Linksys WRT54G router and similar are very famous because of great modifications potential hidden in the device. For some purposes you may want to add a serial port to the router. You may need that for development purposes or to turn the router into a robot for instance. This post describes the procedure of taking the router apart so you can get access to the serial port connector hidden inside.
The process is actually described in many places and in various formats. Except for one - video. So I made a video that shows the process. Here it is:

I’m glad this video was useful. I used a WRT54GL as a bridge working under OpenWRT too (before turning it into a robot). It worked flawlessly and way more reliably then the original Linksys OS. Actually DD-WRT seems to be even better OS for this purpose as it has better web interface. Let me suggest getting an _old_ WRT54GS instead of GL as it has twice more memory onboard. Just check the HW revision: newer versions cannot be reflashed at all.
I am not the linux guy but i know a bit of the Progammer in C and other. I found you by accident search from Google and youtube so cool!!!!!
I used to be the robot builder and found this will be my new project. I have WRT54GL and already have DD-WRT, Do I need to re-flash your firmware or just add some of your files in there. I hope it will work for me, I have every part ready to go and Board. this project get my attention for other project that i have in mind for long time/.
Unfortunately the current version is provided as a new firmware only. I plan to release it as a package later, but not sure when exactly.
If you want to try the new firmware right now you can probably try to backup the DD-WRT (Administration->Backup) and make sure you have recorded your key in a safe place. Later you should be able to restore DD-WRT with this information.

OK thanks for this video. I am working with a WAP54G Linksys router and going to buy another one to make an ethernet wireless bridge.

Matteo,
The SSC-32 is not my product. You probably can get all the schematics from the manufacturer: http://www.lynxmotion.com/Product.aspx?productID=395&CategoryID=52.
