Installing dd-wrt on a Linksys WRT160N-RM v.3

Tuesday, December 8th, 2009

So I cheaped out and bought a refurbished Linksys WRT160N from Amazon for $28. Great price for a 802.11n enabled router (most are in the $100 range) but it kept dropping wifi connections, slowing up and refusing to respond. Wired connections were fine so I suspected a dodgy radio. Linksys support couldn’t fix the wifi issues so I was about to send it back when I decided to wipe the Linksys firmware and flash dd-wrt to it. The router wasn’t doing much anyhow.

The latest version of dd-wrt supports the WRT160N v.3 router. It is easy to install via the router’s web admin interface and rather than repeat myself here I’ve updated the dd-wrt community wiki page with the step-by-step instructions.

Note: when you search the dd-wrt router database it’ll give you back three different bin files to choose from. You only need one of those to kick off: dd-wrt.v24-13309_NEWD-2_K2.6_mini_wrt160nv3.bin AKA “mini” is the basic dd-wrt firmware that I used. It has more than enough features to keep most users happy.

My router has been up and running with dd-wrt for the last 4h29m without any problems and it feels faster (not sure if that is psychological). The best part is that the nerd in me is now super excited to have a working, fully featured, Linux-based router in the office.

Construct at University of Colorado at Boulder

Monday, December 7th, 2009

I’ve been talking with faculty staff at CU CSCI about the kind of work they’re doing and to see if there is any projects that we might collaborate on. After a chat with Katie Siek we decided that the most efficient way to introduce my research from UCD and Glasgow was to drop by and give a presentation.

For the opening I talked a little about the data binding technologies we developed at Strathclyde. These “type projection” systems provide a safe and extremely efficient mechanism for computing over semistructured data sources (if you’ve ever used JAXB from Sun they’re kind of similar). I skipped pretty quickly over that, hopefully didn’t loose too many listeners, and jumped into Construct.

Construct is our open-source community platform for Pervasive Computing. It is a middleware that provides the plumbing for developers of Pervasive or Ubiquitous systems. Rather than spend time writing code for management of services and data flow across the network developers can concentrate on the problem domain for their specific project.

I was invited back to talk with Ric Han’s group early January.
