The two computers are connected through a LAN, with normal wired connection using a switch of course, and having an internet feed from normal speedtouch router. addressing and subnet masks are correctly setup. subnet mask 255.255.255.0 router = 10.0.0.138 and the other two computers = 10.0.0.1 and 10.0.0.2 very simple home network... but I don't know why it doesn't go well????
