I would like to know what WIFI board you guys would use for your first project.....I need something that works :). I have the Arduino wired server working fine and would like to move to wireless. I have this board:
It looks like a nice board however there is no support and after hours of playing with it, I can only manage to receive serial data from it at a different baud rate than what the online manual states. I can not talk to the board as stated in the documentation.
So is there a wireless ethernet board out there that works with the Arduino Mega board without having to spend hours on it?
You could take a look at the Adafruit WINC1500 WiFi Shield for Arduino or other shields with the ATWINC1500 module. That is the technology used on the retired Arduino WiFi 101 shield and the active Arduino MKR1000. This makes me think it's a reasonably good option, but I have no experience with its use on a shield.
It's certainly possible to get the shield you have now working. If you use the search terms doit esp8266 shield you should find quite a bit of information. I have one of these shields and it came from Doit with some weird proprietary firmware on the ESP8266. I preferred to replace that with the standard AT firmware, for which there is a lot more official and community documentation. There were reports of people getting the same shield from other sources with the AT firmware instead of the Doit firmware. The two firmwares are very different so you should be able to easily determine which is on your shield.
