15. 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 recom-
mended to use MTU 1492.
If you are having some difficulties, perform the fol-
lowing steps:
A. To connect to the Router, go to the web browser, and enter
or the
IP address
of the Router.
B.
Enter the password, if asked. (The default password is
admin
.)
C.
Click the
Advanced => Filter
tab.
D.
Look for the MTU option, and select
Enable
. In the Size field, enter
1492
.
E.
Click the
Apply
button.
If your difficulties continue, change the
Size
to different values. Try one value
at a time, in this order, until your problem is solved:
1462
1400
1362
1300

or the

Enter the password, if asked. (The default password is

name
you want to use for the Application Name.

Triggered Port Range
. Check with your Internet application
provider for more information on which outgoing port services it is using.

provider for more information on which incoming port services are

13. The firmware upgrade failed and/or
the Diag LED is flashing.
The upgrade could have failed for a number of reasons.
Follow these steps to
upgrade the firmware and/or make the Diag LED stop flashing:
A.
If the firmware upgrade failed, use the
TFTP
program (it was downloaded
along with the firmware). Open the pdf that was downloaded along with the
firmware and TFTP program, and follow the pdf’s instructions.
B.
Set a
static IP address
on the PC; refer to “Problem #1, I need to set a stat-
ic IP address.” Use the following IP address settings for the computer you
are using:
IP Address: 192.168.1.50
Subnet Mask: 255.255.255.0
Gateway: 192.168.1.1
C.
Perform the upgrade using the TFTP program or the Router’s web-based
utility through its Help tab.
14. I am using PPPoE with my DSL service, but it is always disconnecting.
PPPoE is not a dedicated or always-on connection.
The DSL ISP can discon-
nect the service after a period of inactivity, just like a normal phone dial-up
connection to the Internet.
Using the setup option “keep alive” will help keep
the connection.
This may not always work, so you may need to re-establish the
connection periodically.
A. To connect to the Router, go to the web browser, and enter
or the
IP address
of the Router.
B.
Enter the
password
, if asked. (The default password is
admin
.)
C.
In the Setup tab, select the option
Keep Alive
, and set the
Redial Period
option at
20
(seconds).
D.
Click the
Apply
button.
E.
Click the
Status
tab, and then 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
.
G.
Click the
Apply
button.
If the connection is lost again, follow steps E to G to re-establish the connec-
tion.
