AT&T provides a residential gateway when you subscribe to U-Verse or AT&T Fiber. It’s pretty easy to use, but lacks a lot of features we expect in routers these days. So you may be wondering: Can I use my own router with AT&T U-Verse? Yes. Yes you can. Here’s how to use your own router with AT&T U-Verse or AT&T Fiber.
AT&T’s default wi-fi passwords aren’t the worst I’ve seen, but they aren’t super-secure either. So here’s how to change an AT&T U-Verse wifi password. The same trick works with AT&T Fiber, since it uses the same residential gateways.
Is there a virus on my phone? Or your phone? I can’t know for certain, but probably not. Here’s what to do if your phone says it has a virus and wants you to visit a web page or pay someone money.
I’ll tell you what you really need to do, and I’ll even show you a neat trick so you’ll see fewer of these messages. And none of this will cost you anything, either.
Does retail count as sales experience? I think it depends, but there are certainly ways you can make it count. Here’s how.

The lowly Countif function is one of the most useful tools for data analysis you’ll find in Excel and other spreadsheets. It’s also not all that well understood, I find. Knowing how to use it sure has made my job much easier since 2013, so I think there’s a chance it will help you too. Here’s a Countif example to show you how to use it.
Sometimes you’ll hear insurance professionals, banking professionals, computer security professionals, and other people who deal with risk talk about inherent risk and its counterpart, residual risk. If these are unclear to you, or you just need a refresher, you came to the right place. Let’s take a look at a simple inherent risk definition and example, as well as residual risk.
Every couple of months or so, we have to collaborate at work on a Microsoft Word document and submit it without all the distracting markup in it. And it seems like it always takes four of us half an hour to re-figure out how to accept all changes in Word and remove the comments. This applies to Word 2007 and all newer versions.
Sometimes I also find the tracked changes and other markup causes weird problems, and the fastest way to make them go away is to get rid of the markup.
So I figured it might help someone. This is something that either takes you 30 seconds or 30 minutes. If you don’t do this every day, it’s likely to take too long. This is for those of you who can’t do it in less than 30 minutes.

My boss’ management is clamoring for metrics. They want to know, at a glance, what we’re doing and how far along we are. Sounds like a job for stacked bar charts in Excel to me. So here’s how to create a stacked bar chart in Excel.

Here’s a good question I heard the other day: What’s the difference between a CPU and cores, or the difference between the number of CPUs and the number of cores in a system? The CPU vs core or core vs processor distinction, it turns out, is subtle.
As far as the operating system is concerned, there is no difference, but I’ll explain why. For you, there might be a difference.
I’ve had a long history with wrist pain from typing, brought on by carpal tunnel syndrome or repetitive stress injury. People sometimes as me to elaborate, so I’ll elaborate on beating carpal tunnel. I was able to beat it without surgery, and you may be able to as well.
