Your Network Upgrade: The EdgeRouter 4 in Detail
If your Network needs to be more than just standard, the Ubiquiti EdgeRouter 4 is the answer. This High-Performance Gigabit Router was developed for maximum stability and highest data throughput. It is the ideal central unit for prosumers, small businesses, and all tech enthusiasts who want full control over their Network. Thanks to its powerful hardware and the advanced EdgeOS operating system, you can effortlessly implement complex tasks such as VLAN segmentation, demanding firewall rules, and Quality of Service (QoS) without compromising the performance of your Gigabit connection.
Maximum Control for Professionals: CLI, SFP, and EdgeOS
The ER-4 is more than just a simple Router. While the graphical user interface allows for a quick start, the device unfolds its full potential via the command-line interface (CLI). Here you can perform a detailed EdgeRouter 4 configuration for multiple VLANs or set up dynamic routing protocols like OSPF and BGP. The SFP Port, compatible with SFP / SFP\+ Modules, gives you the freedom to establish a direct fiber optic connection, making the ER-4 the perfect choice for modern FTTH connections. Combined with the option for remote management via UISP (formerly UNMS), you have your Network always and everywhere under control.
Reliability You Can Count On
In a world where a stable internet connection is crucial, the EdgeRouter 4 sets standards. Its fanless design not only ensures absolute silence but also minimizes the number of moving parts, drastically reducing the probability of failure. Users report months or even years of uptime without a single reboot. If you are looking for a 'set-it-and-forget-it' solution that simply works, this Router for small businesses without WiFi is the absolutely right choice. Simply combine it with separate WiFi Access Points and build a modular, extremely stable Network.

Frequently Asked Questions (FAQ)
Is the Ubiquiti EdgeRouter 4 suitable for beginners?
No, the EdgeRouter 4 is primarily aimed at technically skilled users and Network administrators. While a basic setup is possible via a wizard, advanced functions such as VLANs, specific firewall rules, or VPN configurations require in-depth Network knowledge.
Does the EdgeRouter 4 have WiFi?
No, the ER-4 is a purely wired router and does not have integrated WiFi functionality. To build a WiFi Network, it must be connected to one or more separate WiFi Access Points.
What is the difference between the EdgeRouter 4 and the UniFi Security Gateway (USG)?
The main difference lies in management. The EdgeRouter 4 is configured as a standalone device via its web interface or CLI. The UniFi Security Gateway (USG) is centrally managed via the UniFi Controller, which simplifies integration into a pure UniFi Network. Technically, the EdgeRouter 4 often offers higher routing performance.
Can the EdgeRouter 4 fully utilize a Gigabit internet connection?
Yes, thanks to its 4-core CPU and hardware offloading, the EdgeRouter 4 can fully utilize a Gigabit internet connection (1 Gbit/s) without speed degradation. Its line rate is up to 4 Gbps.
What does hardware offloading mean for the ER-4?
Hardware offloading means that the Router uses special hardware components to process data traffic instead of burdening the main CPU. This significantly increases data throughput and must be explicitly enabled for maximum performance.
What is the VPN performance of the EdgeRouter 4?
The IPsec-VPN performance benefits from hardware acceleration and can reach several hundred Mbit/s. OpenVPN performance is significantly lower as it is not hardware-accelerated and runs purely on the CPU, which is typical for many Routers.
