63interference coming from. It will also show the frequencies and the level of signaldetected.Avoiding InterferenceWhen a source of interference is identified and when the level and frequencies areknown, the next step is to avoid the interference. Some of the following actions can beperformed: Switch the RF channel away from the interference source. Change the polarization of the antenna; try to change to a polarization differentfrom the incoming interference. A small beam antenna may help (such as a grid or dish antenna). Aligning theantenna properly will reduce the effects of the interference. This solution won’thelp when the source of interference is extremely close the remote site.Before checking for interference, ensure all of your hardware is working properly andyour configurations are correct. The path analysis, cabling and antennas should bechecked as well.9-2 Connection IssuesThis section describes several common problems you might have while setting theradios.Radio Does Not BootWhen the radio does not boot, use the following steps to check your system:1. Ensure that the power supply is properly working and correctly connected.2. Ensure that all cables are workable and connected correctly.3. Check the power source.Cannot use the Web InterfaceIf the radio boots properly, but remains inaccessible via the web interface:1. Open a command prompt window and enter ping (for example:ping 192.168.1.1). If there is no response from the radio, make sure that youthe IP address is correct. If there is response, the Ethernet connection is workingproperly, do the next step.
