The Power LED flashes 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 stays solid to show that the
system is working fine. If the LED keeps flashing after this time, the device is not working properly.
• If this occurs after attempting a firmware upgrade, use the TFTP program, which was downloaded along
with the firmware.
• Visit the Linksys support website, www.linksys.com/support, and download the Router's firmware and
TFTP program. Open the pdf that was downloaded along with the firmware and TFTP program, and then
follow the pdf's instructions.
• Set a static IP address on the computer; refer to "Problem #2: I need to set a static IP address on a PC".
Use the following settings for the computer you are using:
IP Address: 192.168.1.50
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.
• Manually configure the TCP/IP settings with a DNS address provided by your ISP.
• Make sure that your browser is set to connect directly and that any dial-up is disabled. For Internet
Explorer, click Tools, Internet Options, and then the Connection tab. Make sure that Internet Explorer is
set to Never dial a connection. For Netscape Navigator, click Edit, Preferences, Advanced, and Proxy.
Make sure that Netscape Navigator is set to Direct connection to the Internet.
