11. Check your computer's operating system to see whether the computer has connectivity (for
example, see Figure 5-1 and refer to the documentation for your operating system). If it
doesn't, try using another computer and NIC attached to the EMTA to connect to the
Internet.
12. Try accessing the Internet with a different browser. If you succeed, the problem exists with
the previous browser you used.

Unable to Access Networked Devices

If you are on a network, but cannot connect to any resources on the network:
1. The Ethernet cable may be worn. Replace the cable if it is worn.
2. The Ethernet cable may not be firmly connected at both ends. Secure the cable at both
ends. Often, just reseating the cable into a connector is all that is required.
3. The port on the EMTA may be bad. Plug the network cable into a different port on the
EMTA.
4. The NIC may be bad or the cable connected to the NIC may be the wrong kind of network
cable (for example, you may be using a straight-through cable when a crossover cable is
required). If you have another NIC available, try using it instead of the one currently used.
5. Ping the IP address of other computers and devices on your network.
6. For Windows operating systems:
– Try connecting to a computer on the network using Start \ Run and enter \\PCname,
where PCname is the name of the computer you want to connect to.
– Add the computer and its IP address to the LMHOSTS file. This is a text file that
resides in the Windows\System32\drivers\etc directory (for Windows2000 or
XP) and has the format IP_Address Computer_Name .
Tip: Browsing is a fairly complicated issue and has a lot of places for failure. If you need to
have resources available, create shortcuts on your desktop instead.

Using the Ping Utility to Troubleshoot

You can use your computer's ping utility to test the path from the computer to the EMTA and
from your computer to the Internet.

Testing the Path from a Computer to the EMTA

You can ping the EMTA to verify that the LAN path from your computer to the EMTA is set
up correctly. To ping the EMTA from a Windows computer:
