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

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. Forgetting the network and reconnecting didn’t help–I’d get the message that Windows 10 can’t connect to this network.

The problem seemed to be in the power management.

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

A DD-WRT USB print server

A DD-WRT USB print server

If your router has a USB port and is running DD-WRT, you can turn it into a DD-WRT USB print server. It can still do wireless duty while it allows your computers to print to your wired USB printer over your wired or wireless network. It’s not very intuitive or user friendly, but it works. Here’s how to set it up with Windows 7. Other Windows versions will be about the same.

The settings saved on this computer for the network do not match the requirements of the network

If you replace your wireless router with another one, your Windows machines may give you a red X along with this error message when you try to reconnect: the settings saved on this computer for the network do not match the requirements of the network.

The quickest, easiest fix is to forget the network and reconnect. Here’s how to forget a network in Windows 7, and how to forget a network in Windows 10.

Linksys EA6200 DD-WRT installation

Linksys EA6200 DD-WRT installation

I picked up a couple of refurbished Linksys EA6200 routers this past weekend. For whatever reason, DD-WRT isn’t officially supported on them, though it does seem to be a popular DD-WRT router. A lot of people make the upgrade far more difficult than they need to. With some simple hacks, Linksys EA6200 DD-WRT installation is pretty straightforward.

I came up with an 18-step process that I simplified just as much as I could. Unlike some methods I’ve seen, I don’t have you editing any binary files or creating custom startup scripts.

Why MAC address filtering doesn’t help security

The other question that came out of my recommended DD-WRT settings was why not filter MAC addresses. I hate to be flip, but MAC address filtering doesn’t help, so why bother?

The reason is because your MAC addresses are broadcast as part of the network traffic, and it’s unencrypted. So your MAC addresses aren’t any secret at all. So it doesn’t do any good. One could argue it doesn’t do any harm. But it adds an extra step every time you put something on your wireless network. Why go to the inconvenience if you don’t gain anything from it?

Why hiding your SSID makes your security worse

I got a couple of questions about my recommended DD-WRT settings, but I’m going to start with the question about why not to hide the SSID. It actually turns out that hiding your SSID is bad for you, and makes your security worse. I’ll explain.

HP Compaq 6910p upgrades

HP Compaq 6910p upgrades

I spent some time exploring HP Compaq 6910p upgrades because used HP Compaq 6910p laptops are dirt cheap these days. I picked one up for $75 as an alternative to a Black Friday cheapie.

If you look for one yourself, either look for one with a valid Windows 7 or Windows 10 license on it, or get one at a deep enough discount to make it worth your while.

Here’s what I did to turn an outmoded laptop from 2008 into something better than what I could have bought on Black Friday.

Recommended DD-WRT settings

Recommended DD-WRT settings

I’ve been asked a few times now for my recommended DD-WRT settings, or at least my good-enough settings. I think that’s a great idea, so I’ll walk through how I configure a DD-WRT router. Follow these steps and I can almost guarantee you’ll have the most secure network on your block.

For the purposes of this tutorial, I am going to assume you are configuring DD-WRT as your primary router.

Lenovo and Best Buy team up for a $149 laptop this year

Cheap laptops are nothing new this time of year–they’ve been practically a holiday tradition since 2002 when Sotec released a decent laptop for $900, which was jaw-droppingly low for the time–but this year, Best Buy is selling a Lenovo Ideapad 100s for $149.99, which, while not jaw-droppingly low given the number of $199 laptops that were available last year, is still the cheapest name-brand laptop I’ve seen. Note: Best Buy has since raised the price to $199, but Ebay has limited stock of the same item for $129.

I’ve seen some reviews, but there is one thing I haven’t seen anyone bring up yet: This is a netbook in every way, except I think we’re supposed to call them cloudbooks now. So keep that in mind. The machine is probably worth $149.99, but it made some compromises to reach that price point.
