回复：怎样才能让两台电脑都上网,用网线可以吗?

If both of two PCs have Ethnet card, you can connect them with a crossover cable which is looks just like a regular cable, but "crossover" some port. Then you connect one computer to the internet and another PC can connect to internet throught the first PC. The more detail information could be found by google. Good luck!
