Unlike a wired network, a Wi-Fi connection requires additional authentication, since the connection to the network within the range of the signal emitted by the router is public. Here, electronics are responsible for the Internet connection and there can be many reasons why the phone does not see wifi at home: from provider problems to router malfunctions. However, this problem is extremely common, and we will look at the most “popular” reasons that the phone does not connect to home wifi in this article.
Why the phone does not connect to wifi: establishing the correct “diagnosis”
So, if your phone does not receive Wi-Fi from the router, you should check:
- 1. Is the router frozen?.
Indeed, some of the reasons that the phone does not see Wi-Fi can be safely called mystical. After all, this is what all unexplained phenomena are called? In fact, all routers without exception periodically refuse to perform the tasks assigned to them, and even the manufacturers of this equipment cannot answer why this happens.
So, if your phone stops receiving wifi after working successfully with a wireless connection, first of all you need to reboot the router. To do this, just turn off the device using the ON/OFF button on the device body (or unplug the power plug from the POWER socket), wait 30 seconds and reconnect the router to the power supply.
Thus, if the phone does not see the wifi router because it freezes, the problem will be resolved.
- 2. Correct phone authentication in the wireless network
If an authentication error occurs and the phone does not connect to WiFi, you first need to restart your mobile device.
- 3. Is the number of devices on the home network exceeded?
To find out why your phone doesn't see wifi at home, and see how many devices are allowed to use your wifi.
You may have turned on your laptop, tablet, phones, etc. and your router only supports 16 wireless connections to your home network.
Or, you bet too much, and the student from the next door decided to show his friends that he is a cool hacker. The young burglar picked up the password and gave it to his friends.
Unauthorized connections can be “banned” through the router’s web interface, after which be sure to change the password for accessing WiFi to a complex and unique one.
After changing the key, do not forget to delete all connections on your mobile communicators and connect to the network with a new password.
- 4. Is the SSID repeated?
This is rare, but it happens. Some people either set a standard network identifier or simplify the unique name to a simple one, for example “dlink”, “tplink”, etc. If someone nearby also did not strain their imagination, then the next time they connect to their home wifi network an authentication error will occur.
Turn off your router and see if its name is in the list of available WiFi networks on your phone? If a network with the same name already exists, then change the SSID to a unique one, save the settings and reboot the router.
- 5. Is your router or mobile phone broken?
Regarding the router, you can try resetting the settings to factory defaults using the RESET button
and reconfigure the device via the web interface in accordance with.
After such an “operation” all passwords will be changed to the factory ones, including authentication data
If, after completely reconfiguring the router, the phone still does not connect to the Internet via wifi, you should contact a service center or warranty workshop.
How to strengthen the Wi-Fi signal and is this even possible? The coverage area of a wireless network is affected by factors such as the type of connected router, the Wi-Fi standards used, and the number and power of installed antennas. In this article, we provide tips for those who want to improve the quality of their wireless connection.
Regardless of what device you use - mobile or stationary, there are 2 ways to solve the problem with a poor signal: setting up programs or the receiving/distributing equipment itself. Most of the tips are universal: they will help improve the quality of the Wi-Fi signal both on your phone and on your computer or TV.
Changing Wi-Fi channel frequencies
If your apartment or office is located within the reach of a large number of wireless networks, then this cannot but affect the quality of the signal. Wi-Fi networks can overlap when operating on the same channel. As a result, even if you are in a good coverage area, the signal quality can be very poor. It is for this reason that if you want to strengthen the Wi-Fi signal, you need to select a radio channel on the router.
To select a channel, you can use a special program, for example inSSIDer. In the program you can find out which channels are occupied by other people's wireless networks in the accessibility zone. We select and remember a free channel, now you need to set it in the router settings. Usually in the menu they are called: “Wireless settings”.
Improving the router
The available options depend on the provider and the settings of the equipment you have installed. A number of companies are more picky about their clients, and installing their own rather than third-party equipment is preferable. Often providers offer lists of devices that support their services; it’s worth checking with them too. In the end, if your tariff specifies a certain speed, it is the provider’s job to do everything to provide you with service at the stated level.
