What happened to Charter Communications?

The name Charter Communications has largely disappeared, after years of being one of the largest cable companies in the country. So what happened to Charter Communications? When did Spectrum buy Charter? The answer probably isn’t what you think.

Charter Communications still exists as a legal entity. It just transitioned to using the Spectrum brand name starting in 2014.

Upload faster than download? Try this

Is your upload faster than your download with your Internet connection? This is a fairly obscure problem that seems to have started happening again. Here’s how to test to see if you’re actually having a problem, and how to fix it.

If your upload speed is slightly faster than your download speed, it’s not worth worrying about. On a symmetric Internet connection where the two are supposed to be the same, I expect to see them within about 10 percent of one another, and if download slightly outpaces upload, it’s not hurting anything. But if upload is faster when it’s supposed to be slower, something weird is going on.

AT&T Gigabit not fast? How to troubleshoot

Last week I traded some tips with a neighbor who signed up for AT&T Gigabit on my recommendation. His speeds just weren’t as fast as mine. Is your AT&T Gigabit not fast? Here’s some advice that may help.

I’m able to consistently get speeds in both directions above 900 megabits on my AT&T gigabit connection, at least on my best hardware. Some of my older hardware lags behind that a bit, but still does much better than 500 megabits. So I’ll share my secrets.

DNS over TLS: Protect your network with Ubuntu

Right now the only consumer OS that supports DNS over TLS is Android Pie 0r newer. But that doesn’t mean you can’t run DNS over TLS yourself to protect your DNS privacy. Here’s how to implement a local DNS server that uses TLS to talk to upstream DNS servers to keep your ISP and other hostile third parties from seeing your DNS lookups. As a bonus, it caches your requests to speed up your Internet connection, and you can filter out malware domains with it.

There’s a lot to like with this setup.

AT&T Internet vs Spectrum Internet

I’ve had high speed Internet for about as long as anyone in my ZIP code–as soon as DSL was available, I signed up and paid through the nose for it. It took a while for fiber optics to become an option, but I switched once I did. I’ve been a Southwestern Bell/AT&T customer for a good 20 years. Over the years I weighed AT&T Internet vs Spectrum Internet. And for a while, I switched.

I switched to Spectrum in 2016, then back to AT&T in 2018. There are pros and cons to each of them, so I thought going through them might be helpful. Keep in mind Spectrum encompasses several legacy companies. Charter Communications started re-branding itself as Spectrum soon before it acquired Time Warner Cable and Bright House Networks. Of the three, only Bright House Networks had a good reputation, but Bright House had low name recognition. Hence the use of the new name.
