NTP

Are your messages and e-mails being received out of order? The time on your computer may be wrong. By using NTP you won't have this problem anymore.

Bandwidth

If the available bandwidth on your connection is not enough for your needs, its quality will be impaired, and there may be slowness and congestion.

Imagem de capa do vídeo - Jitter

Jitter

Video calls failing? Ever heard of jitter? It measures instability on your network. The higher the jitter, the more unstable the connection.

Imagem de capa do vídeo - Latency

Latency

Is your connection slow? Latency might be the problem, that is, the time it takes for a message to travel back and forth to its destination (round trip). The higher the latency, the worse the Internet quality.

Imagem de capa do vídeo - Loss of packets

Loss of packets

Have you ever been watching a video on the Internet and suddenly the image and/or voice fails? This can happen because of loss of packets during transmission. The greater the loss, the lower the video stream quality.

Imagem de capa do vídeo - DNS - Domain Name System

DNS - Domain Name System

On the Internet, all devices use an IP address (Internet Protocol) to communicate. This is how the information is addressed. But for us, users, memorizing sequences with so many numbers to log into websites would be nearly impossible. That’s why we use domain names, like “cidadaonarede.nic.br”, for example. It’s much easier! But how does it all work? The Internet component in charge of this “translation” work is called the DNS – Domain Name System. It translates domain names into IP addresses.

Wi-Fi signal has a hard time going through walls

Just as your car radio loses signal when entering a tunnel, your Wi-Fi signal can become weaker when it goes through walls and doors. Pay attention when installing a router in your home. Choose a place that improves signal range.

Imagem de capa do vídeo - Electronic devices can interfere with Wi-Fi signal

Electronic devices can interfere with Wi-Fi signal

Wi-Fi uses electromagnetic waves to connect devices to the Internet. Therefore, other electronic equipment can interfere with your Wi-Fi signal! Think carefully about where to place your router.

How to turn your phone into a Wi-Fi router

Is your Internet at home not working? You can use your smartphone as a Wi-Fi router! All you have to do is enable it. Just remember that this consumes mobile data.

Imagem de capa do vídeo - Wired networks are the best connection option

Wired networks are the best connection option

Although practical, Wi-Fi networks can suffer from interference, signal loss, slow connections, and latency, among other problems. Whenever you desire more stable navigation with better response time, a wired connection is preferable.

Imagem de capa do vídeo - Apps and programs consume resources

Apps and programs consume resources

Is your program not working as expected and appears to be slow? It may be because of other programs that are open at the same time. Apps that are running in the background can consume memory and processing power on your computer or smartphone, making other apps slow. Additionally, some apps consume a lot of bandwidth (such as streaming and torrent apps) and can harm other programs that also consume Internet data. Therefore, close all programs and apps that are not being used.

Imagem de capa do vídeo - Wi-Fi channel interference

Wi-Fi channel interference

Did you know that your neighbor's Wi-Fi signal can interfere with the quality of your Internet connection? This can happen if you coincidentally use the same Wi-Fi channel (frequency). Solving an interference problem is simple, just change the channel being used.
