The Connectivity Test 
Menu

You may lose connectivity to a particular server due to the 
Internet and/or the satellite network being heavily loaded or due 
to the server being down. If possible, check connectivity to some 
other server on the Internet to ensure it is not a server specific 
problem. Follow the procedure below for troubleshooting:

Network Operations Center

(NOC) Connectivity

Use the Connectivity Test from the left pane to check 
connectivity to the DIRECWAY NOC.

Note:

You may want to open a second browser window to be able 

to access this help page while conducting the Connectivity Test.

1. Click on 

Connectivity Test

 on the left hand side of the 

User 

Interface

. The screen in Figure 40 appears.

2. Run the test. A message will appear, informing you if the test 

was successful.
If the connectivity test succeeds, try pinging the NOC Router 
Address from the computer. This address can be obtained 
from the 

System Information

 page. See 

System Information

 

on page 45.
If this succeeds, skip to the Internet Connectivity test below.
If this fails, the default gateway is probably not set correctly 
on the computer’s network settings. The default Gateway 
should be the Gateway IP address. Fix this in the computer's 
network settings and repeat the connectivity test.
If the test still fails, power-cycle the DW4020 by unplugging 
the power cord from the wall outlet and plugging it back in. If 
this doesn't fix the problem, call Customer Care.
If the connectivity test fails, check the DW4020 configuration 
via the System Information page.
