Hi to all developers
In my case, I have Arduino UNO + Wiz 5100 shield (ethernet shield) connected with LAN cable to external Linksys 5 port workgroup switch (EZXS55W model).
At the first time when I power on the Arduino I can ping the Arduino from my PC but.. If I change the LAN cable to other switch port then I can't ping Arduino anymore (even if I power on and off the arduino module)..
Is there a solution for this case?
