i got a switch and 2 pc and a dsl modem
is it possible to both of them can have a internet connection at the same time
how???
Maybe, if the DSL modem has a built in Router just plug the PC's into the switch and the switch into the Modem. If it doesn't have a router then each PC is going to get a Public IP instead of a Private IP address. Most ISP's will only allow you to have one public IP so only one PC will connect. The only way to find out is to plug everything in and see if both PC's get a connection. If only one PC works you'll have to but a router, use Internet connection sharing, or pay extra for another Public IP from your ISP.
wow this answer is perfect completely understandable not geeky answers thnks men so..
thats why last few years my old modem is connected to my switch and it can have internet at the same time, but they replaced my modem so it is not built in with router(
so i should buy a router to have internet at same time right???
So, right now, only one PC can get Internet? If yes, swapping out your switch for a router will let you connect more than one PC to your Modem and let them all get Internet access.
If you open a command prompt, (start menu > all programs > accessories > command prompt) and run ipconfig/all. That will show you if your PC is getting a private IP like 192.168.0.X or a public IP like 24.222.0.X. Those are just examples. A private IP means you are going though a Router, a Public IP means its a straight connection to your modem.
