If the AIR light is not turning on, the router is not connecting to your wireless network (as you correctly deduced). Your config files look correct. It's probably an issue with the wireless channel or the WEP key. Verify the channel is set to the same channel your wireless network is using, in this...

The switching power supply on the router is, if I remember correctly, for the 3.3V rail that supplies power to the CPU and most of the other digital ICs on the board. The 5V wall wart that comes with the router provides regulated 5V power for the USB port. There could be other things on the 5V rail ...

I'm confused as to how you got tftp to work without being able to ping the router. If tftp works, then the network connection to the router is obviously working.

In hardware, you can play with series resistors and capacitors to ground on the switch lines. There are some examples in this document I found, google will turn up lots of other suggestions: http://www.ganssle.com/debouncing.pdf In software, the easiest way would be to alter your code to detect the ...

Another subtle problem you can run into: If your home wireless network uses the 192.168.24.1 subnet, your computer may not be able to talk to the router because it sits on the same IP address as your home wireless gateway (192.168.1.1). A quick workaround is to disable your computer's wireless inter...

Since my original post, I have found that TechSpray G3 series flux remover works really well, but will melt some plastics. It is truly nasty stuff, I wear gloves and goggles when using it.

Yeah, that is a good place to get 5V, that pin comes right off the wall wart which is a nice regulated 5V source.

The serial enabled 3.3V LCD *should* work, but I have never used one before so I can't say for sure!

Any idea what format the mass storage device on the device is? You may need to install the corresponding fs kernel module, ie. kmod-fs-vfat, or kmod-fs-ext3, etc.

If you mean the WL-520gC (not 530) then yes, these two routers appear to share the same base hardware. There should be some notes on the PCB about which components are different between the two versions of the router. There's a slide about this with some pictures in my NOTACON talk (page 26 of the p...

Originally, I wanted to gut an old AM/FM table radio and stick the WL520gU inside. I still think this would be really cool to do - you could even stick the LCD behind the tuning dial and repurpose the tuning knob to control a potentiometer.