You can buy more, which will cost a couple of hundred dollars. But why go to such extremes? Better look at what can be done with an existing device, check its characteristics. It is also possible to replace the antenna, although many models that have appeared in the last couple of years simply do not have additional connectors to allow you to add your own antenna. But if your model allows this, check the documentation for the router - you may be able to strengthen the signal in this way or redirect it.
On some routers, advanced settings allow you to adjust the Wi-Fi signal strength. In the “Advanced settings” section, look for the “Operating mode” or “Transmission power” parameter. To indicate this parameter, either percentages or abstract values (high, medium, low) can be used. We recommend setting the maximum value and clicking the “Save” button.
Transition to 5 gigahertz frequency
Most routers operate at a frequency of 2.4 GHz, in this frequency there are only 13 intersecting channels, of which only 3 channels do not intersect each other. In the 5 GHz frequency, which most modern routers operate on, there are 19 channels and 7 of them are non-overlapping, which means you will have twice as many opportunities to connect to an open channel. And considering that while Wi-Fi points with a frequency of 5 GHz are not a common phenomenon, there will be practically no influence of neighbors’ points on your Internet.
Using the 802.11n standard
The choice of wireless standard directly determines the strength of the Wi-Fi signal and the coverage area of the router. The 802.11n wireless standard has an advantage over other standards - an increased coverage area due to the simultaneous use of multiple antennas. If you have not yet solved the problem of how to strengthen the Wi-Fi signal, then be sure to try switching to the 802.11n standard. Please note that all your connected devices must support this standard. Otherwise, the wireless network will simply be unavailable for these devices.
Changing the location of the modem
Since the router emits a signal in all directions, it would be ideal if it could be located somewhere in the middle of your apartment. The closer the router placement is to this option, the better. Thanks to this, you will not have remote rooms, they will all be at an equal distance. The second step is to raise the router to its maximum height. It is best to place it on a shelf near the ceiling.
Baby monitors, cordless phones and microwave ovens can also affect the signal.
Antenna interference in mobile devices
Many smartphone cases can degrade Wi-Fi signals, especially if they contain metal used to make the case stronger. To find out whether your case affects the quality of your Wi-Fi signal, run a speed test on your smartphone with the case removed. Then, while still in the same place, put the case back on the device and perform the above test again. If you see a difference in the test results when the case is on your smartphone, then you should look for a different case.
Setting up power modes on a laptop
Laptop users do not always keep track of what battery mode is currently set. When the battery charge is low, the power saving mode is almost always activated, which users forget to change after connecting the computer to the network. At the same time, a lack of power can negatively affect the operation of the laptop's Wi-Fi adapter, which in turn will affect the signal quality. If the question of how to strengthen the Wi-Fi signal remains relevant for you, pay attention to the power mode.
Installation of signal amplifiers
In the case of amplifiers, there are two options. The first is retransmission of the original signal over a greater distance with a loss of speed along the road. The second is a wired device that uses your home electrical network to transmit information to and from the router. The second method is more preferable.
For those who prefer repeaters, any solution is available for any amount; you can even find programs for old routers in the public domain. After installation, all functionality is available to you, and then you should, as described above, try to avoid conflicts with other devices as much as possible.
When it comes to connecting to your home electrical network, there are various options available. For example, you can read it on our website. Some devices provide wired connectivity in a selected room, while others create separate Wi-Fi hotspots.
For a normal use case, a repeater is enough, but if you are interested in HD video streaming, then buy wired devices. And in this case, it is better to overpay for a good device from a trusted manufacturer, since such an investment with a guarantee will be long-term.
According to statistics, more than 80% of Internet users in Belarus connect to the Internet via a wireless connection. At the same time, many are faced with a problem when the actual Internet speed does not correspond to that stated in the tariff plan. By following the tips described above, you can improve the quality of your wireless connection and use Wi-Fi networks comfortably.
If you notice that your Wi-Fi is using a lot more power than usual, or the connection is there but the internet is not very fast, then the problem may be a bad Wi-Fi connection. Wi-Fi problems can occur anywhere from buildings with thick walls to long range or simply a bad Wi-Fi signal. Here's our guide on how to boost the Wi-Fi signal on your Android smartphone.

Changing Wi-Fi frequency to 5 GHz
Most Android devices can operate at 5 GHz, as well as the older version - 2.4 GHz. What does it mean? At higher frequencies, such as 5 GHz, there is much more free space in the spectrum. At 5 GHz there are 23 channels of 20 MHz each, which is much more than the 14 channels that exist at 2.4 GHz. Since the channels don't overlap, you'll likely get a better Wi-Fi signal.
