The EIPR routers have a 10/100Mbps Ethernet WAN port and a built-in 4-port LAN switch. By installing the appropriate USB adapter, a Wi-Fi LAN connection can be made with either EIPR model, or in the case of a cellular adapter with EIPR-V, a WAN connection to a cellular provider can be made. The EIPR-V has a resident OpenVPN® client for accessing a virtual private network server—thereby creating a VPN tunnel with higher security.
