If you work at home a lot or have a ton of computers for every member of the family than it would help to have a wireless router. These will give you the ability to connect each computer in the home directly to the internet. You can even use it to print out documents from anywhere in your home without being directly linked to the printer.
When installing the router you need to be careful with how you do it. First you need to choose a model that is going to work well in your home. How many computer will you be connecting and how strong do you want it to be? Compare the various models on the market and make sure to get something that meets your specifications.
During the installation process you will need to hook it up directly to the modem. Use the right Ethernet cable that is going to give you a strong connection. Once all of the lights are on you can move to connecting your computers to the router. For extra measures you should test out the Internet connection to see how well it is running and if it really does work.
The only way that you are going to be able to do this is if each desktop or laptop has a wireless card. If not than you need to buy it and have it installed. This can be tricky so have a professional do it for you.
Once that is done you will follow the prompts to connecting your computer. This is not a difficult process to have done. Make sure that during the wireless router installation you set up the necessary security measures. This will keep people around you from trying to connect through your machine and slowing the connection down.
