Common Problems and Solutions
Wired Broadband Router
13. My DSL service’s PPPoE is always disconnecting.
PPPoE is not actually a dedicated or always-on connection. The DSL ISP can disconnect the service after a
period of inactivity, just like a normal phone dial-up connection to the Internet. There is a setup option to
“keep alive” the connection. This may not always work, so you may need to re-establish connection
periodically.
A. To connect to the Router, go to the web browser, and enter
http://192.168.15.1
or the IP address of the
Router.
B. Enter the password, if asked. (The default password is admin.)
C. On the
Basic Setup
tab, select the option
Keep Alive
, and set the
Redial Period
option at
20
(seconds).
D. Click the
Save Settings
button.
E. Click the
Status
tab, and click the
Connect
button.
F. You may see the login status display as Connecting. Press the
F5
key to refresh the screen, until you see
the login status display as Connected.
If the connection is lost again, follow steps E and F to re-establish connection.
14. I can't access my email, web, or VPN, or I am getting corrupted data from the Internet.
The Maximum Transmission Unit (MTU) setting may need to be adjusted. By default, the MTU is set at 1500.
For most DSL users, it is strongly recommended to use MTU 1492. If you are having some difficulties,
perform the following steps:
A. Open the web browser, and enter
http://192.168.15.1
or the IP address of the Router.
B. Enter the password, if asked. (The default password is
admin
.)
C. On the
Basic Setup
tab, look for the MTU option, and select
Manual
. In the
Size
field, enter 1492.
D. Click the
Save Settings
button to continue.
If your difficulties continue, change the Size to different values. Try this list of values, one value at a time, in
this order, until your problem is solved:
1462
1400
1362
1300
15. I need to use port triggering.
Port triggering looks at the outgoing port services used and will trigger the Router to open a specific port,
depending on which port an Internet application uses. Follow these steps:
A. To connect to the Router, go to the web browser, and enter
http://192.168.15.1
or the IP address of the
Router.
