Identify what device(s) your computer is connected to.

            Some examples of common networking devices include:

Figure A.


Figure B.

 Wall Jack (Power Injector)

Figure C.



Verify that all networking devices are powered on.

            Most networking devices have status lights.

a.                   Routers and Switches Figures A and C.

                        Status and activity lights are found on the front of these devices. If there are lights on the device, it is powered on.

b.                 Wall jack (power injector) Figure B

        I.        There are two lights on the device. One indicates power to the injector, and one indicated power to the radio antennae. Both should be solid at all times.

                       II.        If one or both of these lights are not lit, follow the steps below.



1)    Verify that the black power adapter is plugged in.


2)    Verify that the Cable connected to your computer (or router) is connected to the “NET” port.


3)    Verify that the cable coming from the wall is connected to the “ODU” or “Radio” port on the injector.

After verifying that all of the connections are correct, and one or both of the lights are not lit, please call Coastinet tech support at (951) 471-1649

If all devices seem to be powered on, view the “Common Network Wiring” section

Reboot your devices.
Follow the steps below to reboot the above devices.
                        a.   Unplug the power cable to the device as illustrated below.

                        b.   Leave the power cables out for 30 seconds.
                        c.   Reinsert power cables to their respective devices.
                        d.   Wait 30 seconds to 1 minute.
                        e.   Try your connection again.

                                                          vii.      If numbers in the “IP ADDRESS” field are 192.168.x.x or 69.45.x.x, you
                     have a valid address.

                                                        viii.      If numbers are or 169.x.x.x, your computer has no valid IP

Reboot Computer

Sometimes, applications and processes will cause your computer to become unresponsive. Shutting your computer down and powering it back up will often resolve small problems such as these.

Wireless Networks

If you are connected to the Internet through a wireless router, it is always a good idea to first test your line with a computer that is directly connected to your router via a cable. With the recent popularity of wireless devices, radio interference has increasingly become a problem. A sudden loss of connectivity can simply mean that a new source of interference has “popped up.”

By connecting your computer directly to your router through a cable, you will be able to determine whether it is an internal wireless issue, or another problem.
