Can’t connect to this network? Here’s the fix.

After upgrading to Windows 10, when I unhibernated my laptop the next morning, my wifi connection didn’t work. The connection dropped and I couldn’t reconnect. Forgetting the network and reconnecting didn’t help. Any time I tried to reconnect to my wireless network, I’d get the message that Windows 10 can’t connect to this network.

The problem seemed to be in the power management.

0xc1900201 error installing Windows 10

Are you getting a 0xc1900201 error installing Windows 10? I got both that and 0xc1900200. Here’s how I fixed it.

I upgraded my venerable Dell E1505 to Windows 10 over the weekend. It was harder than it needed to be, but I got it running. It’s an old machine, but for some tasks, it can handle Windows 10.

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

SSCP vs CISSP

SSCP and CISSP are both (ISC)² certifications. I get a lot of questions about the two of them, especially about SSCP, as CISSP overshadows it. So let’s look at SSCP vs CISSP.

Don’t close your 401(K)

Dave Farquhar Investing , , ,

So the UK voted to leave the EU, key political figures resigned, North Ireland and Scotland might want to leave the UK, and the stock market went into a free fall. What does it all mean? I don’t know, and nobody does. But don’t panic and close your 401(K) or move all the money into bonds.

The first successful home computer: Commodore VIC-20

What was the first successful home computer? Some people would argue it was the Apple II, the TRS-80 Model I, or perhaps even the Apple I. But I argue it was Commodore’s VIC-20.

Maybe I’m biased. I was a Commodore fan growing up and my first experience with a computer was probably on a VIC-20. But I think I can make a case.

Types of Lionel knuckle couplers

There have been three major types of Lionel knuckle couplers produced since resuming train production in 1946. Lionel knew it would have to make a splash when it brought its trains back after the end of the War, and the knuckle coupler was one of the keys.
