How to troubleshoot your WiFi network (Part II)

troubleshoot your WiFi network

Now WiFi is everywhere and is embedded in every device. This technology somehow plays the role of oxygen for Internet access, media streaming, gaming and any kind of networking work. So it should always work well, and if not, you will get in big trouble. In this article, which is divided into two parts, we will discuss a number of common causes and factors that cause Wi-Fi problems and how to solve them.

In the first part of this article, we got acquainted with the technical terms related to Wi-Fi networks and discussed three common causes and factors that cause Wi-Fi problems and how to solve them. In the following, we will examine the other problematic factors.

Your network connections are unstable

There are four main factors that cause instability in Wi-Fi performance and network access: an irregular broadband (Internet) connection, distance from the central station (router), incorrect choice of central station, and a crowded local area network environment. .

  • Broadband. The first test is difficult unless you can connect an Ethernet cable to the router and use a bandwidth tester like Ookla or a network monitor that shows your performance over time.
  • Space. In appearance, the solution seems simple: reduce the distance. But if you do not know where the Wi-Fi transmitter station is or if you are in a room away from the router, shortening the distance will not be easy. Due to the reflection and absorption of the signal, it is best to always place the central signal propagation station (router) in a place that achieves the best coverage area. The NetSpot app   can help you find areas covered by waves and map areas with the most signal strength. There is also a free version of Ekehau’s Heatmapper app that offers the same feature.
  • Wrong Central Station. It does not matter if you are in a 10,000-meter tower or in your living room, a network of Wi-Fi routers allows you to use the network on the go. But the device you carry with you does not always work properly to receive the strongest signal. There may be three central stations in a small house and you should be able to choose the strongest station near you. With new chain or mesh systems, you can automatically connect to your nearest and strongest station.
  • Dense local area network. To access a Wi-Fi network, it is better to use the manual selection of the most private channel on each band instead of using automatic channel selection. One thing to keep in mind about Wi-Fi is that although all 2.4 GHz channels have a maximum signal level, the 5 GHz band is divided into three main parts and up to 2014 Each of them had a different maximum signal range. The lowest channel range (36, 40, 44 and 48) can only operate up to 5% of the highest channel range (149, 153, 157 and 161). If you are using equipment that does not follow these new rules, the best channel for your 5 GHz band is 149.
  • Use 5 GHz band as much as possible. Some routers use the same name for 2.4 and 5 GHz networks by default for easier access. But many more allow you to use different names for each band. If you want to make sure you are using the fastest connection on the strongest available signal, using separate names for the 5 and 2.4 GHz networks will help you in case of inconsistencies resulting from the use of Avoid the crowded 2.4 GHz band and switch to the 5 GHz band.

Choose the correct password

A network that requires a password to connect to it will not allow your device to connect if you do not enter it correctly. But what if you are sure you entered the password or username correctly?

  • Make sure you enter the uppercase and lowercase letters as they are when entering the password. In WPA2 passwords, the space bar is also considered as a character in the password, so do not forget the spaces in the password.
  • Make sure you choose the right network. Sometimes it happens that in some areas you come across several networks that have similar names, and it is possible that you have chosen the wrong network similar to the name of the network you want. Some companies and hotspots also separate the guest network from the private network with a slight difference in naming.
  • Networks that are under too much work pressure and routers that use problematic interfaces reject the connection even after entering the correct password. Rebooting the router and updating the firmware can help fix this problem.

Your device is constantly connecting to the wrong network

Most modern operating systems keep a list of all the networks you have ever connected to. Some systems also have access to sync, so that when you connect to a network on one device, all your other devices, such as phones, tablets, and computers, can do so without extra effort. Join the network.

If you come across a network that you used to connect to at work and it still remains on your list and you still see it when you delete it, it’s because The synced version will be returned to your device. The solution to get rid of it is to wipe it off all your devices so that nothing is left when syncing.

You can manage your networks on different operating systems in these ways:

  • Android: Settings> Wi-Fi then tap the Customize button and select Saved Network
  • iOS: In Settings> Wi-Fi you can only cancel the currently connected network
  • Windows: Click the Network icon, select Manage Wi-Fi Settings, and then select Manage Known Networks
  • macOS: Open the Network system preference section, click on the Wi-Fi adapter in the list on the left. Now click on the Advanced option and then select the Wi-Fi tab

Your network adapter may be broken

Wi-Fi adapters, like any other electronic device, have a useful life and may be damaged. If you eventually find that the adapter is not working, reinstall the operating system once, and the driver may have a problem instead of hardware failure.

You can get similar services on your computer by buying a cheap USB dongle. But on phones and tablets, repairing Wi-Fi hardware may not be possible.
