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. Continue reading Adjust DD-WRT TX power

Moving SSH off port 22 doesn’t do much for security

A week or two ago, a stranger approached me with some advice about securing routers: move SSH off port 22.

Since arguing with strangers is what the Internet was apparently invented for, I’ll argue against the benefits of moving SSH off port 22.

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.

Use guest networks to secure IoT “smart” devices

A neighbor asked me about a recommendation Steve Gibson and Leo Laporte made a couple of weeks ago about securing your IoT household “smart” devices, like doorbells, thermostats, televisions, and anything else that wasn’t traditionally computerized, by putting it on a guest network.

The short answer is yes, it’s something you should do. It doesn’t make them perfectly safe, but it’s the best you can do, so you should. But I would do it a bit differently from Gibson–I think the ideal setup has two guest networks.

When DD-WRT doesn’t work with Charter

I set up a DD-WRT router on Charter’s Spectrum broadband, and had a hard time getting it to work. It wouldn’t pull an IP address on the WAN side, or it would pull a 192.168 address rather than a Charter public address.

Here’s what I had to do to fix it.

TP-Link TL-WR840n vs TL-WR841n

If you need an inexpensive DD-WRT compatible router, TP-Link is probably your best choice. But there are some big differences when you compare the TL-WR840n vs the TL-WR841n.

I’ve been running the TL-WR841n for more than two years, so I’m familiar with it. I’ve considered supplementing it with a secondary router, and the TL-WR840n was one I looked at.

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.

You might need a new router

Last week the New York Times, of all places, wrote a nice article about routers. If your wi-fi at home is bad, they say, think about picking up a TP-Link Archer C7 router.

A longtime friend asked me a week or two ago about routers, and I recommended a TP-Link Archer. Last week, it arrived, and he told me his wi-fi is much better now–so much so his wired network was suddenly struggling to keep up with it.

Vigilante router security

Last week, Symantec discovered a worm that infects routers and takes measures to make them more secure. For lack of anything else to call it, Symantec is calling it malware, and most of the security echo chamber is probably howling over this, but I think I understand why it was created.

DD-WRT needs to be saved, but I won’t bet on it happening

A college classmate asked me if there’s anything to the stories that DD-WRT might potentially get locked out due to new FCC regulations.

Unfortunately the answer is yes, there may be something to it.
