The TP-Link Omada ER706W-4G V2 is a high-performance business-grade 4G+ Cat6 VPN gateway with built-in Wi-Fi 6, designed for businesses, branches, and locations where a reliable internet connection is essential even in the event of a primary connection failure. Through two Nano SIM slots, it enables a 4G+ connection with speeds of up to 300 Mb/s, with the second SIM card serving as an automatic backup. In addition to mobile WAN, it also supports Ethernet WAN and enables load balancing and failover between different connections.

The built-in dual-band Wi-Fi 6 AX3000 delivers up to 2 , 402 Mb/s at 5 GHz and 574 Mb/s at 2.4 GHz. Technologies such as HE160, OFDMA, 1024-QAM, MU-MIMO, and Beamforming improve wireless network throughput and efficiency, while Omada Mesh support enables coverage expansion with compatible Omada access points. Up to 16 SSIDs are available, along with support for a guest network and advanced security options.

For business use, the ER706W-4G V2 is equipped with 1 × Gigabit SFP WAN/LAN, 1 × Gigabit WAN, and 4 × Gigabit WAN/LAN ports, enabling up to 6 WAN connections. The device supports a wide range of VPN technologies, including IPsec, WireGuard, OpenVPN, SSL VPN, L2TP, PPTP, and GRE, as well as advanced security features such as DPI, ACL, protection against TCP/UDP/ICMP attacks, ARP Inspection, and IP-MAC Binding.
