How Does a Wireless Network Work?

Back in the day when we only had cable Internet, do you remember how inconvenient it was? You had to choose a fixed position for your PC or at least a position that your cable could reach. Mobile data was slow and so expensive because they had no competition. Then everything changed when wi-fi became popular. More people buy laptops because they can carry it anywhere and still be able to connect the Internet, with no cable required. Mobile data became cheaper because then people had options.

How Do Wireless Networks Work

When you set up a wireless network in your home, you are required to have a router. This router acts as the key signal transmitter and broadcaster for network data. A wireless router uses radio signals instead of cables to transmit data. Your router is capable of transmitting data within a certain distance, normally within 90 meters from the router itself. This distance is an estimate which varies depending on the material and depth of your walls as well as the presence of other electronic devices around the router.

The wireless router practically creates a hotspot where all devices within the network can connect to the Internet. To be able to connect to a wireless network, usually, you need a wireless card installed. Most modern laptops are equipped with a built-in wireless card that doesn’t need any additional configuration. For older desktops, you may need to purchase a separate wireless card or wireless USB to be able to connect. These wi-fi USBs are not expensive, with the cheapest one costing only about $10 each.

Weak Signal Troubleshooting

If your wifi network appears to be weak and your computer keeps dropping the connection frequently, it’s time to think about the possible causes of the problem. First, try restarting the router to see if it solves the problem. If the problem persists, consider moving your laptop closer to the router. Normally this alone helps solve the problem.

However, if for some reason you cannot maintain your laptop close to the router all the time, and moving it away affects the signal, there are still solutions. The first solution is to ask your service provider to move the router to a more convenient place for you. Your service provider may need to prolong the cable so that the router can be moved to another room.

If your home is a bit on the big side and you would like to be able to access the Internet no matter where within the house, consider buying a wifi signal extender. A wifi signal extender will act as a second access point that receives the signal from your original router and amplifies it. The wifi extender will create a second virtual network, with the same settings as your original network, including the password. The second network will offer stronger wifi signal and your devices will not have any problem connecting to it.

Above are some basic information regarding your wireless network. To secure your network, make sure to use a strong password consisting of numbers, special characters as well as capitalized letters. Don’t choose a password that is too easy to guess or a word that can be found in a dictionary. Having a strong password will protect you from potential hackers that can happen to pass by or even live near you.
