Another cause is that there is incompatibility with the wifi bands. Current wireless routers and repeaters are usually dual band. That means they can work on both the 2.4 GHz and 5 GHz frequencies. Each of them has its advantages and disadvantages, but basically we can say that the first one goes further, although it offers less speed; instead the second will have less range but more speed.
The problem comes when we have a device that is not dual band. If you see that the repeater network does not appear when you join from some device, it is possible that it is not dual band and the network that should be displayed cannot use it. This is rare to happen on a computer, but it is not so rare on a mobile or tablet, especially if they are somewhat old.
Some failure in the repeater
Of course, another reason is that there is some repeater problem wireless. There may be some fault that prevents it from offering a good signal. It may be intermittent or that it has so little strength that it does not reach the devices where we are having errors and we see that the Wi-Fi network does not appear.
If you see that on certain computers they do appear or even sometimes you can see it, it could happen that the repeater does not work correctly. That means that the problem is not so much the device you want to connect, but the repeater itself.
Wi-Fi encryption is not supported
There are different types of ciphers for keys of Wi-Fi. There are some that are older and will be compatible with the vast majority of devices, but the most recent ones may be incompatible. You might have trouble connecting to a wireless network that has WPA-3 or even WPA-2 encryption.
If you are using an older device, such as a tablet from several years ago, you may not be able to find the Wi-Fi network simply because that extender uses WPA-2 encryption. As it is not compatible, it would not be able to connect and it would not recognize that network. It’s not common, but it can happen on older computers.
On the other hand, there is the problem of saturation. Wireless repeaters have a maximum limit theory to connect devices. But even without reaching that limit, there could be problems if you have too many devices connected. This will depend on the Wi-Fi repeater, as some will have more capacity than others.
If you search for Wi-Fi networks and the wireless repeater next to you does not appear, think that it may be saturated. It is possible that there are too many devices connected there and it does not have more capacity to support one more.
What to do to avoid failures with the repeater
As you have seen, there are times when the Wi-Fi network of a repeater does not appear. To avoid this, to try to make the device work as well as possible, you can take into account certain tips that we are going to give. The goal is to make the Internet connection work as well as possible.
locate it correctly
Something very important is position the device correctly. Ideally, it should be in an area from which it can distribute the signal well. It is useless to put it very far from the router and receive a weak signal and then not be able to connect from other devices. Therefore, putting it in a place where it receives a good signal and can distribute it later is the key.
You should also keep in mind to put it away from other electronic devices that may affect the quality. If, for example, you place it next to a television, it could generate interference and make the Wi-Fi connection not work well. The best thing is that it is in an isolated area, in an elevated location and without obstacles.
keep everything up to date
You should always have everything Updated successfully for optimal performance. This also includes the devices that you are going to connect, such as the computer or a mobile phone. Always install the latest versions of the network card drivers and this way you can achieve better performance of the wireless network when you connect to a repeater.
In the case of Windows, to update the Wi-Fi card drivers you have to go to Start, enter Device Manager, Network Devices and select the corresponding card there. You have to click the second mouse button and click Update driver.
Use cable if possible
One more tip to get the best internet speed when using a repeater is to connect your devices via cable instead of Wi-Fi. Not all of them have this function, but if so, it is something that you can take into account and surely you will also improve stability and avoid annoying cuts.
However, you must make sure to use a good wire. The interesting thing is that the repeater has a Gigabit Ethernet port. This means that it will reach speeds of up to 1 Gbps. If it were Fast Ethernet, you would be limited to 100 Mbps. The cable you use, in order to take advantage of Gigabit Ethernet, must be a minimum of category 5E.
In short, there are several reasons that can cause the Wi-Fi network of the repeater not to appear. This could affect your connections. You can take into account some recommendations that we have given to ensure that the connection works as well as possible, without interruptions and with a good speed.
