Save your configuration and restart 21Figure 6: Rear panel of the Q2201 routerYou have made the proper WAN and LAN connections if the corresponding front-panel STAT LEDs and the rear-panel ACT LEDs are green. The front panel ModemLED is green if the router is equipped with the optional modem and it is configuredfor use. If these LEDs are not green, the problem is most likely one of the following:• The cable is plugged into the wrong connector or wall jack• The cable is not completely plugged in—reconnect both ends of the cable• The cable is damaged or defective, or the wrong type of cable was used—try another cable appropriate for the connection• The interface was configured incorrectly—compare your setup with theconfiguration worksheet; contact your network administrator or serviceprovider to verify the worksheet information if no mistakes are found• The service is not available—contact your service provider for resolutionStep 8: Save your configuration and restartWhen you make changes to the default configuration, the router stores thosechanges in RAM. Your changes will be lost if you lose power or restart the systemwithout first saving those changes to non-volatile memory.a Take a few minutes now to save the changes you have made so far andrestart the router to refresh IP connections. Go to the Configure > System >Restart page to save your changes and restart the router.b Once you have restarted the router, restart each attached PC on the LAN torelease and renew the DHCP configurations.Note that if you plan to explore advanced features of the router, you may decide totest more complicated configuration changes without saving them, so that you cantest those changes and undo any mistakes with a system restart.Step 9: Test access to the WANVerify that the WAN interface is functional by running a ping test from the router toa known host on the WAN, such as the default gateway.To do this, go to the Monitor > Traffic > Ping page, and enter the name or IP addressof the remote host. If successful, you will see detailed information about the pingthat includes the line “1 transmitted, 1 received, 0 lost.” An unsuccessful ping testwill result in a “Request timed out” message.0(7+(51(7/$1 7:$1 02'(0 56/,1. /,1. /,1. /,1.%7 %7 %7 %7 $&7 $&7$/0$/03257 3257 3257 32575(6(732:(59'&4 7!. $# 0OWER ,!. -ODEM 23
