10 harmful misconceptions about WiFi routers that many people make

As we know, the technology world is developing rapidly, wifi signals cover almost the globe, and wifi routers are becoming more and more popular in our lives. There are many issues surrounding this. Most of us, when buying a wifi router, either use it directly, or just set it up superficially and then use it, while holding some beliefs that are thought to be always true? So, is that really the case when the methods of hackers as well as wifi routers are becoming more sophisticated. The following article will delve into analyzing these harmful misconceptions about home wifi routers Harmful myths about your home wifi router 1. Nobody wants to attack my network There are two very common views today: Hackers only attack large centers, companies, banks, or celebrities, while unknown people like me have nothing to gain from hacking. Small networks, with fewer security vulnerabilities and less valuable outcomes, will not attract any attention for hacking. The first thing I want to say is that these two views are completely wrong today. In the past, perhaps that was partially true because wifi networks had a small coverage area, making it difficult for hackers to attack from a location outside the coverage range. But nowadays, there are many devices with high-power antennas that can detect your wifi from a greater distance than you might expect. "No one hacks your network because they won't gain much?" You will have to change this thinking immediately after reading this article. Because according to the CEO of Avast Antivirus , Vince Steckler, once stated: " The security vulnerabilities of wifi routers are being discovered more and more, while hacker tactics are becoming more sophisticated. On the other hand, as most of users' important information is currently stored on computers, this creates opportunities for hackers to attack" Therefore, if you do not secure it carefully, one day your bank account may disappear without a trace. What's worse is that hackers can impersonate you to do even worse things, such as: buying houses, taking out loans from banks... using your personal information. 2.

Điều tệ hại hơn đó chính là các hacker có thể mạo danh bạn làm những điều tồi tệ hơn đó chính là: mua nhà, vay ngân hàng… dưới thông tin cá nhân của bạn.

2. Dual-band routers are unnecessary

It is recommended to use routers with 2 to 3 bands

Many people think using a dual-band Wi-Fi router is unnecessary, and a single band is enough. However, most of our usage needs require using both bands. For example, using a smart TV and computer on one band, and smartphones, tablets, and Kindles on another band will make your internet connection more stable and organized.

3. The 2.4GHz frequency band is better than 5GHz

This opinion might be true, but in some cases where too many devices are accessing the network on the 2.4GHz band, it leads to a slower and more unstable network. In this situation, switching to the 5GHz band will be more optimal. Meanwhile, the 2.4GHz band has a wider coverage area and better penetration through objects like walls and concrete than 5GHz. When you feel your internet is suddenly slow, try switching to the 5GHz band. But if you are browsing the web from a farther distance, use the 2.4GHz band.

4. Do not change router configurations once they are set up by experts

This happens when parents don't allow you to mess with the Wi-Fi router after it has been set up by experts. In reality, learning and changing some basic settings to suit your environment and living conditions is advisable, of course, you should not tamper with the device's hardware. If you own a new router, switching from standard N to AC will bring significant improvements in network speed and stability. Another important thing is to change the security mode from WEP to WPA2 with AES for better security. And changing the default username and password is a must.

5. Hiding the SSID will make it undetectable and thus avoid hacker attacks

This might prevent snooping and Wi-Fi theft from neighbors, but for hackers, finding the SSID is as easy as pie, and it might even make it easier for them to hack. In reality, when you hide the SSID, devices tend to automatically connect when within range. Hackers can exploit this by setting up a Wi-Fi network similar to yours, and when your mobile devices automatically connect to that network, it opens the door for hackers to attack those devices.

6. Why upgrade the router if it's still working fine

Every few years, new Wi-Fi devices with advanced technologies are released to keep up with internet speeds. For example, standard N only supports a maximum data transfer speed of 50Mbps, but if your network exceeds 50Mbps, you won't be able to optimize your network's capabilities. Therefore, you should switch to newer routers with designsAC standard. Although it is not necessary for people with normal usage needs, it is for those who require high-speed network usage.

7. WEP security is safe at home

With current advanced technology, WEPsecurity is considered as you are not using a security password, because with a simple hacking software, it can access your network as easily as pie. Therefore, you don't need hackers; your neighbors can also "steal"stealyour wifi easily.

8. Using WPA2 -AES security is absolutely safe

Currently, no one has been able to break this security technology. It is estimated that to break this security, you would need 1 billion years using a brute-force algorithm. However, the level of security also depends on the user, because careless people often set very simple wifi passwords like "abcdefgh" or "123456789"... which are very easy to guess. A strong password should typically be more than 8 characters long and include uppercase letters, lowercase letters, and numbers.

9. Using WPA2-AES security will reduce transmission speed

This would be true if you haven't changed the settings to be compatible with WPA-AES security. Usually, manufacturers will design functions to adapt to WPA-AES security so as not to affect the network transmission. If you are using older wifi devices, you may need to upgrade the firmware to be compatible with AES encryption.

10. Network security is unnecessary when you have a firewall and antivirus software

It should be understood that firewalls and antivirus software only protect you from malware on the network when you download data, which can steal your data... However, neither can protect your computer when it connects to wifi access points. Above is a summary of 10 very common misconceptions at the moment. We hope this article will help you avoid the dangers from hackers and other malicious actors.
