And this also explains why sometimes your Wi-Fi signal is at full strength, yet you still can't access the internet. Generally known as the wide area network WAN , the internet connects computers from around the world. In reality, the internet actually connects many local networks together, via a ton of routers. With the internet, your home local network is no longer secluded but becomes part of one giant worldwide network.
The internet connection is generally beyond the control of the users. Other than turning it on or off, the only other thing you can do is pay for the desired connection speed and hope you get what you pay for. Internet speed has progressively increased in the last decade.
Ten years ago, a fast residential broadband connection generally capped somewhere between 1. That said, most of the time, the speed of the internet is still slower than that of a wired local network, which is either Mbps or 1,Mbps. For a Wi-Fi network, the speed of the local network depends on the standards used by the Wi-Fi router or access point and the connected clients, and can sometimes be slower than a fast broadband wired internet connection.
Just because you have Wi-Fi doesn't necessarily mean you have internet access. Also, having a strong Wi-Fi signal doesn't always translate into fast internet speed. In fact, to know how fast your internet speed is, in most cases, you need to test it independently from Wi-Fi. That said, keep in mind that if you use Wi-Fi to share the internet, then it's the internet speed that you want. In this case, Wi-Fi is just the vehicle that carries internet to your device.
This means if all you care about is a full Wi-Fi signal, then you're missing the point. Take Wi-Fi extenders, for example. These devices wirelessly extend the coverage of an existing Wi-Fi network. Each time the Wi-Fi signal is extended, there's a 50 percent signal loss. This means if you have a few Wi-Fi extenders, by the time the signal gets to the device you're using, there's not much "internet" left for a fast, stable connection.
The best way to extend your Wi-Fi network is use multiple access points that connect to the main routers via network cables. If running cables is not an option, then be sure to have no more than one Wi-Fi extender in a network. Most importantly, when you're connected to an unknown Wi-Fi network such as one you see popping up on your phone or laptop when you travel , keep in mind that because you need to access their router to get on the internet, the owner of that Wi-Fi network can potentially see all the information you're sending and receiving, including usernames and passwords.
That said, when using free Wi-Fi, unless you're accessing a secure website one in which the address, or url starts with https don't type in any sensitive information.
Better yet, refrain from doing any online banking using free Wi-Fi. Also keep in mind that public Wi-Fi from known entities, such as an airport or an office, is generally more secure than a Wi-Fi network at a random cafe.
An open Wi-Fi network, one that requires no password or agreement of terms of service to use, is the most risky.
Wired internet aka residential broadband : This is when you connect to the internet using a physical cable, be it a telephone line DSL or a cable line cable , or a fiber optic line FIOS. This type of internet connection is fast especially cable and FIOS , affordable, and is the most popular. A wired internet connection generally comes with no data caps or at least very high caps, so users don't need to worry about how much they download or upload.
Satellite internet aka satellite broadband : This is similar to the wired internet but instead of connecting to the service provide via a cable, the home network connects to a satellite dish on the roof.
The dish then communicates with satellites to provide the internet access. Satellite internet tends to be slightly more expensive and slightly slower than wired internet but is still an affordable option for remote areas with no cable, DSL or FIOS services.
Wi-Fi on the other hand, is considered more of a type of radio signal that allows devices to connect to each other wirelessly, to be able to transfer data. Generally, a Wi-Fi network is made possible through a router, which then allows all devices connected to the network to share data and participate in other local activities that require no internet connection.
Where Wi-Fi connects devices locally, the internet connects devices from around the world. Simply put, the internet connects networks together using millions of routers. What to read next Read more.
