hi i write a program but i get error because if i connect any peripherals form ic2 with network cable it won't connect it doesn't write peripheral reactor_0 connected or someting like that between computers that work please help

Ok, first of all, please write out your question in a human-readable format. We're not in grade school anymore. Use your big-boy words.
Second, please post your code. We aren't psychic, and can't magically understand where your error is.
Last, please post the exact error that you're getting. Unless we know the error, we can't help you.

ok first i am sorry i am slovenian and i don't know english very good there is not mistake in program but in network connection if i press on network modem it doesnot become red (on reactor, on computer it does) and now i don't know how to fix that

ooh, I'm good at rewriting stuff!

"Hi, I wrote a program that uses ic2 peripherals, however it errors because I don't have the peripheral name. When I attempt to connect peripherals with networking cable, it won't connect and it doesn't write the peripheral name in chat. Please help."

If I am interpreting this correctly, you might want to check that the peripherals are actually supported in the versions you are using.

i am using 1.63 cc and tried with every combination in ic2 (for 1.6.4)

All right, I retract my first statement then. Sometimes it's hard to guess if someone's not a native english speaker or they're just a lazy english speaker. I guessed wrong.

EDIT: Back to the issue at hand, since CC doesn't natively support IC2, did you install OpenPeripheral? If not, you won't be able to communicate with IC2 as peripherals.
