Ubiquiti Unifi UXG-Max Router: The Most Boring Installation in Memory

The transition to AT&T Fiber meant jumping from 60/10 mbps service to 500/500 mbps service. Our old router was SmallWall on a recycled HP T620 Plus thin client. SmallWall is a fork of m0n0wall, which I used for years previously. And a history lesson, m0n0wall was the progenitor of pfsense.

Alas, that little hardware/software combination simply wasn’t up to this new, and much faster, ISP. It could only manage to pass 120 mbps. The CPU tracking in SmallWall didn’t show it to be overburdened. I suspect other aspects of the hardware were the problem. It has a dual-ported Intel NIC. They’re 1G ports, connected to the host via a PCIe x4 connector.

UXG-Max

I could have swapped out the T620 Plus for something newer and faster. However, I decided to extend our installation of Ubiquiti Unifi gear by adding their Unifi UXG Max router. That would allow me to see the ISP/router performance in the Unifi UI, which is handled by the Unifi Controller app running on a local Raspberry Pi400.

We came to use the Unifi line by way of their Wi-Fi access points. That was the end-state of what had been a long-running search to deliver reliable Wi-Fi. When our Ubiquiti PowerAP N died we deployed Unifi AC Pro access points. So began our foray into “software defined networking.”

Rewiring the Network Core: Part 2 – Beats, Wi-Fi & Brittle Cables

As was mentioned previously, I’ve been upgrading the network installation in the central hall of our home. The new vertical rack cabinet is now installed.

The paint job is a little splotchy. A contractor we had working for us the other day commented on the “neat cloud effect” I had achieved. I had to admit it wasn’t intentional, but it’ll do for now. It’s mostly hidden from view. At least the color is a good match for the wall.

Vertical Rack

As you can see, power is still being supplied by way of a pigtail out the bottom to a nearby outlet. That’s temporary. It will be replaced by a wire fished through the wall.

You can also see the holes in the floor where network cabled once passed from under the house. I need to get wooden plugs to fill those holes. The cables now run into the wall, onward to the patch bay in the cabinet.

Further Adventures in Power-Over-Ethernet Land: POE Extenders

For the past month or so we’ve had a couple of foster dogs on the property. They are a Husky and a Rottweiler, both less than a year old, who were wandering nearby and I (unthinkingly) took them in. This has caused me to want improved coverage of the yard by our security cameras. I need to keep an eye on them so they don’t become destructive.

In particular, I want to add another IP camera to our front porch. The two existing cameras were intended to monitor our on-street parking. So, they are west facing, pointing toward the street. I’d like to add one looking at the porch and the front door. That view would include several chairs. The Rottweiler is inclined to play with the cushions from the chairs on the porch, which I simply cannot allow.

We’re a Unifi House

Each of the existing cameras has a Cat 5e home run to the Ubiquiti Unifi POE+ switch in the central hallway of the house. I selected the Gen 2 managed Unifi switches for the best combination of price, POE+ and a fanless design. I like silent.

While I could run another Ethernet lead, that would be tedious, and hardly seems necessary given the limited bandwidth and power requirement of our Grandstream IP cameras.

Raspberry Pi as a Wi-Fi Bridge

Raspberry Pi are fun little devices. They’re a bit like rabbits in that they tend to multiply. We started out with one as a replacement for a failed Squeezebox, and now have 6 or 8 of them around here. Most are media players running PiCorePlayer. The availability of the Pi4 inspired me to deploy one as a media server, running PiCorePlayer with Logitech Media Server. Yet another Pi4 hosts our local instance of Home Assistant.

Of course, with several RPi deployed it only seems sensible to have a spare on hand. So I usually have a Pi3 and Pi4 readily available for whatever tinkering occurs to me. Earlier experiments with Dicaffeine for example.

We recently installed a new television in our living room. That room had been without a TV for years, but it was decided that a particularly large open wall would be a good place to put a larger TV. A new Vizio M65 now fills that void.

The Vizio M65 is the larger and newer brother to the M50 that’s been in our family room for several years. In 2016, 50” was the largest that was deemed acceptable, both in terms of price and spousal approval. In 2020, it seems that 65” is the new normal and price/performance sweet spot.

The new TV is installed. It connects to our Wi-Fi without issue. That satisfies the requirement for access to Netflix, Amazon Prime, CBS All Access and Disney+.

The Ubiquiti LiteBeam Wireless Bridge Looks like Fun!

Occasionally something crosses my path that looks like a fun toy. I find myself wishing I had a project to justify the purchase. Such is the case with the Ubiquiti LBE-5AC-GEN2-US LiteBeam Wireless Bridge.

A pair of these devices form a long-range wireless bridge operating in unlicensed spectrum. It fits right in with our existing Unifi Cloud Key and AC Pro Wi-Fi APs. Best of all, at under $70 per end, it’s really affordable.

LiteBeam 5AC Gen2

Ideally, I’d use a pair of these radios to gain access to the Tachus fiber internet service that runs up Harvard Ave. That’s 1.43 miles (2.29 km) due west of our home. The Ubiquiti setup tool shows that we could achieve 250 Mbps over that link.

Rebranding Networks: Wi-Fi 5 vs 5G

The hype around 5G mobile networks seems to have the Wi-Fi Alliance crowd a little nervous. In early October they launched a rebranding initiative to make the alphabet soup of Wi-Fi easier for grannies to understand. Were once we refereed to 802.11a/b/c/n/ac and/or 802.11ax…now, to be Wi-Fi certified, the correct terminology is:

  • Wi-Fi 4 (formerly 802.11n)
  • Wi-Fi 5 (formerly 802.11ac)
  • Wi-Fi 6 (formerly 802.11ax)

The entire guide to this new marketecture, which includes a library of symbols for use on packaging, is here. It’s worth a glance. Remember, the point of the exercise is to bring clarity to the oh-so-confusing world of Wi-Fi.
