To power cycle your Internet connection, find the small white or black box that is between the radio on your roof and your computer or router.  This box is your Power over Ethernet adaptor (or PoE) and provides power to the radio on your roof.  The PoE is usually inside the home and close to your computer or router.

To power cycle, remove the power cord from the side of the PoE, leave it unplugged for 15 to 20 seconds, then plug it back in.  You should not need to remove the Ethernet wire from the PoE.  The Ethernet wire has an end that resembles a telephone line.  If you do remove the Ethernet wire, it is important that you connect the wire back into the exact ports from which you removed them.

If you have a router, remove the power cord from the back of the router and the power cord from the PoE simultaneously.  When you return the power to these devices, there is a good chance your Internet will be back to performing the way it should.
