Upgrading the home network to use Ubiquiti products

Posted on Wed 13 March 2019 in Technical Solutions

Routers past

I am not known for being gentle with routers at my house. I have pushed many consumer grade routers to their limits and ended up replacing them for newer models or competing models. My most recent model was an ASUS RT-AC66U. I bought this in 2015. It is one of the longer surviving routers in the house.

Since I started working from home though, I've been noticing more problems. These include randomly dropping all wireless connections, randomly losing connection to the cable modem and frequently needing reboots to fix these problems. The issue that finally made me start looking for another replacement was when the entire router would reboot when a new wireless device connected to the network.

This was especially obnoxious when family members would come home and their phones would reconnect to the home network. On more than one occasion a work call was dropped, a college course interrupted or a review session with coworkers disconnected.

I've also found myself adding smart home "things" to my house in the past few years. I'd told myself that I didn't need smart plugs, smart lights, voice assistants, and the like, but I received a free voice assistant at some point. I set it up and the family got hooked. One voice assistant became two then more. I attached smart plugs to Christmas lights "as an experiment" and found it worked way better than I expected. Christmas ended and the plugs were re-purposed. I brought in smart lights and out fitted my office with those. I have more, but haven't yet expanded to other rooms. It's coming though.

In short, I have more devices than ever connected to the network and the wireless router I had didn't seem up to the task of handling all of it.

It was time for an upgrade. I didn't want just another router that I'd have to replace in a few years though. I wanted something high quality and that could handle anything I through at it.

Enter Ubiquti

I don't remember what brought [Ubiquiti][ubiquiti] to my attention years ago, but I was immediately impressed with the hardware, the reviews and the price point. It is not a home router, but it's also not a five figure price.

I did some research I what I'd need in the house. I needed to be able to support several wired devices, even more wireless ones (computers, phones, tablets, and home automation devices). I wanted to have a guest network like the previous ASUS, so that I could easily give visitors access to the internet without giving them access to everything on the network. I also wanted to segregate all of those smart devices to their own network.

I am trained as an information security professional. I understand the risks that all of these devices can add. It's a lot of little mini-computers on the network. I don't want an outlet plug compromising my house. I also don't have top secret data, so a little risk for the sake of convenience is ok to me. If I could put these devices on a network that is seperate from both the main network and the guest network, that'd be good for my purposes.

Ubiquiti Devices

After a lot of research on the devices Ubiquiti offers, I picked out the ones that would be used. I'd be using the UniFi branded products instead of the Edgemax branded products. From everything I was able to find, the hardware between the two brands is how they are managed.

I am not a network engineer. I work with some great ones at work and they speak another technical language entirely. As useful as it'd be to know more in that area for work, that's not a goal I wanted to pursue for a home project. I went with UniFi because of it's easier management with the UniFi controller.

I went with the following devices

Security Gateway

The security gateway is the router the handles the network. It's much smaller than previous routers I've had. The purpose of this product is to provide routing, not be the device everything in the network plugs into. That's the switches.

The cable modem plugs into WAN1 and the switch plugs into LAN1. That's it. Nice and simple.

24 port switch

The 24 port switch is the first switch I bought for this project. It was a mistake. The mistake was mine though. The Access points are powered via power over ethernet. This switch doesn't have that. The best I can come up with for how this mistake was made is that I had both the PoE and non-PoE versions open when I went to order and put the wrong one in my cart.


That said, it ended up being a happy mistake. I have more wired devices than I realized. Previously, I had a router and a couple small switches scattered around the house to allow multiple devices to be plugged in. If I'd just ordered the single 24 Port PoE switch, I'd have used well over half of the ports immediately between the existing devices and the new access points.

My solution was to keep this switch, and only plug in the wired and non-PoE devices into this switch. Anything that needed to be powered via PoE would go into the PoE switch.

24 port switch PoE

The 24 port PoE device is slightly deeper than the non-PoE version. It also has case fans. I am using this device to power the access points I purchased. It was originally going to power the cloud key too.

Access Points

I bought a 5 pack of AC Pro access points. As I mentioned, these are powered via power over ethernet. That means I needed to run wires to locations around the house. That's an exercise I don't want to repeat.

I've put up three of the five access points initially to see how much coverage they provide to the house. So far, I am pleased with how they are performing. I'm not sure where the last two will go yet, but I'll find a spot eventually.

These access points are handling the three networks without any issues. The trust home devices are on one network, the smart home devices are on another, and a third guest network is used occasionally with no issues.

Cloud Key (Gen 1)

This is the device I wish I'd researched a little more before purchasing. I see it's purpose, but I don't need it. I can run the UniFi controller on my Ubuntu server. It took a little bit of work to get it installed because of port conflicts with GitLab and poor error messages, but once that was figured out, it works just fine.

My other complaint about the first generation cloud key is that it just hangs from the switch. The second generation is mountable (and performs more tasks for other) Ubiquiti products. I purchased the first generation though and don't think I'll ever use it.


The set up of all devices is very simple. Plug it in, set up your management account on the UniFi controller, adopt the devices and you are set up. A little configuration is needed to set up wireless networks, but that didn't take a lot of work either.

From the controller, updating the firmware of all devices is simple. If there is an update, the controller lets you know and you click "update". Five minutes later, the device reboots with the new firmware and everything works. I was able to update everything within thirty minutes.

Be aware of which devices are plugged into what. You don't want to reboot an upstream device before the down stream ones are finished. For that reason, I updated the access points first, then the switches, then the security gateway.

Since everything was set up, I haven't been disconnected from the cable modem once. I haven't had the entire wireless network shutdown when a family member came home. I haven't had any spots without coverage in the house.

In fact, I have a brand new first world problem. A couple of the smart plugs I have can only be configured on the 2.4Ghz band. The three access points I have cover the entire house in a 5Ghz signal. To configure these plugs, I need to step out into the yard to get outside of the 5Ghz range.

The amount of details available in the UniFi controller is amazing. I can see signal strength of all wireless network devices. I can see nearby wireless networks that I couldn't see with the previous router. I can see traffic patterns (I watch a lot of video services). I even have the intrusion prevention system enabled because my internet speed isn't fast enough to be impacted by the load this puts on the security gateway. There is one persistent IP in Europe that likes to scan me. Hi Netherlands! I see you!

What's next?

So far, everything I've thrown at this new set up has handled it like it was nothing. That makes sense. These are business class products and are designed to handle way more than I should be able to throw at it as a home user. I like a challenge.

What's next though? I'd like to get even more information from the devices. A true monitoring solution for the entire home network or at the least the network equipment and the server. I've been investigating the TICK stack for gathering metrics. I'll see if I can set something like that up in a way that I like.

I'd also like to expand wireless coverage out to the shed. I'm not sure if I can do that with the access points though. I don't want to run an ethernet cord out there (and bury it). That's really far down on my wish list though.
