wifi web server that doesn't slow down a robot?

liudr:
This wasn't your first post. Where is the code tag?

To not lock up your robot while doing server stuff, you must rewrite the current code with state machine. I used wifi shield as server a year ago with then latest firmware. The firmware was not stable so I gave up after a lot of tries.

Code tag? Sorry, i don't understand.

Any suggestions on a more stable method to output data via ethernet?
