Cudy 4G Cat 4 AC1200 Wi-Fi 5 Router, 4 Fast Ethernet Ports,

The Cudy 4G Cat 4 AC1200 Wi-Fi 5 Router provides wireless internet connectivity for homes, small offices, and retail kiosks by utilizing cellular data alongside traditional connections. It gives users without standard broadband options a straightforward path online by inserting a nano SIM card, making it suitable for rural areas and locations needing backup connectivity.

For local wireless coverage, the router broadcasts dual-band Wi-Fi 5, supplying up to 867 Mbps on 5 GHz and 300 Mbps on 2.4 GHz. It incorporates beamforming technology to support activities like video conferencing, gaming, and 4K streaming. For wired gear, four Fast Ethernet ports allow you to link desktop PCs, IP cameras, and smart home equipment directly, while external antennas help capture reliable cellular reception.

Network reliability and security are central to the design. Automatic WAN failover detects when your primary wired line disconnects and switches over to 4G LTE to keep vital devices online. The device also integrates WireGuard, OpenVPN, and IPsec VPN client and server functionality right out of the box, letting you manage encrypted remote access without separate hardware.

One clear limitation is the network hardware class: LTE Cat 4 delivers download speeds up to 150 Mbps, and the wired ports are Fast Ethernet, which means you will not reach gigabit speeds. Shoppers should also keep in mind that cellular speeds rely heavily on available carrier signal.

Verdict: This compact router is a smart pick for anyone needing a dependable backup connection or rural internet via SIM card. It offers a solid mix of dual-band Wi-Fi, built-in VPN protocols, and automatic failover for small setups.

A great fit if you:

• Need a reliable cellular backup connection with automatic WAN failover for a small office or kiosk.
• Live in a rural area without access to standard cable or DSL internet.
• Want built-in VPN client or server features like WireGuard, OpenVPN, or IPsec without extra equipment.
• Need wired Ethernet ports to connect local hardware like desktop PCs and IP cameras.

Consider something else if you:

• Require Gigabit wired port speeds rather than Fast Ethernet.
• Need LTE cellular speeds beyond the Cat 4 standard of 150 Mbps download.
