If you entered this page, then most likely your phone stopped seeing the Wi-Fi network, or network. It can be a home network, somewhere visiting a public wireless network, etc. The problem is that the network you need does not appear in the list available on the phone. He simply does not find it, does not see, and accordingly it will be connected to such a network. Not rarely occasion when mobile device Does not find some particular Wi-Fi network. Which, for example, a laptop sees without any problems and connects. Or maybe such that the phone does not find any network, and other devices see them and work perfectly with them.
In this article, I will try to collect all the most popular causes and decisions that can help you in solving this problem. As usual, it is advisable to find out what the problem is: in mobile phone, or Wi-Fi Routere. If a problem with Wi-Fi network at home, then we have more chances to fix everything, as there is access to the router itself. If it is someone else's network, it is unlikely to do something.
In fact, there is no big difference on which device you have a problem. It is clear that it is most likely the phone on Android, or iOS. Well, maybe more Windows Mobile. Since in the settings of the mobile device itself this problem can be solved, then without a difference you have a device. Similarly, with the router.
I already wrote separate articles on devices on Android and iOS:
The phone does not see Wi-Fi Router: Possible Causes
1 Disable / enable Wi-Fi, restart the phone and router. To begin with, just go to the settings of your phone and turn off Wi-Fi. I think everyone knows how to do it.Then turn on the back.
Reboot your phone:
- In Android, it is enough to press and hold the power button, then select "Reload". Depending on the manufacturer and android versionThe actions can be slightly different.
- On the iPhone you need to hold and hold the "Home" button and the "Power" button. The phone will be rebooted.
Restart the router. If you have access to it. It is enough to turn off the power and turn on the router again. You can perform several reboots in a row. You can read more detail.
2 Determine what is the reason.Check out all three items:
- If your phone does not see any Wi-Fi networkBut they are and other devices find them, then it is clear that the problem is specifically in your smartphone. All I can advise, to reboot it, and remove the cover from him. If he is. If this does not help, you can try to perform full reset settings. If it does not help, you will have to carry the device to the service center.
- When the device does not find one network, then the first thing you need to check whether its other devices see. If you do not see, then most likely the problem on the side of the router. First reboot it. If it does not help, then see the article :.
- If other devices find a Wi-Fi network, and your phone is not, but it sees other networks, most likely the problem in the router settings. As a rule, helps changing the channel of the wireless network and region. Below I will talk about this in more detail.
Need to go to the settings of your router, go to section with wi-Fi settingsAnd try to set the static wireless channel and another region. You can also set the width of the channel 20 MHz. Better in turn.
On TP-LINK routers it looks like this:
In more detail in the article :. You can experiment with the canal and the region. For example, put the US region. If you have a static channel in the settings, then put "Auto".
Other problems with discovery Wi-Fi networks
I also noticed that the people often writes the telephone phone does not see the Wi-Fi laptop. I understand that the problem arises when distributing the Internet from a laptop, or PC. In this case, I advise the first thing to make sure that the laptop distributes the wireless network. For example, look from other devices. You may have incorrectly launched an access point. Here you will use the article. Apply the phone closer to the computer.
The next case, when problems with Wi-Fi appear after repairing the phone. For example, after replacing the battery, screen, glass, housing, etc. in such cases, I advise you to immediately attribute the phone to the workshop where it was repaired. Since the master most likely did not connect the antenna, or the Wi-Fi itself module.
Well, no need to exclude the hardware breakdown. Everything breaks, and the module that is responsible for connecting to Wi-Fi is no exception.
As usual, you can leave your question in the comments, or share useful information on this topic. Always happy to answer your questions and thankful for additions to the article.
As you know, some models of routers (from new, mostly) support the mysterious 5GHZ WiFi, that is, the same "5-gigahertz wi-fi", which seems to automatically mean not only a "fast" Internet, but also a more sustainable connection.
In fact, it is approximately about there (although not always), but now it is not about that. And how to find out whether your laptop is supported by this 5GHZ WiFi, and if so, how to turn it on.
The fact is that, in contrast to the ordinary and usual to all users of "Wai-Faya" (when only the name of the router, to select and enter the password), 5GHz WiFi, figuratively spending up, just so in hand is not given, and to turn it on a bit Podnaping your favorite brain muscle.
But better in order.
how to find out if your 5GHZ WiFi router supports?
This is the case if you really do not know how many bands do you have a router, 1- or 2, and whether it supports 5-gigahertz WiFi at all. Because if it does not support it, and there is no other suitable available, it is still in a hurry with inclusion of 5 GHz in a laptop, as it were, and there is no need. So we find the packaging or manual of the router's user and read it a brief specification. Or open the router settings directly from the laptop and get acquainted with Wi-Fi parameters.
By the way, since these settings you have already found, you can slightly subsertaining something. The fact is that on the time, in some 2-range routers, the same SSID is registered (a unique network name that distinguishes one Wi-Fi network from another) both for 2.4GHz and 5 GHz. If such started, it would not be superfluous to change it so that in the future it could be easier to find the appropriate network at least from a laptop, even from a tablet or smartphone.
what are Wi-Fi standards on 5GHZ?
On 5GHz, 802.11a, 802.11n and 802.11ac, 802.11n are optional. And since most of the current routers are just a model of the 802.11n standard, it is necessary to specify whether support for 5 GHz WiFi is provided under hand. In addition, not each router supporting 2GHz and 5GHZ WiFi, can work in both bands at the same time. So, if your also of those, then it is possible that 5GHZ WiFi is better not to run.
