Upon the Subject of Routers – DD-WRT

An optional assignment for IT 566 is to install DD-WRT. DD-WRT is an open source firmware replacement for the stock firmware that comes on routers and other devices with embedded systems, in my case a Linksys WRT54GL. A screenshot of what the stock firmware looks like can be seen in my previous post.

Many moons ago I was a computer technician, and I still tinker with hardware occasionally, I just don’t get paid for it. I’m more networks, system administration, and web development these days. One really important thing I’ve learned over the years is that unless there is a problem with the hardware or you need some new feature, don’t mess with firmware. You can quite easily turn a device into a nice paperweight, which may or may not weigh as much as an actual brick.

The DD-WRT site warns you many times that you could brick your router. I printed out and read the DD_WRT documentation for the Linksys WRT54GL very thoroughly. One caveat with the WRT54GL is that you can’t install the full version of DD-WRT to start with. You have to install the micro or mini build first and then install the standard build after that. The process can be time consuming and you can’t rush or skip steps, unless you want a brick.

But at the end of the process you have a working router again, which may have more/easier to access features than with your old firmware. Here’s a screenshot of my WRT54GL running the standard build of DD-WRT. I erased a lot of things from the screenshot, like IP and MAC addresses and my SSID.

Upon the Subject of Routers

One of the assigments for IT 566 is to get a router. Luckily I’m using a router right now, a Linksys WRT54GL, so this one was simple. Here’s a screenshot of the router admin to prove it exists. For others in the class who might need help taking a screenshot I used an extension for Firefox called Screengrab.

Aside from being an archive of Twitter posts my blog was pretty dormant for 2009 and 2010. But I’m taking a class in Instructional Technology at UTK (thank you UT staff fee waiver) IT 566 that’s being taught online almost exclusively through blogs and Twitter.

So there’s a new category for the class and an associated RSS feed for those that want to follow along.

Sometime I’ll probably put a fresh coat of paint on here. The design I’m currently using is a custom WordPress theme I designed in January 2006. After five years it could use an update.
