By default, the DLOS8N is set to use the WAN port to connect to an upstream network. When you connect the DLOS8N’s WAN port to an upstream router, DLOS8N will get an IP address from the router and have Internet access via the upstream router. The network status can be checked in the (% style="color:#4f81bd" %)**home page**:

It is possible but the distance will be very short, you can select US915 frequency band in 868Mhz version hardware. It will work but you will see the performance is greatly decreased because the 868Mhz version has an RF filter for band 863~~870Mhz, all other frequencies will have high attenuation.
