I read about this open source wireless router software, DD-WRT, and decided to give it a try. I bought a $12 router on eBay, flashed it and started messing around. There's something quirky about the way I have out home network that's stopping me from using it to repeat signal to the back yard. Last night at a gig though I had a few minutes and finally it it going.
I stuck it in a window and got it connected to the neighbor's open network and suddenly, voilà! I had my own secure network right there in the bar. I got my laptop and iPod connected and was running iTunes remotely during set breaks. I even got the wireless mouse app to work so I could run the recording software and browse the web without reaching in front of the lighting guy
Anyway, it felt hella good to be tinkering again.