After all, if in some of your mobile devices that you use daily, the support for 5GHZ WiFi is also not provided (and many models it is not provided), then switch the router on 5GHz is not entirely appropriate. Of course, modern dual-band routers such problems usually do not happen. But there are problems with the devices connected to them, which may lose touch with each other, and then it turns out unnecessary catavation. When, for example, the iPhone 7 connected to the home network on 5GHz suddenly stops seeing your MacBook, which is connected to the same network and through the same router to 2.4GHz.
how to find out if your 5GHZ WiFi laptop is supported?
With this, too, not just. The most affordable method of the usual jower is to go to " Device Manager " (through " Control Panel") And in the tab" Network adapters »Find the exact name of the built-in WiFi laptop adapter. Next, you can google the detailed specification of this device by its name. If you read that the laptop wifi adapter supports 802.11a and 802.11ac, it means that the 5GHZ WiFi is accurately supported.
There is another option:
in " Device Manager »We click on the right mouse button by the name of the WiFi adapter, in the menu that appears, select" Properties ", Go to the tab" Additionally "And in the list of properties We are looking for a mention of 5GHz. If the switching option to 5GHZ WiFi cannot be found, then either in your laptop it is not supported at all, or there is a fact that the wifi-adapter is incorrect drivers (it happens).
However, if you really need 5GHZ WiFi, the question is guaranteed to be engaged in the purchase of an external WiFi adapter. It is worth such a devicor inexpensively and allows you to do without the whole bustle described above.
By the way, about bustle. As we know, work related to data recovery, replacement of components, removal malicious programs, installation and configuration operating system etc. Faster and more efficiently performed by qualified specialists. In this regard, knowledgeable people advise extremely carefully to choose from the company whose staff can be entrusted with their laptop. vlatar.com.ua. - This is the case if or when a workshop is needed with a good reputation specializing in the repair and maintenance of any laptops. Not prevent.
Bought today tP-LINK router Archer C20i to test it, and write a few instructions for setting up. One dual-band, broadcasts the Wi-Fi network at a frequency 2.4 GHz, and 5GHz. Included it, and found that the laptop, and my phone does not see the Wi-Fi network, which is translated at 5 GHz frequency. But the tablet ipad mini. 2 I found this network without any problems, and connected to it. New phone Meizu. M2 Note also saw a new network without any problems.
Everything is very simple and understandable here. Not all devices can be connected to Wi-Fi networks that operate at a frequency of 5 GHz. The adapter built into the laptop simply does not support these networks. Since dual-band routers appeared relatively recently, only new devices can operate in these networks. And if you decide to switch to 5 GHz frequency, then you need to make sure that your devices are supported. True, dual-band routers broadcast two Wi-Fi networks, on 5 and 2.4 GHz. Therefore, devices that do not support the new frequency can be connected to a regular wireless network.
If briefly about Wi-Fi networks at a frequency of 5 GHz, then the main advantage is that this frequency is more free and there is less interference. It simply already has places where to use 2.4 GHz is simply impossible, due to a large number of networks and interference. And does not even always save. Of the minuses - a smaller range of Wi-Fi network, compared with the frequency of 2.4 GHz.
So I decided to make a little note, and explain why some devices do not see the Wi-Fi network on a new frequency, and how to find out if your laptop supports, or another 5 GHz range network.
One important moment. If support is indicated in the device characteristics, it is precisely able to work with networks in the 5 GHz band. But if it is indicated only 802.11a / b / g / n.This does not mean that there is no support for the new frequency, since the frequency of 5 GHz works with an 802.11n and 802.11ac standard.
How to find out whether 5 GHz laptop supports?
First of all, see the characteristics of your laptop, preferably on the official website. If there is an 802.11ac support, Dual-Band Wi-Fi, or is simply written 5 GHz, it means everything is fine.
You can still go to the Device Manager, and open the Network Adapters tab, right-click on the Wireless Adapter, and select Properties. Further, go to the Advanced tab, and there must be information on support 5 GHz.
The inscription "Dual Band" itself in the title Wi-Fi adapterand says that there is support for networks in two ranges.
I have no such support in my laptop, and there is no information in the device manager there is no information.
And if you have included a two-way router, and the laptop sees only one network, then it is clear that there is no support for the 5 GHz frequency.
Support Wi-Fi 5GHz on smartphones and tablets
As for mobile devices, all information on wireless modules is indicated in characteristics. If it is written about 802.11ac support, Dual-Band, or 5 GHz, then everything is supported, and will work.
What if there is no support 5 GHz?
Just connect to networks at a frequency of 2.4 GHz. And if you just need to go to a new frequency, and the laptop does not support it, then in this case you can buy external USB Wi-Fi adapter that supports the frequency of 5 GHz. For more information about these adapters, I wrote. True, such a decision is possible only for laptops, and stationary computers. If you have a mobile device, you will have to measure.
There are no special and serious advantages in the new frequency. And the transition to new standard will happen automatically with time, even unnoticed for us. As I have already written above, the exception is the places where it is already simply impossible to use the wireless Internet at a frequency of 2.4 GHz, due to the large amount of interference.
If the device supports networks at 5 GHz, but does not see them
If you are welded that your adapter, laptop, or mobile device supports networks at 5 GHz, but does not see them, you can try to experiment with the channel settings and the channel width of the Wi-Fi network. You can change these parameters in the router settings in the Wireless Settings section. Try, for example, put the width of the channel 40 MHz, and some static channel from the list. Just do not put too high channel. You can set 36. Or leave the channel on the car, and change only the width of the canal. I showed on the example of the router from TP-LINK.
After changing the settings, do not forget to save the parameters and restart the router.
