Apologies first if I've asked this in the wrong part of the forum. I wasn't 100% certain but I think this was the most suitable area.
Hi all, I've just recently got my first arduino and have had a bit of a play so far successfully with LEDs, servo control, and a 1602 LCD display - so far so good.
Yesterday I got a linksprite copperhead v2 wifi shield so I tried to test it last night on my uno board but no luck really getting it to do anything yet.
The best I've achieved so far was with a network scan example sketch where I could see on the serial monitor that it said it first initialised, then was scanning for networks, but did not return any results at all. Not sure why when my wifi is very strong and it was in close proximity to the router.
Sometimes when I tried to run the sketch, it would stop at initialising stage, or not even come up with that.
What would be the most absolute basic code I could try in order to ascertain if this shield is working correctly, or to verify some basic wifi 'presence' etc?
Sorry if I haven't described it well. I realise the examples are a basic starting point of course, so it's embarassing to ask, but I'm wondering what I might be doing wrong.
These are just a case of plug onto the arduino, then verify/upload the code (depending on any code changes needed) right? Or is there some other thing I have to do with the hardware itself before it runs correctly?
Trying again tonight and still nothing happening with the examples from the wifi library.
My uno is a v1 version from what I can tell. I know that some shields need a jumper when using older than v3 uno, but I can't tell if the copperhead is one like this (ie where 3.3v must be connected to another pin?). Any ideas?
I have also tried powering the uno via external 12v psu after finding a google search result on here where someone else had the same error "wifi shield not present" and solved it by powering the uno externally like this. No joy though.
So all I can get using any wifi examples I try currently (with or without external power, and via a couple of different USB sockets) is the error above re' shield not present.
Suggestions for why it's not found would be gratefully received - thanks!
What "WiFi" library exactly are you using ?
The LinkSprite CuHead is a clone/copy of the WiShield from AsyncLabs. AsyncLabs closed their doors but the library can still be loaded down from their site.

Hi Jim,
Did you manage to solve your problem? Does your wifi cuhead shield work now? What was wrong and how did you solve it?
I also have a similar problem... I have an Arduino Uno R3 with CuHead V2 Wifi Shield, uploaded example sketches but doesn't work.
