I need a help here!

You never really mention what is factoring into the decision, ie is cost an issue, or are you willing to dig a 100m trench, etc.

For performance:

best=fiberoptic

nextbest=buried wires

leastbest=wireless

the order of these can switch depending on what you consider important.

I don't know about trenching permits, but if it's all done on private property then who will know?

Hmm, but i would like to use Wireless network, it's easiest method here, i can't use a cable till my neighbor's house.
How about? what do i have to use?

If you don't use home-made or expensive equipment your range will probably not be good enough. Even if you have a clear line of sight most wireless networks peak in bandwidth around 14 megabits, leaving much to be desired. Range is your real problem

the specs on cat5 say 100 meters, after that, your on your own as to how much further it can go. cat5 standards mandate that it must go 100 meters. its not going to come to a dead stop at the 100 meter mark. i have had cat5 go about 125 meters, results will vary. the only thing to worry about is speed loss from the increased error rate.
