I have numerous UNIFI products including Nano, Pro, mesh and mesh pro. The mesh units require you to hook to you lan and go into configuration and select able to work as a MESH which adds time to the deployment. The Beacon is configured out of the box and you literally plug it in and wait a few minutes and shows up in your controller. Select, upgrade, and the rest is done automatically. Mesh to base unit is 1ghz plus (reported, not actual) and download speeds exceed 300mbps on my iPhone 11 Pro. Compare this with the mesh pro a few feet away and it connects 600-800 and download speeds under 200. The mesh pro frequently disconnects, becomes isolated and requires maintenance to work. The Beacon HD works flawlessly. Positive Out of the box configuration simple Mesh connection superb Very fast upload/download Negative Not 360 beam. The unifi website has Antenna Radiation pattern that suggest 360, but clearly not the case. I'm trying to get signal to our patio and placed on the inter wall in our dining room behind a curtain so clean instal, however, very little to no signal using wifi analysis with high ping and downloads that were unusable to stream media. I attached a 1 foot extension cord and angled at wall and was able to achieve 70+ mbps. I'm keeping the unit because I'm so impressed by the clean implementation, but really not addressing my use case and will continue to use the mesh pro. If the mesh pro stayed stable I would be happy, but disconnects, skips heart beat, isolates etc routinely. Beacon externally is challenging because we have weather proof electrical outlets and I'm not convinced it has good weatherproofing.

Simple plug and play. I have 2 other access pints from Ubiquiti - one on the main flier and one for outside. I was looking to add one in the basement to improve the WiFi signal for my sons gaming. This product fit the bill perfectly. Unlike some of the other Ubiquiti products this was a very simple plug and play. Literally no setup other than deciding which outlet to use. Plug it in and within a couple minutes it's allocated as an access point on you network. Works great and looks good. Only downside is that that outlet now cannot be used so works best when you have an outlet to spare.

Works like a charm. No issues as an extender. Does its job and is plug and play. It’s stable and maintains consistent speeds.

9 month UDM set-up review: I had finally decided to upgrade my network and the UDM seemed perfect for a secure home network. My introduction to Ubiquiti was the security breach, followed by a wireless AP that disconnected every 2 days no matter where it was. I ordered and replaced that with a wired unit. Once I had my Vlans secure and passing media, all devices and routing configured with the assistance of some CCNA friends, I loved it! Then, during a regular monthly reboot, the system completely erased the config which is when I learned back-up doesn't really mean back up. Then 9 months later 3 of the 4 ports are dead and the 3rd party tech support team recommends me to a 4th party RMA service that is non responsive. A previous RMA was delayed more than a week because they claimed they were waiting for the broken equipment first. RMAs typically are sent and the failed equipment returned in that packaging as the RMA email stated. Now, I am both disappointed in Ubiquiti for not directly supporting its products but deflecting support to hundreds of tiny resellers. I am also disappointed in every person who recommended this product to me. I am now headed to the basement to dig out my trusty old $149 ASUS router that I wish I had stayed with. My advice, spend the money on real equipment, or get a decent simple inexpensive home router, there are no shortcuts. You cannot present a product as professional without a reasonable level of support. Update: After Ubiquity stepped in and replaced what seems to now have been a faulty UDM, everything has been great for over a year. new recommendation, buy direct from Ubiquiti.

Connected via mesh within a couple minutes and by putting it about 30 feet away from the router, really extended the quality of the Wi-Fi in that part of the house. The entire Unifi experience is amazing if you can stomach the price.

Ubiquiti makes the best networking tools there are period. This unit is just another example of that.

I have two AC Pros in the house and needed to fill in a area of the house upstairs that had a weak signal. This device really pulled it all togetther. Took 5-10 minutes to set up - adopt, update, provision. No need to do any configuration on it, as it just joined the existing network seamlessly. But, the real magic is how well it worked. Now i get full bars throughout the house, with the occasional drop of one bar, but even then it usually goes right back to full. Tested speeds in each room and it's consistently fast everywhere. The existing APs work well, but they needed something to pull them together more and round out the coverage. Fantastic! Btw, you can also turn off the light, set it to any color, and/or set the brightness level of it.

Another win from UniFi. Despite my excellent UniFi NanoHD AP’s I had some WiFi dead-spots on my homes second floor attributed to current suboptimal placement. The ideal solution would be to run cat cabling to a room with poor connectivity or install another AP close by. Let’s face it, sometimes you just don’t feel like crawling into the hot attic and drilling holes in your ceiling below. In my scenario I have spray foam insulation in my attic floor so my visibility of electrical wiring is nil and makes me hesitant to drill. So I opted for choice B, purchasing the UniFi BeaconHD. This repeater works well, was easy to install and required only a little trial and error to select the best location. You will get the best result if the beacon is located close enough to the AP wireless link that you have at least 90% signal strength. This will maximize your speed and stability. Overall, 30 minutes of time increased my sons Xbox network speed from 17 mbits/s to 285 with 100% signal strength in his room.
