If you are not happy with your previous provider than you can switch over to a new provider so there are two components to internet ISP services which include the physical network connection to your SOHO or small office and the connection to network services so you can retrieve email or look at a web-site. Most SOHO businesses, no matter how big or small, will have network integration. This is also called a Wide Area Network.
This wide area network connects your computers to the internet. The services that you get out of the network depend on your network configuration. Again, the type of internet service you get should depend on what’s available in your area and how much bandwidth you need for business applications to be run or developing server side applications for your hosting account.
Many people rely on their own mail server or Web-site on their network, while many other business owners rely on their outside hosting providers. You should also look at the types of access that you want.
This way you can switch over to a new host or ISP.
