Common Problems and Solutions

This section provides possible solutions to problems regarding the installation and operation of the Cable/DSL Router. Read the description below to solve your problems. If you can’t find an answer here, check the Linksys website at www.linksys.com.

1.I Can’t connect to the Cable/DSL Router.

•Verify that the Cable/DSL Router is properly installed, LAN connec- tions are OK, and it is powered ON.

•Make sure that your PC and the Cable/DSL Router are on the same net- work segment. If you are not sure, initiate the DHCP function and let the PC get the IP address automatically.

•Make sure that your PC is using an IP address within the default range of 192.168.1.2 to 192.168.1.254 and thus compatible with the Cable/DSL Router default IP Address of 192.168.1.1.

•The Subnet Mask should be set to 255.255.255.0 to match the Cable/DSL Router. In the Cable/DSL Router, you can check these set- tings by using Control Panel-Network to check the Properties for the TCP/IP protocol.

2.The Diag LED stays lit when it shouldn’t.

•The Diag LED lights up when the device is first powered up. Meantime, the system will boot up itself and check for proper opera- tion. After finishing the checking procedure, the LED turns off to show the system is working fine. If the LED remains lit after this time, the device is not working properly. Try to re-flash the firmware by assign- ing a static IP address to the computer, then upgrade the firmware again. If that doesn’t help, contact your dealer for further information.

3.I can’t browse through the Cable/DSL Router.

•Make sure that both ends of the network cable and power adapter are properly connected and that the status LEDs on the front panel are functioning properly.

•If using Windows 95 or Windows 98, check the TCP/IP setup on the client side. Run "winipcfg" by clicking on the Start button, then select- ing Run. The PC should have an IP address of 192.168.1.xxx ("xxx" is from 2 to 254.) Subnet Mask is 255.255.255.0, the default gateway IP should be the Router’s IP Address, and DNS (in "More".)

•Make sure that the same values are in the Status screen of the Cable/DSL Router’s web-based utility.

4.When I enter a URL or IP address, I get a time out error.

•Make sure that the other PCs work. If they do, ensure that your work- stations IP settings are correct (IP address, Subnet Mask, Default gate- way and DNS)

•If the PCs are configured correctly, but still not working, check the Cable/DSL Router to make sure that it is connected and ON. Once this is the case, check its settings. (If you cannot connect to the Router, check the LAN and power connections.)

•If the Cable/DSL Router is configured correctly, check your Internet connection (the Cable/DSL modem) to see that it is working correctly.

5.I can’t obtain an IP address from my cable or DSL modem.

•Make sure that all of your cabling is properly connected and that all of the Router’s WAN and LAN LEDs are correctly illuminated.

•Power down your cable or DSL modem for a few seconds. Turn it back on. After the modem goes through its self-test, check to see that you now have an IP address.

•Make sure that your cable or DSL modem is DHCP-capable.

•You may have to enter the Router or host name in the Setup page of the Router’s web-based utility. Go to page 16 for more information.

•Your ISP may require Mac Addresses. Check with your ISP. This address can be obtained in the Status screen of the Router’s Web-based Utility.
