I managed to lock myself out of my router. I think it must the firewall rules I changed. I can now only connect to it via serial terminal. On the website it says I need a 3,3v ttl serial cable. According to the tutorial it's self powered so I only need txd,rxd and gnd. Is it possible to use my ft232rl breakout from my arduino?
I was thinking of feeding the ft232rl 3.3v on vcc and vccio. Then rxd and txd should equal to 3.3v when driven high yes? The voltage am measuring out of the breadboard psu is 3.68 but that doesn't matter does it? I don't have anything else that outputs close to 3.3v.
Here's a picture of what I need
Picture of how it need to be connected to my router http://www.myopenrouter.com/article/19840/How-to-Debrick-Your-NETGEAR-WNR3500L-Using-Ubuntu-10.04-Lucid-Lynx/?textpage=2
This is how I intend to wire it. Oviously with txd,rxd and gnd connected to the router.
