Yes, the cable has to be a "cross-over", the subnets need to match, and the IP's need to be within the same subnet.
It's correct, routers do not need to be connect to any computer to work. But if you want to create a network using a router you have to connect computers to it.
A wireless router is usually used to connect internet to your PC without wires but may be used to connect to computers together with the right kind of router.
By using a router with DHCP turned on in the router
They both allow computers to connect without using wires. They use the same frequency.
There are three types of cables used in paired connection of computers: crossover, straight-through, and rollover. Crossover cables are used to connect two devices directly, without a router or switch in between. Straight-through cables are typically used to connect a computer to a router or switch, while rollover cables are typically used to connect a modem to a router or switch.
No, you shouldn't. You should be able to connect to it directly.
It is when 2 computers connect directly with each other. No wireless router between them. When you set up you NIC it will have an option for ad hock mode.
Most computers don't like it so much if you try to connect them together directly with an Ethernet cable. Your best bet is to purchase a router and connect both computers to that. Wait, without cables? If they both have wireless capability, you can create an ad-hoc network between the two. Otherwise, good luck trying to connect them.
A wireless router can be purchased at most, if not all, electronic and office supply stores. It will connect your computer or computers to the internet without having to string (literally) all of your computers together across the house.
router
Connect your printer to one of computers, and share it for all computers in your network. Or if your printer has its own network interface, connect it directly to the router and use it (you might have to configure it for your network settings).
You have to have: 1 home computer that you don't turn off much, a wireless router, and another computer to connect with. Plug in the router to the "server" computer and go to Network and Sharing center. Setup wireless network WITHOUT internet connection. Both computers have to be in the same Workgroup.
