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.
STEP 1
To connect to the router, go to the web browser, and enter
http://192.168.1.1
or
the IP address of the router.
STEP 2
Enter the password, if asked (default password is
admin
).
STEP 3
On the
Setup > WAN
menu, select the option
Keep Alive
, and set the Redial
Period option at
20
(seconds).
STEP 4
Click
Save Settings
.
If the connection is lost again, follow steps 1 and 2 to re-establish connection.
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 recommended to
use MTU 1492. If you are having difficulties, perform the following steps:
STEP 1
To connect to the router, go to the web browser, and enter
http://192.168.1.1
or
the IP address of the router.
STEP 2
Enter the password, if asked (the default password is
admin
).
STEP 3
Go to the
Setup > WAN
menu.
STEP 4
Look for the MTU option, and select
Manual
. In the Size field, enter
1492
.
STEP 5
Click
Save Settings
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, and 1300.
