Ubiquiti Networks Edgerouter 4 (ER-4)

Product Information

WARNING: FAILURE TO PROVIDE PROPER VENTILATION MAY CAUSE FIRE HAZARD. KEEP AT LEAST 20 MM OF CLEARANCE NEXT TO THE VENTILATION HOLES FOR ADEQUATE AIRFLOW. It is highly recommend to upgrade to the most recent firmware release before following this guide. See the How to Upgrade the EdgeOS Firmware article for more information. NOTE:It is recommended to configure the ISP supplied modem/router in bridge mode. This setting will forward the public IP from the ISP modem/router to the EdgeRouter. Now, let’s talk connectivity. With a diverse range of ports, the EdgeRouter 4 is all set to cater to your multiple devices. Its stable connection ensures that it doesn’t fumble even when you’ve got a house full of gadgets all hooked up. While it may not give those best long-range routers a run for their money in terms of sheer distance, it’s perfect for most standard spaces. Setting Up, Simplified For now home with 500/500 or below, I can't see a reason why ER-X won't fit and perform well. ubnt has promised to looking into and enabling the extra 1Gbps pipe. If that really happens, ER-X will still be a killer deal for home up to 1000/1000.

EDAC DEVICE1: Giving out device to module octeon-l2c controller octeon_l2c_err: DEV octeon_l2c_edac (POLLED) However the reason for my 4 star rating is the web interface can be rather clunky at times and there are some features that can only be configured via SSH or the serial console port. For example, to change both the router's DNS server a... view more For a professional router it is easy to setup, even has a series of wizards to take you setup of your WAN and LAN connections with highly configurable ports. Offloading is used to execute functions of the router using the hardware directly, instead of a process of software functions. The benefit of offloading in EdgeOS is increased performance and throughput by notdepending on the CPU for forwarding decisions. A Zone-Based Firewall assigns each interface to a specific zone. The firewall zones will be used to define what traffic is allowed to flow between the interfaces. The traffic that originates in the EdgeRouter itself will also be assigned to a zone: the local zone. DHCPv6 If your ISP supports IPv6 using DHCPv6-PD, you will need to assign the supplied Prefix length given from the ISP, enable the default IPv6 firewall, and define the LAN interfaces that will need IPv6 connectivity.As of the v1.9.1 EdgeOS firmware release, all EdgeRouter models support some type of hardware offloading. Please see our Hardware Offloading article for more information. The tables below summarizes the algorithms that can be offloaded on each platform. MediaTek-Based Devices Kernel command line: root=/dev/mmcblk0p2 rootdelay=10 rw rootsqimg=squashfs.img rootsqwdir=w mtdparts=spi32766.0:2048k(boot0),2048k(boot1),64k(eeprom) console= ttyS0,115200 rootwait rootflags=data=journal

There is nothing off the shelf at this price that is this complete, well supported with great online documentation(important), and solid firmware support. Other differences between the routers are the amount of interfaces (including SFP/SFP+ slots) and the available resources. The ER-4 for example, has a 4-core 1GHz CPU with 1GB of available RAM, whereas the ER-X has a 2-core 880 MHz CPU with 256MB of available RAM.No product lives in isolation, and the EdgeRouter 4 certainly has its fair share of competitors. The tech market is flooded with devices, some even vying for the spot of best budget router or specialized features like the best mobile hotspot for gaming. But competition is what keeps brands on their toes, ensuring that they consistently deliver their best. To Buy or Not To Buy?

What is Hardware Offloading?

Linux version 5.4.188 (builder@buildhost) (gcc version 8.4.0 (OpenWrt GCC 8.4.0 r16554-1d4dea6d4f)) #0 SMP Sat Apr 16 12:59:34 2022 For example, ubnt upgrades Linux kernel in ER-X to align with the higher end models recently. Also pushed MediaTek to release a SDK with 4.x kernel. So by firmware v2 timeframe, all EdgeRouters will be upgraded and aligned on Linux 4.x. Such as these actions are essential upgrades over a product's multiyear lifetime. We recommend that you protect your networks from harmful outdoor environments and destructive ESD events with industrial-grade, shielded Ethernet cable from Ubiquiti.

Yes, the Ubiquiti EdgeRouter 4 offers an intuitive, user-friendly interface that guides users through the setup process, making it straightforward and hassle-free.

Hardware Offloading and Traffic Analysis (Deep Packet Inspection)

bridge: filtering via arp/ip/ip6tables is no longer available by default. Update your scripts to load br_netfilter if you need this. The Flow Flushingfeatureis enabled by default, which means that the flows in the offloading engine are flushed when a routing table change is detected. This means that any routing updates are processed instantly, but it also means that CPU resources are used to process these changes. In environments where the routing table is constantly updated, it can be advisable to disable the Flow Flushing feature which will decrease the load on the CPU and increase the performance. Starting from the v1.10.3 release, the following commands are available to disable the feature: set system offload ipv4 disable-flow-flushing-upon-fib-changes The Ubiquiti EdgeRouter 4 is a versatile router capable of handling multiple tasks efficiently. Its high-speed performance and robust connectivity make it an ideal choice for small businesses where multiple devices often need simultaneous internet access. It has been recognized as one of the best small business routers in the market.
