工作学习 / 科技领域杂谈 / 问一个关于 wireless internet 的蠢问题。如果我现在用 cable modern + hub 连两台电脑，因为我自己有两个ip。如果我想改成 wireless 的，是不是要直接把 cable modern 连到 wireless router 就行了？总觉得好像漏了什么，是不是应该问问 provider 我这个帐号有没有提供 wireless gateway 之类的？

Yes. Cable modem --> wireless router --> your computer via wired ethernet as well as you computers (laptops probably) via wireless ethernet.wireless router has NAT gateway built in. So just one (external) IP address would do. One of the two you have right now will do. You do not need to ask your cable Internet ISP. All computers connected to the wireless router (either via wired ethernet ports or wireless) all use an "internal" IP address space. Just go ahead, buy a wireless router, and feel and enjoy the freedom!

What's a NIC router? A normal (non-wireless) router? Wireless router normally has 4 ports. Do you have more than 4 computers that you want wired connection?

I meant a normal (non-wireless) router. Ok. I have 2 very old computers with NIC cards connecting normal router. Now, I want to buy a wireless router for my laptop and join the 2 old computers. How? thanks

这都哪跟哪，现在普通的家用wireless router都带4个有线(NIC)网口，可以同时接无线网络和有线网络，而且都有DHCP，可以让你的计算机获得内部IP。没什么好担心的，一跟线接modem，两根线接旧电脑，无线直接接。很困难吗？
