Dual-Band Wireless A/G Broadband Router
15. I can’t access my e-mail, 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
http://192.168.1.1
or the
IP address
of the Router.
B. Enter the password, if asked. (The default password is
admin
.)
C. Click the
System
tab.
D. Look for the MTU option, and select
Manual
. In the
Size
field, enter
1492
.
E. Click the
Apply
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
16. The Diag LED stays lit continuously.
• The Diag LED lights up when the device is first powered up. Meantime,
the system will boot up itself and check for proper operation. After fin-
ishing the checking procedure, the LED turns off to show that the system
is working fine. If the LED remains lit after this time, the device is not
working properly. Try to flash the firmware by assigning a static IP
address to the computer, and then upgrade the firmware. Try using the
following settings, IP Address: 192.168.1.50 and Subnet Mask:
255.255.255.0.
17. When I enter a URL or IP address, I get a time-out error or am prompted to retry.
• Check if other PCs work. If they do, ensure that your workstation’s IP set-
tings are correct (IP Address, Subnet Mask, Default Gateway, and DNS).
Restart the computer that is having a problem.
• If the PCs are configured correctly, but still not working, check the
Router. Ensure that it is connected and powered on. Connect to it and
check its settings. (If you cannot connect to it, check the LAN and power
connections.)
• If the Router is configured correctly, check your Internet connection
(DSL/cable modem, etc.) to see if it is working correctly. You can remove
the Router to verify a direct connection.

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
System
tab.
14. 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 con-
nection. This may not always work, so you may need to re-establish connec-
tion periodically.
A. To connect to the Router, go to the web browser, and enter
http://192.168.1.1
or the
IP address
of the Router.
B. Enter the
password
, if asked. (The default password is
admin
.)
C. On the
Setup
screen, 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 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 to continue.
If the connection is lost again, follow steps E to G to re-establish connection.
