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.

Grandstream Revisited: Time For Some Tough Love

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.

Argh! Google’s Neat Ethernet Adapter For Chromecast is Proprietary

You may recall a month ago when I stumbled across Google’s way-cool power supply + Ethernet adapter for  Chromecast. At just $15 I thought it novel and a great way to give Chromecast the reliability of a wired network connection. That it is.

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.

A Cautionary Tale of Meshes & Networks

ubiquiti amplifi 300pxEveryone 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.

Ooohhh! This looks cool: USB Charger with a Built-in Ethernet Adapter!

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 to one of my devices.

You can also use a USB hub to connect multiple devices, all while keeping the tablet powered. I have on occasion connected a USB headset or Blue Yeti microphone. These I use in conjunction with Audio Tool.

Today I discovered that Google offers a USB charger that has a built-in Ethernet adapter. Called the Ethernet Adapter for Chromecast, it’s just $15 from the play store!

Ethernet Adapter for Chromecast

This is fantastic since it eliminates reliance upon WiFi as the primary means of connectivity! That could make many things, admittedly obtuse things, that I might wish to try more reliable. As I’ve stated previously, wherever possible I prefer to leverage Ethernet over WiFi.

I simply had to have one of these for use with my new nVidia Shield K1 tablet! There’s an open question as to whether it will work with the K1, It only delivers 850 mA, which may not be enough for some devices. At just $15 it’s a risk I’m willing to take. More news to follow once the goody arrives.

Netgear Routers Hailed as Dangerous – Here are some alternatives worth considering

netgear-R7000CERT, 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.
