This article covers Ubiquiti Networks Edgerouter LITE 3Port Router ERLite-3.

Overview

The Ubiquiti EdgeRouter Lite ERLite-3 is a compact wired router that packs serious routing performance into a small, fanless chassis. Powered by a dual-core 500 MHz MIPS64 processor with hardware acceleration, it can handle up to 1 million packets per second — enough for most home and small office networks. With three Gigabit Ethernet ports and the feature-rich EdgeOS operating system, this router offers enterprise-level capabilities at a consumer-friendly price. EdgeOS provides both a web-based GUI and a full CLI for configuration, supporting dynamic routing protocols like OSPF, BGP, and RIP. VPN functionality is extensive, covering IPsec site-to-site and remote access, OpenVPN, PPTP, and L2TP. Security features include zone-based firewalls, ACL-based filtering, and NAT. The ERLite-3 has been a staple in the prosumer networking space since its 2013 launch, and firmware updates continue to be released, keeping it relevant for basic routing tasks.

Connectivity & Compatibility

Three Gigabit Ethernet ports (10/100/1000) — WAN/LAN assignment is software-configurable, allowing flexible network topology. One RJ45 serial console port for CLI access during initial setup or troubleshooting. Power input: 12 VDC, 1A (adapter included); supports 9–24 VDC range for alternative DC power sources. Compatible with any standard Ethernet device: PCs, servers, switches, access points, and more. * Supports PPPoE, DHCP client, and static IP for broadband internet connectivity.

Product Info

The EdgeRouter Lite ERLite-3 was released in 2013 and remains available through Ubiquiti's official channels and major retailers like . Pricing typically falls in the ¥27,000–¥30,000 range. The package includes the router, an AC adapter, and a quick-start guide — no Ethernet cables are included. Warranty is the standard one year from the manufacturer (may vary by seller). Market positioning is entry-to-mid-range. It sits between consumer-grade all-in-one routers and expensive enterprise hardware, offering genuine routing features at a fraction of the cost. The long-term firmware support is a standout advantage in this price bracket.

Best Use Cases

Enthusiasts building a serious home network: If you've outgrown typical consumer routers and need VLANs, dynamic routing, or granular QoS, the ERLite-3 delivers. Its CLI offers Cisco-like control once you learn the syntax. However, beginners will face a steep learning curve — some networking knowledge is essential. Small office or creative workspace: For environments requiring stable wired connections across multiple PCs, NAS devices, and printers, this router provides reliable throughput. Built-in VPN support enables secure remote access for teleworkers. Note that you'll need a separate access point for Wi-Fi. * Budget-friendly enterprise routing practice: The ERLite-3 is widely available new and on the secondary market at low cost. It's an excellent learning tool for BGP, OSPF, and firewall concepts, making it popular among CCNA students. But if you need Wi-Fi 6 or 10GbE, look elsewhere.

Things to Consider

This is a wired-only router — no built-in Wi-Fi. You must add an access point or wireless router separately for wireless connectivity. The MIPS64 processor, while efficient, is not as powerful as modern ARM or x86 alternatives. Its 1 Mpps routing capacity may bottleneck a full 1 Gbps connection under heavy load. Firmware updates are still provided, but some legacy features in EdgeOS 2.x have been deprecated. Always update to the latest firmware before deployment. Advanced configuration requires CLI proficiency. The web GUI covers basic NAT and DHCP, but VLANs, VPNs, and routing protocols demand command-line skills. This product is best suited for users with networking experience or a willingness to learn. ## FAQ
Q: Does this router support Wi-Fi? A: No, the EdgeRouter Lite ERLite-3 is a wired-only router. You'll need a separate access point or wireless router for Wi-Fi connectivity. Q: Can it handle a full gigabit internet connection? A: Its maximum routing throughput is around 1 million packets per second, which translates to roughly 800–900 Mbps under ideal conditions. For consistent full 1 Gbps performance, consider a higher-end model like the EdgeRouter 4. Q: Is it difficult to set up? A: Basic NAT and DHCP can be configured via the web GUI, but advanced features (VLANs, dynamic routing, VPNs) require CLI knowledge. It's designed for users with networking experience or those eager to learn.
