A few months ago I made some observation of how Grandstream had come to be in-use around my home & office. I especially appreciate their surveillance gear. The GVC cameras and NVR are in 2/47 service and have served us well the past couple of years.
That said, two problems have cropped up recently that bear examination.
I also thought, hoped even, that it was a relatively standard use of Androids USB-On-The-Go capability. Meaning that I had hoped it would serve an Android tablet just the same as it handled Chromecast, providing power + Ethernet. That’s where I was wrong.
Everyone wants great Wi-Fi. That much is a given. Our homes occasionally make achieving this difficult, either by way of their sheer size or manner of construction. This is a cautionary tale about a project I undertook around our home, and its unexpected impact on our Wi-Fi.
In recent years wireless mesh networks have become quite fashionable. And why not? Providing reliable coverage in a large home may require multiple wireless access points. Pulling Ethernet cable to each of those locations (yeah, baby!) is beyond all but the most ambitious of DIY homeowners.
For the average Joe installing one central router, then plugging in a couple of more distant wireless repeaters seems so much easier. That’s a Saturday morning chore that might well ingratiate you with the family.
USB-OTG is very handy. It allows someone to connect a variety of different USB devices to a tablet or mobile phone. Most often I've made use of a simple USB OTG cable to connect a flash drive or USB headset…
CERT, a US Federal government agency tasked with cyber-security research, has issued an alert advising consumers to stop using various models of Netgear routers. These devices are subject to a trivially simple command injection exploit. Ars Technica has a nice overview of the matter.
Normally I’d have literally nothing to say about this, since it simply doesn’t impact us. Wanna know why it doesn’t impact us?
We don’t use a consumer router that runs closed source firmware. We don’t think that you should either. In fact, you probably shouldn’t let your friends and family use that junk either.
Perhaps this holiday season, and all of the travelling & visiting that goes along with it, presents an opportunity to help someone unsuspecting secure their home network.
Over the years I’ve come to admire 802.3af standard power-over-Ethernet (aka P.O.E.), even for small- or home-office applications. What follows is an introduction to the topic, and some novel ideas about its use in possibly unexpected applications.
IEEE 802.3af Power-over-Ethernet is the industry standard approach to delivering DC power to network attached devices. Given a P.O.E.-capable switch, or a P.O.E. inserter, DC power is delivered over the same Ethernet connection that provides connectivity. Thus one wire is all that’s required to a distant device on the network.
