Is this normal?

[EricVanWyk]

I need a few more pieces of information:

What are the adaptors LEDs doing when it is not working?

What is the voltage it is getting when it is not working?

Next time it stops working, record those and post. Then, pull the plug out of the adapter and plug it back in. Wait ~15 seconds. Does it work?

If it does, it is a problem with your adapter. I alerted Linksys to a problem a few months ago. If the power glitches OR takes too long to ramp up, it will hang indefinitely.

I spent a long time characterizing this, and I've only managed to get it to happen by

• using an unregulated battery connection
• "fuzzing" the supply down below 3V.
• unplugging and replugging the connector very quickly
• ramping the voltage very slowly.

Basically, one of their processors hangs, and there is no watchdog to reboot it (ALWAYS USE A WATCHDOG). So, if you ever have a power glitch at home and your Linksys product goes out to lunch, blame the lack of a watchdog.


Vikes - Thanks for the faith

Akash - The cRIO and the WiFi are the last to die. Motor control is cut several volts before the logic system dies.
