How Do I Set Up My C4R-800 Cat 18 Modem?

Updated: Apr 9


Your C4R-800 Cat 18 modem comes with the following hardware:

  • 2 Antennas

  • 1 Power supply

  • 1 Ethernet cable


After unpacking the device, attach the supplied antennas, and plug the modem in with the provided power supply. Generally, for the strongest signal strength we recommend placing the device near a window.


The device may take several moments to fully start up. Once the Power light, net light, sim light, 2ghz light, 5ghz light, and the 4G light are all illuminated the device is ready to connect to wirelessly.


There will be two wireless networks you are able to connect to:

Net_All_Over_2.4G_xxx & Net_All_Over_5G_xxx


Use the Net_All_Over_2.4G-xxx for devices that are far away from the modem or that do not support 5GHZ connections and use the Net_All_Over_5G-xxx for devices that are close to the modem.


The default password for both networks is: 1234567890


If you find the device is going slowly or having trouble finding a stable connection, we recommend moving it around your house until you find the place with the strongest signal. The signal lights on the modem ARE NOT an indicator of signal strength.

If you cannot find an area with strong signal strength you may need an external antenna or cell booster. You can call our support line (888-425-3656) to discuss which product would work best for your needs.


Net All Over was founded by one of the innovators of Wireless Internet (Wi-Fi) service, having designed one of the first outdoor wireless Internet networks in the U.S. in 1996. Our goal is to provide high-speed Internet service to rural or low-service areas that either have no competitive alternative – OR – have no high-speed choice at all.
