Any problem like this should be approached by testing step by step, so:
Can other laptops connect to the router? If not then, it may be the router or the connection to the ISP.
Can you connect with a network cable? If that works, then there is a problem with the WiFi - the configuration may be wrong, the connection may be too weak, it may be turned off in the laptop or the router. It may actually be broken in the laptop or router.
A laptop is a PC. You don't need a desktop PC to configure a router, you can use a laptop to do so, by connecting to the router via a network adaptater - either via wifi or ethernet. Both ways of connecting are included on laptops nowadays.
Do you mean that you are connecting your laptop through a router with your main computer in your home? If so, no there is no additional charge to connect.
if you're connecting to other people's network. no you don't
The main equipment you need to set up laptop wireless internet access is a functioning wireless adapter and a router connecting to the internet. You also need to be in signal range of the router.
Strictly NO, but in effect YES. Connecting to wifi means connecting to a wireless router - IF the router is connected to the Internet (it does not have to be), then connecting to it will also give you a an Internet connection.
To connect to the internet via wifi you will need: A wifi enabled laptop/pc OR a wifi card/adapter. A wifi router/network with the internet connection connected to it. As long as your router is set-up correctly and your laptop is fairly new you shouldn't have any trouble connecting to the internet.
If you have a router (connected to internet), and you get a laptop with wireless enabled you do not need anything else. You can connect your laptop to the router and have internet on your laptop.
Connecting different networks requires a router
When you say "connect it to the wall jack", you have DSL connection or cable connection? Does cable connection allow the use use of a wireless router and card
The Linksys Dual-band Wireless A+g Notebook/laptop Router is good.
Is there a router that you can plug a laptop modem into so that I can get internet on my desktop also. The desktop would need ethernet and of course the laptop is usb. So is there a router out there that can do this?
If the access point has a wireless interface and if your laptop supports the wireless network type, no you do not need a router. <><><><><> If the laptop is not near enough to an access point, it will not be able to connect. The router is immaterial.
