How DDoS attacks work

Yesterday, half the Internet was broken. I knew something was wrong when I couldn’t get into Salesforce to check on a support ticket for my biggest customer. Another member of my team sent us a warning that a big DDoS attack was happening, and not to count on being able to issue very many quotes today. So what, exactly, is a DDoS attack and how do DDoS attacks work?

I suppose there’s another question to ask too: What can you do to avoid being part of the problem? We’ll save that for the end.

AT&T U-Verse vs Charter Spectrum Internet

AT&T U-Verse vs Charter 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 to become an option, but I switched once I did. I’ve been a Southwestern Bell/AT&T customer for a good 17 years. Over the years I weighed it and AT&T U-Verse vs Charter Spectrum.

Recently I switched to Charter though. There are pros and cons to each of them, so I thought going through them might be helpful. Keep in mind Charter recently acquired Time Warner Cable and Bright House Networks, so this applies to former Time Warner Cable and Bright House areas as well.

Adjust DD-WRT TX power

Adjust DD-WRT TX power

I had a DD-WRT router that was dropping a lot of packets. I got a lot of errors and that caused poor playback in Netflix and especially MLB.tv. It wasn’t a bandwidth issue. My wireless network connection was just too noisy. I had to adjust my DD-WRT TX power to fix it.

I probably adjusted it the opposite way you would expect. Read more

Advantages of Windows 10

Advantages of Windows 10

Now that Windows 10 is out, the questions I see most frequently are why someone should upgrade, or what benefits they get if they upgrade, or if there indeed is such thing as advantages to Windows 10.

While I understand the skepticism, and I think most people probably should wait a few months before upgrading a Windows 7 machine that’s working well, there are a number of compelling things Windows 10 has to offer.

Decrease your Roku resolution to save bandwidth

Decrease your Roku resolution to save bandwidth

From time to time when I’m watching baseball on my Roku, I’ll get a lot of buffering and, in extreme cases, a message stating that I may have insufficient bandwidth. If you have the same problem, the best fix for this to to decrease your Roku’s playback resolution. Or if you’re subject to a data cap, decreasing your resolution helps you stay under that too. Here’s how to change your Roku resolution.

The picture will suffer, but I’d rather watch a lower quality picture than none at all. You may also need to resize your Internet connection, but you can do this trick immediately, and for free.

How to size your Internet connection

So I understand ISPs are upselling connection speeds saying it’ll make Netflix work better. That’s a nice theory. But if you’re already over 10 megabits, there’s a decent chance your connection speed won’t do much for Netflix at all. Here’s how to size your Internet connection. Read more

Keep cordless phones from interfering with Wi-Fi

Keep cordless phones from interfering with Wi-Fi

Long ago, when dinosaurs roamed the earth and knights in shining armor fought them, people had landlines. And they plugged cordless phones into them. Everything was great. Then phones started using the 2.4 GHz and 5 GHz frequencies. Wi-Fi came out using the same frequencies and the two interfered with each other. Now, it seems increasingly difficult to keep cordless phones from interfering with Wi-Fi.

Many people have neatly solved the problem by using cell phones exclusively. But what if that isn’t an option? You’re actually in luck, and you don’t have to dig up a 20-year-old 900 MHz phone and try to find a battery that works in it.

Build the best, most secure wifi in your neighborhood

My neighbor asked me for advice on setting up wi-fi in his new house. I realized it’s been a while since I’ve written about wi-fi, and it’s never been cheaper or easier to blanket your house and yard with a good signal.

Blanketing your house and yard while remaining secure, though, is still important.
