1. Use the Linksys TFTP program to upgrade the firmware. Go to the Linksys website at
http://www.linksys.com and download the TFTP program, which will be listed with the
firmware.
2. Set a static IP address on the PC; refer to "Problem #1, I need to set a static 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
3. Perform the upgrade using the TFTP utility.
If the firmware upgrade failed, the Router will still work using its current firmware.
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.
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.
2. Enter the password, if asked. (The default password is admin.)
3. On the Setup => WAN tab, select the option Keep Alive, and set the Redial Period option at
20 (seconds).
4. Click the Save Settings button.
If the connection is lost again, follow steps E and F to re-establish connection.
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:
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.
2. Enter the password, if asked. (The default password is admin.)
3. Go to Setup => WAN tab.
4. Look for the MTU option, and select Enable. In the Size field, enter 1492.
5. Click the Save Settings button to continue.
