If you went to this page, then most likely you are faced with the problem of an unstable connection over a Wi-Fi network, and the connection itself is often cut off. You probably already guess why this is happening. Most likely, your apartment has a lot of Wi-Fi networks, and due to interference from these networks, you have problems with your Wi-Fi connection and constant disconnections.
This problem is very popular now. If you live in an apartment, then most likely all of your neighbors have Wi-Fi routers installed, each broadcasting a wireless network. And it turns out that all these networks intersect one with one. Almost all Wi-Fi networks now operate at 2.4GHz. All of these networks operate on channels from 1 to 13. And when there are a lot of these points, it turns out that two or more Wi-Fi networks can operate on one channel. It is precisely because of such interference that wireless connection problems may arise on your devices. And as practice shows, it is not even necessary that there are many neighboring access points. There may be several of them, but they can be suppressed in some figurative way and create interference.
Several times I have already seen cases when the Internet via Wi-Fi did not work at all in the apartment due to the large number of neighboring wireless networks. Either the devices did not connect to the router at all, or they connected and immediately lost the connection. There are also cases when there is a connection, but the Internet works very slowly, or does not work at all. I already wrote about a similar problem in the articles "Wi-Fi is unstable. Why does the Internet drop through a Wi-Fi router", and "Why does Wi-Fi turn off on a laptop".
As for the solution to this problem, first you need to experiment with the channel on which our Wi-Fi network works. If it doesn't help, then you need to switch to a new and freer 5 GHz frequency.
Unstable Wi-Fi operation due to a large number of neighboring networks
Let's try to deal with this problem point by point. First you need to find out if the problem is in your access point (router), or in some particular device.
1What is the reason. See, if all your devices connect well to the Wi-Fi network, and keep the connection stable, and one device is unstable, then the problem is most likely in this device. Typically this laptop, or a computer with an adapter. In this case, the solution must be sought on the device itself. If this is a laptop, then check how it works with other networks, put it next to your access point, and check it works. Update your Wi-Fi adapter driver. Perhaps the problem is not in interference from neighboring networks, but specifically in this device.2 Since we have problems most likely due to interference on the Wi-Fi network channel, then we need to try changing the channel of our wireless network in the router settings. There are several different options to try. Or, use the inSSIDer program to find a free channel.About finding an unloaded channel, and how to change this channel on different routers, I wrote in a separate article on how to find a free Wi-Fi channel, and change the channel on a router.
This is how it looks on an ASUS router:
Try different channels. Remember to save your settings and reboot your router after each shift.
3If changing the channel does not help, and you are sure that the problems with the wireless network are due to interference from a large number of neighboring Wi-Fi networks, then there is one proven option. Transition to 5GHz frequency. True, you will have to buy a new router here. We will need a dual band router. It would be nice to first borrow such a router from someone and check how a 5GHz Wi-Fi connection will work in your house. If everything works well, then you can think about buying a new router. I recommended some models in the article on choosing a router for a house or apartment.However, please note that most likely not all of your laptops, smartphones, tablets, and other devices will be able to connect to a wireless network at 5GHz. Older devices do not have support for this technology. I wrote about this in this article.
This is the case when it is very difficult to advise something specific. After all, an unstable connection to a Wi-Fi network can be due to anything. The same interference from a large number of neighboring networks, interference from some household appliances, problems with the adapter itself on the device, breakdown of the Wi-Fi router (often power problems), etc. Here you just need to experiment and look for the culprit ... If anything, you can always leave questions and your advice in the comments below.
