Is there a way to update Arduino uno Over The Air I have the Arduino uno with a Ethernet W5100 Shield and would like to remotely sketches.  Is there a way to update Arduino uno over the air?  If not, is there a wired network arduino solution that will allow update over the air.

I've done this on the esp8266 using there tools but I can't find one for the Uno.

Thanks
Not with WiFi, nor with Ethernet. People have managed it with Bluetooth, but only because it can create a transparent serial bridge. The bootloader only talks serial, so you have to use something that is serial to program it.

The only possible way is to use another WiFi (or Ethernet) device, such as the ESP8266, to act as a serial bridge to connect the Arduino's serial port (and reset signal) to your computer over WiFi. A bit of a waste of an ESP8266 since that is then the sole task it would have (unless you craft a far more complex sketch for the ESP8266 to allow it to do other things as well).
