It’s a normal diagnostic tool, normally used by network professionals to make sure two computers that are supposed to be talking are able. Netstat output is not conclusive evidence that your computer has been hacked.

Roku Internet speed is poor? Here’s what to do

If your Roku Internet speed is poor, or you think it might be inadequate, there are some things to do about it. Here’s how to run a Roku Internet speed test and how to interpret the results it gives you.

Best way to store Lionel trains

Best way to store Lionel trains

I was talking to a friend the other day about trains and especially about rust. He was very concerned about being able to get the trains out next year and enjoy them without having to clean or refurbish them again. Here’s the best way to store Lionel trains.

The best way to store Lionel trains is in the living space of your home. Try to avoid storing them in a garage or attic if you can. A basement is OK if it’s not too damp. The box they came in is ideal, but there are acceptable substitutes. You also need to be careful how you wrap them.

Increase powerline speed with these weird tricks

Increase powerline speed with these weird tricks

For Christmas we replaced the entertainment center in our living room we’ve had for 10 years. That meant disconnecting and untangling 10 years’ worth of wiring. I also ran into some problems with my networking. One problem was absurdly low speed. So I looked into ways to increase powerline speed. While it’s still not great, it’s much more usable now.

Generally speaking, to increase powerline speed, you need adapters with a top speed that seems reasonable to you. Assuming you have fairly quick, up-to-date adapters, you should plug them directly into the wall, place them as close to each other as possible, try to avoid using them on circuits that have arc fault breakers on them, avoid having motors and other heavy appliances on the same circuit as the end that plugs into your switch or router, and, ideally, plug them both into outlets on the same circuit breaker.

Outlet sparking when plugging in? What to do

Outlet sparking when plugging in? What to do

An outlet sparking when plugging in is scary when it happens, so I don’t blame you for asking. Is it normal to see a spark when you plug something in?

A spark, also called an arc, happens when electricity jumps from one surface to another, and is usually too small to even notice. If you routinely see a big spark when plugging something in, you need to do something about it, but the cost is frequently very low or even free.

AT&T U-verse bridge mode

AT&T home gateway devices don’t have a true bridge mode that you can use if you want to use your own router with their service. But there is an acceptable substitute. So here’s the closest thing you’ll find to AT&T U-verse bridge mode and how to enable it. This also works with AT&T Fiber and everything else AT&T calls AT&T Internet.

Bing SEO optimization: An untapped resource

SEO generally centers around Google, because it’s the dominant search engine. But just because they ignore Bing doesn’t mean you should. Bing SEO optimization is similar to Google, but not quite the same. I find Bing is an untapped resource, and it has benefits besides the increase in search traffic it provides.

Computer power cord AWG: Why it matters

Computer power cord AWG: Why it matters

If you look at your PC power cord really carefully, you’ll see a number stamped on the side followed by the letters AWG. What does a computer power cord’s AWG mean, and should you worry about it? What AWG makes a good gaming PC power cord?

With a typical desktop computer, even a light-duty power cord is sufficient and you don’t have to worry about AWG. High-end computers like servers or gaming PCs with high-power video cards in them do benefit from a heavier-duty power cord, such as 16 AWG or even 14 AWG. Using a heavier cord than the manufacturer specified won’t cause any problems, but a too-light cord can cause various issues.
