Accessing the

Router using the

3Com Detect

Application

The 3Com Detect application works by automatically locating your

Router, establishing what IP address it is using and then launching your

default web browser to connect directly to it.

The application will only locate your Router if it is on the same subnet as

the PC on which the application is running. It will not be able to locate

your Router if there is another router between your PC and the Router.

Note that the 3Com detect application is

only

designed to run on

Windows operating systems.

Running the 3Com

Detect Application

The CD-ROM that comes with this Router contains, in addition to the

documentation, the 3Com Detect Application.

To use 3Com Detect to connect to the Web interface of your Router, do

the following:

On the computer that is connected to your Router (either directly or on a

network that is on the same subnet), insert the CD-ROM into its CD drive.

If you have autorun enabled, you will be presented with a menu showing

the contents of the CD-ROM. Select the 3Com Detect Application link to

install the utility. Follow the onscreen instructions.

If the auto-run program does not start, you should browse to your

CD-ROM drive, go to the /3Com detect directory and double click on

setup.exe. Follow the prompts that will take you through the installation

process.

Once installed, the 3Com Detect Application can be accessed from the

Windows Start/Programs list.

When the 3Com Detect application starts, you will see the Welcome

Screen, see

Figure 15
