ARDUINO SOLAR METER V 11.41 disconnect from internet

May 29, 2015 at 10:02 PM
Good morning , I recently installed the software ARDUINO SOLAR METER V 11.41 on a board Arduino UNO r3 ( original ) with W5100 ethernet card. After setting up the profile PVOutput and the data appear correctly on the PC. After a few hours I noticed that Arduino was disconnected . Checked the sketch , recompiled and reloaded the software , everything went well for half a day , then again disconnect .... Restarting Arduino , all right .... another time and again .......
Can someone help me ?? I'm inexperienced and do not know what to do !

thanks
