, strongest,
and most advanced security features available today (WPA and 802.1x):
•
WPA: Wi-Fi Protected Access authorizes and identifies users based on a secret
key that changes automatically at a regular interval. WPA uses TKIP (Temporal
Key Integrity Protocol) to change the temporal key every 10,000 packets (a packet
is a kind of message transmitted over a network.) This insures much greater
security than the standard WEP security. By contrast, the older WEP encryption
required the keys to be changed manually.
•
Authentication: Authentication is a first line of defense against intrusion. In the
authentication process, the server verifies the identity of the client attempting to
connect to the network. Unfamiliar clients would be denied access.
What is unique about the TM-G5240
The TM-G5240 is unique in that it has been optimized to work with a compatible T-Mobile
phone so that you can use your phone for calling via your Wi-Fi network or the T-Mobile
GSM network.

WPA (Wi Fi Protected Access) authorizes and identifies users based on a secret
key that changes automatically at a regular interval, for example:
o TKIP (Temporal Key Integrity Protocol), in conjunction with a RADIUS
server, changes the temporal key every 10,000 packets, ensuring greater
security.
o Pre Shared Key mode means that the home user, without a RADIUS
server, can connect securely via a pre-shared key, vastly improving the
safety of communications on the network.

Getting Started
What you need before installing the TM-G5240
Before you install and use the TM-G5240, you must have:
•
Broadband Internet access
(a cable or DSL-subscriber line into your home or office)
NOTE: Consult with your Cable or DSL provider for proper installation of the modem.
•
Computer with Windows, Macintosh*, or Linux-based operating system with an
installed Ethernet adapter.
*The CD wizard is not compatible with Mac/Apple computers (See page 10).
•
Internet Explorer Version 6.0 or Netscape Navigator Version 6.0 or above
Other installation considerations
The TM-G5240 lets you access your network, using a wireless connection, from virtually
anywhere within its operating range. 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:
•
Each wall or ceiling can reduce your TM-G5240’s range from 3-90 feet (1-30
meters). Position the TM-G5240 so that the number of walls or ceilings is
minimized.
•
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.
8
T-Mobile TM-G5240 Wireless Router User Manual
Version 0.7 041807
•
Building materials can impede the wireless signal - a solid metal door or aluminum
studs may have a negative effect on range. Try to position wireless devices and
computers with wireless adapters so that the signal passes through drywall or
open doorways and not other materials.
•
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or
appliances that generate extreme radio frequency noise (example, microwave).

Troubleshooting
Introduction
This section provides solutions to problems that can occur during the installation and
operation of the TM-G5240.
Note: It is recommended that you use an Ethernet connection to configure the TM-G5240
wireless router.
I can’t connect to the Internet
Check the lights for the TM-G5240.
• Power light – solid green
• Internet light – blinking green
• Port light (any port 1-4) – blinking green for data activity or solid green for no activity
but has good connection
Confirm that all cables are connected correctly and securely.
• The modem is connected to your high speed internet connection.
• The modem is connected to the Internet port of the TM-G5240.
• The computer is connected to one of the numbered ports (1-4) on the TM-G5240.
• The TM-G5240’s power adapter is connected to an electrical outlet.
Power off all devices (unplug if needed) and power on each device in the following order:
• Cable or DSL modem
• TM-G5240
• Computer
If you have a static IP address, make sure your computer’s Internet settings are set to
DHCP for the initial setup. See How do I assign static IP address section in this manual.

Version 0.7 041807
When running the CD Install Wizard I can’t get past the cabling
steps
This means the computer you are running the CD with can not communicate with the
wireless router. Try the following:
1. Check that your cables are correct based on the images in the CD Wizard and then
see the text in the troubleshooting issue I can’t connect to the internet.
2. Re-run the CD, ensure all lights are on for the router before moving past step 9.
I’m prompted for a username and password when opening my
Web browser
It is most likely that your DSL (PPPoE) software installed on your computer is requesting
this information. Since the TM-G5240 will now authenticate and connect you to your DSL
service, you must disable or uninstall any PPPoE software from your computer. PPPoE
software will not work behind your TM-G5240. Please contact your Internet Service
Provider for assistance.
I want to use a broadband modem with a USB connection
The TM-G5240 only works with a modem with an Ethernet connection. Most modems will
offer both USB and Ethernet. Disconnect the USB connection before starting the
installation procedure. If your modem has only a USB connection, contact your Internet
Service Provider for assistance.
The CD will not run when I insert it into the CD-ROM drive
The autorun function of your CD drive may be disabled. To manually launch the Setup
Wizard:
1. On your computer, click Start > Run.
2. At the Run box, type d:/Installation_Wizard.exe (d is the drive letter for your CDROM drive).
3. Click OK to start the Setup Wizard.

I can’t wirelessly connect to the TM-G5240
•
Verify your wireless settings on your computer. Make sure the SSID and security
settings are the same as the TM-G5240.
•
Change the channel on the TM-G5240 to reduce interference. For best results, use
channels 1, 6, or 11.
•
Keep the TM-G5240 at least three feet away from electrical devices that generate
radio frequency noise (example, cordless phones, microwaves, computer monitors,
electric motors, UPS units).
Place the TM-G5240 in the most central location of the house. Do not place the TM-G5240 in a
closet, cabinet, or in the garage. See Other Installation Considerations section in this manual for
further information on the best placement of your TM-G5240.
My wireless connection keeps dropping
•
Try a different antenna orientation for the TM-G5240. Try to keep the antenna at least six
inches away from the wall or other objects.
•
If you are using 2.4GHz cordless phones, X-10 equipment or other home security
systems, ceiling fans, and lights, your wireless connection will degrade dramatically or
drop altogether. Try changing the channel on your TM-G5240 and on all the devices in
your network to avoid interference.
•
Keep your product away (at least 3-6 feet) from electrical devices that generate RF noise,
like microwaves, monitors, electric motors, and so on.
Telephone cable or coaxial cable will not work with TM-G5240
The TM-G5240 does not function as a modem. Dial-up Internet access will not work with
the TM-G5240. You must have a broadband modem supported by your Internet provider.
If you have broadband Internet and a Windows PC, run the CD included with the TMG5240.
