    Fast. Advanced.

    I wanted something more "Enterprise Grade" to replace my Asus AC86U router. (I have been using Asus flagship model routers for many years along with Merlin Firmware) But, Asus seems to have...hickups...with their firmware from time to time with bugs that take a long time to get fixed. I would hope that Ubquiti firmware is far more robust and tested.The EdgeRouter products is certainly for those who know how to setup network from scratch, knows CLI commands and terms and have worked with routers/switches such as Cisco etc. It is NOT a plug and play device. If you want more easy to setup and man

    Excellent router for prosumers and professionals alike

    The Ubiquiti EdgeRouter4 (ER4) falls somewhere in between a consumer grade SOHO router (NetGear, Linksys, etc.) and enterprise class (Cisco, Juniper). It supplies many of the features of enterprise grade hardware, such as a robust CLI, and is packaged in a durable, fanless metal box that is easily wall mounted. The SFP port is a nice plus when you need it.I purchased this product for two reasons: to better segment my home network and because it can handle Cox Gigablast's 1Gb downstream connectivity. I no longer have the time to build and maintain my own Linux or *BSD based router and this is t

    Got CenturyLink gigabit fiber? Here's your router.

    You know, the ironic thing about CenturyLink is they actually have a great product in their gigabit fiber. The problem is the routers they provide are just... well... not great. Let's just leave it at that.The EdgeRouter 4 is a superb replacement for the CenturyLink models (usually Zyxels). Duplex gigabit, tons of advanced options - hardware offloading while keeping Traffic Monitoring intact etc. I upgraded to this from the Ubiquiti ERX, which did a fine job, but lacked duplex gigabit over WAN, and Traffic Monitoring doesn't work at all with hardware offloading, which was annoying.Just like th

    Fantastic Router for Home with 50 Devices

    I bought this router to replace two seven year old Linksys wireless routers. I decide to go with a network upgrade to first separate the routing from the WiFi access and create as many wired connections as possible. Reviews of the EdgerRouter 4 were generally very favorable, so I decided to go with it as the foundation of the newly designed home network. I watched several videos on how to set up the router and followed them for the most part. When it came to the installation step the only problematic issue was figuring out the internet DHCP connection type (it ended up being a fixed IP address

    Compact with fast routing with hardware offloading.

    I purchased this unit to replace my ofSense box since my hardware is not going to be supported after v2.5. The unit itself is small and runs fairly cool. Feature wise I have found the unit to be extremely fast with hardware offloading enabled. The web based interface is practical for most home users, but all advanced features must be accessed via CLI which is also accessable via the web based interface of through programs like puTTy. The CLI commands take some getting used to. I have not found EdgeOS' command structure to be as intuitive as pfSense. I have also found that pfSense appears to be

    Handles 1Gbps internet without breaking a sweat

    I upgraded to this from the Edgerouter-3 Lite which I loved, I saw the massively improved specs of this one and wanted to have a backup router in case one died. It has no trouble maxing out my 1Gbps comcast connection. Watching the dashboard I never see the CPU in this thing get above 10% where the old 3 lite would frequently be at 80% if you were pushing it hard, this means lots of room to turn on monitoring features, VPN, routing protocols, etc. I have recommended the edgerouter 3-lite to everyone that gets a 1Gbps internet connection and complains that their "all in one" wireless router onl

    A workhorse

    I'm not extremely tech-savvy. Enough networking knowledge to set up almost any basic home router/switch you throw at me, but not enough to know terms like VLAN, PPPOE, NAT, etc. I run a small business dealing with a lot of computers, and I had wrongfully thought that a high-end home wifi router such as the RAX80, which is almost twice the cost of this router, would be more than enough for my needs. Turns out it got overloaded pretty quickly, with packet loss and general latency issues everywhere once all computers started to demand internet from it. As a last ditch effort I bought one of these
