A home network commonly uses a broadband router as the gateway device, which the internet service provider usually sets up and maintains. Some users, however, prefer to add a portable network router to their configuration. Also known as a travel router, a portable network router serves as an additional layer of the internet gateway.
It connects a group of devices to the same internet service and shares data among connected devices. Administrators configure travel routers similarly to other types of consumer routers. Configuration mistakes usually underlie internet connection issues. In wireless networking, entering incorrect security keys is a common error. Loose cables or cables plugged into the wrong locations cause problems, too. For example, a broadband modem must be connected to a home router uplink port and not to another router port.
Once you've ruled out configuration errors, subsequent problems tend to be unexpected outages due to weather or technical issues the provider has with their equipment assuming the home network is functioning normally. In some cases, you might have to contact your ISP to resolve connection problems. Most internet access methods rely on a modem.
The modem connects to a physical medium that supports a cable internet CATV line, fiber optic cable, phone line for DSL , or wireless antenna for satellite and wireless broadband services.
In some cases, you can set up two or more internet services on one device or on one home network. For example, a smartphone can connect over Wi-Fi to a home wireless router and can communicate over the cell network instead when Wi-Fi isn't available. These multi-home configurations keep devices connected to the internet with minimal interruption: If one connection method fails, the device uses the other.
An internet connection can be established. However, computers may not be able to reach websites normally if the local network has an incorrect DNS configuration or the DNS provider experiences a service outage. You'll also want to consider the cost of the service, including installation charges and monthly fees. Generally speaking, the faster the connection, the more expensive it will be per month.
Although dial-up has traditionally been the least expensive option, many ISPs have raised dial-up prices to be the same as broadband. This is intended to encourage people to switch to broadband. We do not recommend dial-up Internet unless it's your only option. Once you have your computer, you really don't need much additional hardware to connect to the Internet. The primary piece of hardware you need is a modem.
The type of Internet access you choose will determine the type of modem you need. Dial-up access uses a telephone modem , DSL service uses a DSL modem , cable access uses a cable modem , and satellite service uses a satellite adapter. If your computer includes an Ethernet adapter as many do, connecting your computer to the Internet is as simple as connecting a cable.
However, the setup procedure can become more complicated if you want to network multiple computers at your business together or the Ethernet settings on your computer aren't set to their defaults.
In any case, connecting a new computer to the Internet is a quick procedure that you can complete in minutes. Shut your computer down and disconnect the power cable from the back of your broadband modem. If you have an Ethernet or wireless router, disconnect the power cable from it as well. Connect an Ethernet cable to the back of the broadband modem and to your computer's Ethernet port.
If you're using a router, you'll need a second Ethernet cable. With this type of network, your home has a network router that connects to your ISP. The router is given the IP address for your connection to the Internet and then assigns local IP addresses to each device in your network. These local addresses are often Your IP address is not a When requesting information from a web page, such as Computer Hope, you enter a URL that is easy to understand and remember.
