Google Fiber speed test of EdgeRouter Lite 7
Many moons ago, I replaced my Google Fiber Network Box with a UBNT EdgeRouter Lite router at our house in Provo, Utah… and never looked back! With a street price of under $90, the ER-Lite was a tough act to beat for the money. But later, when Ubiquiti Networks released the newer EdgeRouter […]

Kernel Version vs Firmware Version 6
In March of last year, I published this article claiming that the latest (at the time) DD-WRT builds based on the Linux 2.6 kernel (K2.6) ran faster on a Linksys/Cisco E4200 router than their K3.x counterparts. Since then, I’ve heard apocryphal stories from some in the DD-WRT forums that the […]

AC Infinity S3 fan
If you’re like most homeowners, you probably keep your receiver, amplifier, router, network switch, or any other electronic equipment inside a cabinet… which means you have a heat problem. Heat is the enemy of electronics, and circulating air through and around anything electronic is vital to its performance and longevity. This is the cabinet […]

If you’ve ever set up a Ubiquiti UniFi access point, such as the UBNT UAP, UBNT UAP-PRO, or UBNT UAP-AC-PRO, you’ve had to run UniFi Controller software required to adopt, configure, and manage your UniFi devices.

Thermostats have come a long way since the days of the gold-colored round Honeywell dial thermostats at your grandma’s house.

But now even those manufacturers are shipping 2nd or 3rd generation hardware… meaning that […]
