Instant Wireless® Series 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 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 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 dialup 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://192.168.1.1 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. 74 Wireless-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 recommended to use MTU 1492. If you are having some difficulties, perform the following 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 finishing 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 settings 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. 75
