This procedure is explained in "Restoring the Default Configuration and Password" on page 7-4. If you are using Internet Explorer, click Refresh to be sure the Java applet is loaded. Make sure that CAPS LOCK is off when entering this information. · · · If the router does not save changes you have made in the web Configuration Interface, check the following: · · When entering configuration settings, be sure to click the APPLY button before moving to another menu or tab, or your changes will be lost. The changes may have occurred, but the web browser may be caching the old configuration, in which case you should clear the browser cache. Troubleshooting a TCP/IP Network Using a Ping Utility Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet to the designated device. Troubleshooting a TCP/IP network is made very easy by using the ping utility in your computer. Testing the Path from Your Computer to a Remote Device To test the path from your computer to a remote device, from the Windows run menu, type: PING -n 10 <IP address> where <IP address> is the IP address of a remote device such as your ISP's DNS server. If the path is functioning correctly, replies as in the previous section are displayed. If you do not receive replies: Troubleshooting February 2005 (202-10034-03) 7-3 Reference Manual for the 54 Mbps Wireless Travel Router WGR101 -- Check that your computer has the IP address of your router listed as the default gateway. If the IP configuration of your computer is assigned by DHCP, this information will not be visible in your computer's Network Control Panel. Verify that the IP address of the router is listed as the default gateway as described in "Verifying TCP/IP Properties" on page C-6. -- Check to see that the network address of your computer (the portion of the IP address specified by the netmask) is different from the network address of the remote device. -- Your ISP could be rejecting the Ethernet MAC addresses of all but one of your computers. Many broadband ISPs restrict access by only allowing traffic from the MAC address of your broadband modem, but some ISPs additionally restrict access to the MAC address of a single computer connected to that modem. If this is the case, you must configure your router to "clone" or "spoof" the MAC address from the authorized computer. Refer to "Configuring Basic Settings Options" on page 6-3. Restoring the Default Configuration and Password This section explains how to restore the factory default configuration settings, changing the router's administration password to password and the IP address to 192. 168. 0. 1. You can erase the current configuration and restore factory defaults in two ways: · · Use the Erase function of the router (see "Erasing the Configuration" on page 5-8). Use this method for cases when the administration password or IP address is not known. To restore the factory default configuration settings without knowing the administration password or IP address, you must use the Default Reset button on the rear panel of the router. 1. 2. Press and hold the Default Reset button until the power light blinks on (about 10 seconds). If the wireless travel router fails to restart or the power light continues to blink or turns solid amber, the unit may be defective. If the error persists, you might have a hardware problem and should contact technical support. 7-4 February 2005 (202-10034-03) Troubleshooting Appendix A Technical Specifications This appendix provides technical specifications for the 54 Mbps Wireless Travel Router WGR101.

[. . . ] In this case, a part of the host address is reserved to identify the particular subnet. The full address is: 10010110. 11010111. 00010001. 00001001 The Class B network part is: 10010110. 11010111 and the host address is 00010001. 00001001 If this network is divided into 14 subnets, however, then the first 4 bits of the host address (0001) are reserved for identifying the subnet. The subnet mask is the network address plus the bits reserved for identifying the subnetwork. (By convention, the bits for the network address are all set to 1, though it would also work if the bits were set exactly as in the network address. ) In this case, therefore, the subnet mask would be 11111111. 11111111. 11110000. 00000000.
