A modem is what receives your internet signal from your ISP and a router is used to split that signal either by wired or wireless means.
The router basically controls communication within your network (the "routes" of information). Most home routers have 4 ports to hook up network cables and also a wireless component in addition (but not always!). A wireless router is what you are looking for.
the router gets plugged into the modem (whether your DSL, cable or wherever you get internet from). A few (like my Netgear DGN3300) have a modem built in and i plug it directly into the phone line. but this is no very common.
I think if you only have one wireless laptop a simple wireless access point might work. But good routers are not that expensive and you also get more security, guest networks etc.
Depending on what type of internet connection you have, and who it is through, you may be able to get what they are calling a Wireless Gateway. The ISP's usually have a model they will provide to their customers who need a wired and a wireless connection. The important part about using a device from your ISP is they will support it if you have any trouble with it. If you are feeling a little bit more adventurous, you can buy your own Wireless Router to go along with your modem. Either way will give your laptop wireless connectivity.
that means , the black device i use and connect the ISP wire in the back of it provided the electrical connection to establish a wireless connection is know as a router and not a modem . is it ?
in ur idea , the router just splittes ? it doesn't receive ? also the modem , it only recieves ? it doesn't split ?
i know i have only one device , not two
Could you please look at the device you have and post its name? should be written on a label on its underside/backside. Helps us give better directions on what to do.
There are quite a few modem-routers with Wifi, that is a modem AND a router with wifi in the same box. They aren't that expensive, but if you have a modem already (the DSL provider gave you that I think?), it should have 2 ports (plus the power adaptor one), one that is for the DSL line (the thing from the wall socket that is NOT power), and one that is for the ethernet cable (the cable you use to connect it to a computer/computer network).
If you link the latter to a router (they have a ethernet port clearly labeled "modem" on their back), the router will do its job of allowing all devices connected to it to use the same modem, plus the features routers have like firewalls and whatnot.
IF the router has wifi, it will allow wifi devices to work on the net.
If you have already a modem-router without wifi capability, you need yet another device called wireless access point, that connects to the router/modem and creates the wifi network with its antennas. These devices are usually also routers, so they can connect to a modem just fine.
As I said above, please tell what is the device you currently have, and we can tell exactly what you need to buy/do.
Yes on the connection and No on the wireless (that's a separate piece of hardware)...the piece of hardware you have should be the modem from your ISP. It is a wired connection (cat5e cable) from your modem to your PC. If you want to split that signal you will need a wired/wireless router (I prefer Linksys). With that you'll have an installation cd/dvd with instructions on how to setup and hookup the wired/wireless router to your system. Very easy to do.
from bobafetthotmail post can i say that there several pieces of h/w as follows :
1/ modems
*has 3 type of ports .. RJ45 ,RJ11 and power
*can be used through ethernet cables , not wirelessly
*only accepts one PC
*if a router is connected , it accepts many PCs through cables
2/routers
*not responsible for any net providing , only for distributing
3/modem-routers with wifi
integrated piece allows more PCs through ethernet wire
4/modem- routers without wifi
integerated piece allows PCs through cable and wireless
