Note - Combined services generally offer discount pricing and may include amodem/wireless router.

If you use a wireless router with the DSL or Cable Internet service and yourlaptop has a wireless card then you can also connect to the Internet at WiFihot spots like McDonalds, Star Bucks, the Airport etc.
If you use the wireless 3G wireless broadband service, then you can access theInternet anywhere where your ISP has 3G wireless coverage. You need to checkthe service coverage area where you need Internet service.
Once you decide what type of broadband your require, then you need to checkwith the various Internet Service providers to see if they can offer and thecost of the various plans.
Note the download limits and the associated additional costs if you exceed themonthly download limits. Once you sign up with a Internet Service provider,their documentation will include setting up instructions and/or installationCD.If you have a wireless router and it is connected to the DSLor cable modem and Internet then -To connect to your wireless router, the router needsits wireless settings to be configured with the SSID, encryption key etc., alsothe wireless cards and wireless adapters in all the laptops/computers needs tobe configured with these router's wireless settings.
