If you have a multimode router, then you would be able to do this.
router
Get 2 USB or Internal wireless receivers and connect both computers wireless to the wireless router
Yes. A router is simply a "distributor" of the connection.
If you don't have a wireless router, that means you can only get connected to the internet using wire / LAN cable.
Not all modems are a combined modem/router. Some companys only supply the modem and if you have more then one networkable device then you can get a separate router yourself.
You can't "share files using a router". You need some kind of network connecting the computers, and a router may be a part of that, but it's not the only part or even the most important part (and you don't technically need a router, specifically, at all).
Yes, you should be able to use the same router software for two different computers. Most current routers will recognize at least two different computers, so the router should be able to take commands from both computers. However, you need to make sure that the actual software is able to be reloaded more than once, because some router softwares only allow one load.
Its not a Router.. they only manage traffic on the network. Servers are specialized COMPUTERS that manage network resources and ALLOW computers access to the network.. BINGO! Sounds like you are talking about a "Router". A router manages and direct traffic on your local network. Routers make your connection faster and easier. It also makes your local network more secure!
No it does not, but you must remember that the printer is only capable of working when it is within a certain range of the router. Like a cordless phone, it can only receive a signal if it is withing range of the main phone connection.
You only need one ethernet connection on the laptop for DSL. If you need to connect to other computers on an ethernet network then you can buy a 4 or 8 port Wireless/Lan router. Plug the Broadband box into the router, laptop into the router. And if you need more connections then you can buy a 4, 8 or 16 port ethernet switch and plug the router into that and then plug the other computers into the switch and there you go.
Yes. There's absolutely no need for a router to download a torrent, since it only has to do with your connection. All a router does is that it connects networks and transfers packet data, allowing you to use your internet simultaneously on several computers with wireless capability.
