How is Cable Internet Installed?
The process of installing cable Internet is relatively straightforward, but it is more complicated in some situations than it is in others. If a residence is already wired for cable television, then cable Internet is installed by simply connecting and setting up a cable modem. If there is no pre-existing cable connection, then a technician has to hook one up before cable Internet can be installed. One or more cable splitters may be needed as well, and it's also vital to make sure that the signal strength is strong enough to support data transfer.
New Cable Installations
The first step in any cable Internet installation process is to verify that the residence has a working cable connection. In situations where a house isn't already hooked up to the cable television infrastructure, a technician has to start out by making that connection. That is typically accomplished by stringing a coaxial cable from a nearby utility pole.
If a residence is wired for cable internally, then the technician can simply hook up to a pre-existing connection on the exterior of the house. If there isn't any pre-existing exterior cable connection, then he will have to drill through an exterior wall and install a new wall plate inside. After that has been done, the house will be ready for the technician to install cable Internet.
Pre-existing Cable Installations
In situations where there is a pre-existing cable television subscription, cable Internet installation is typically very simple. In these cases, the technician will start by checking the strength of the cable signal. If the signal is weak or poor, then he may have to install a new cable between the house and the nearest utility pole. If the signal strength is sufficient, then he can start by hooking up a cable modem.
The cable modem is the component that allows local computers to communicate with the Internet via the cable connection. This modem should be located as close as possible to a cable outlet in order to provide a good connection. If only one computer will be hooked up to it, then it should also be located close to that computer. In other cases, a wireless router can be used to spread the cable Internet connection throughout the residence.
In some cases, hooking up the cable modem is the final step in the cable Internet installation process. After the modem is hooked up, it will automatically connect to the Internet. In other cases, the modem has to be configured before it will work. This configuration process may involve setting up the modem with the proper account credentials, or it may be performed online the first time that you try to access the Internet.
Do It Yourself Cable Internet Installations
Some cable companies provide the option of mailing a cable Internet installation kit instead of sending out a technician. If your house is wired for cable, and you're comfortable working with technology, then you may want to consider this option. The DIY kit will typically include a cable modem and any other hardware or information that you'll need to get cable Internet up and running at your house.
Since DIY cable installation is only an option if cable television is already available, it tends to be a relatively straightforward process. After you receive your kit, you will need to locate a convenient cable wall outlet. If that outlet is already in use, then you will need to install a splitter. If you are unable to receive a cable Internet signal after hooking up the modem, you may need to connect the modem to a different outlet. The cable Internet signal is strongest at the point where it first enters your house, so you should try to install your modem as close to that as you can.
Coaxial Splitters and Cable Internet Signal Strength
The biggest issue that can come up during cable Internet installation is poor signal strength. That essentially means that the signal from the cable company is too weak for the modem to establish a connection. This will typically manifest as the modem continuously scanning for a signal and never finding one.
If the cable Internet signal is too weak where the cable enters a home, then a technician has to fix the problem. In many cases, he will need to replace the coaxial cable that connects the house to the junction block on the nearest utility pole.
A poor cable Internet signal can also be the result of old wiring inside the house, although signal degradation is often caused by coaxial splitters. Each time a cable signal is passed through a splitter, it grows weaker. That means this type of problem can often be fixed by hooking up the cable modem as close as possible to the point where the cable enters the home. The coaxial connections on old splitters can also become corroded over time. When that happens, installing a new splitter often results in a stronger cable Internet signal.