If your router operates in the 5 GHz band (like the newest routers), then switch your phone to the same frequency by going to Settings > Wi-Fi > Advanced > Wi-Fi frequency, and click Auto. This will keep your phone running on the 5GHz frequency whenever possible.
Accurately track Wi-Fi signal
Have you ever been in a situation where you have to wander around a building looking for the perfect signal, only to end up realizing that those Wi-Fi signals aren't good enough? To really catch the best Wi-Fi signal in your area, download Wi-Fi Signal Booster, click Manual Boost, and keep an eye on the red line as you wander around looking for it.
The closer the red line (current signal) gets to the yellow line (available signal), the better. Click Automatic Improvement to get a quick yet powerful boost to your Wi-Fi signal.
Tell your phone to avoid bad connections
There's a nice option in the Android settings menu that forces your phone to avoid bad Wi-Fi connections. This means that while scanning for available networks, it will not attempt to connect to those with a poor signal. This will save you a lot of hassle and disappointment. Just go to Settings > Wi-Fi and tap the three dots menu button and then Advanced. Here you will see a checkbox that will help you avoid bad connections.
Update your radio or software
If you receive over-the-air (OTA) updates from a carrier or manufacturer, then this probably doesn't apply to you. But if you have a custom ROM installed, then sometimes you may need to manually update the radio on your Android. As an example, here's how to update the bootloader and radio on your Nexus 5. For better performance, you should also make sure you have the latest version of Android. To check this, go to Settings > About device > Software update.
Make sure your case is not blocking the signal
Many phone cases actually make Wi-Fi signals worse, especially if they contain metal, which is often used for added protection. To find out if your case is affecting your Wi-Fi signal, do an Ookla speed test by removing the case, then putting it back on your phone in the same place and running the test again. If you see a difference when using the case, then you may want to find an alternative.
Find out which Wi-Fi access point is the best
One way to do this is to use the Wi-Fi analyzer app, which has three useful features. First, it finds the best channel to use for your specific network. Without going into too much detail, it allows you to optimize your network, which means you don't have to be technical to do it.
Secondly, it evaluates which network in your area has the most stable connection and which does not, which your phone connects to by default. Finally, it offers easy access to network information such as your network gateway IP address, DNS, etc. This is optional, but useful for advanced users.
Place your router in the optimal location
Another simple way to significantly improve the Wi-Fi connection in your home is to optimize the location of your router. This will often be in close proximity to the phone or cable outlet, but this is rarely the best location for your connection. If you can move it, take a look at the FDTD solver app, which will let you see at a glance what kind of signal your router is producing.
MacGyver a DIY radio
All the above options don't work? It's time for an old school feature. If you really need a better Wi-Fi signal, you can make your own small dish antenna to catch it better. It's actually a small version of a large radio or satellite dish. You can use a metal bowl or a cut up soda can to make a receiver. It might not be the most practical thing to do every time the signal gets weak, but it's fun.
Have we missed any methods? What do you do to strengthen your Wi-Fi signal?
Owners of mobile devices with an apple on the body are quite rarely faced with the problem that the devices do not pick up WiFi or the mobile operator’s network than owners of phones from other brands. But sometimes this can happen to them too. With proper and careful use, the occurrence of such a problem is practically impossible, and if it does occur, a simple reboot of the device is enough, but it often happens that the problem is much deeper and needs to be sorted out Why is iPhone bad at Wi-Fi?.
Possible causes of the problem
The main problems that are not related to the operation of an iPhone or iPad include the following:
- When updating iPhone 5, iPad Air, iPad models with retina display to iOS 8, a sharp drop in data transfer speed was noticed. Signal deterioration was also noticed on iPhone 6.
- The build quality of the phone is not satisfactory, but due to design features there are problems with data transmission via WiFi, especially when it comes to the issue Why does Wi-Fi work poorly on iPhone 5?. This is due to the fact that the phone has a weak radio signal amplifier.
If the phone was dropped, subjected to other physical impacts, or water got on it, then completely different, purely mechanical damage occurs, which can lead to the following:
- the radio module has come off the phone's motherboard;
- The WiFi module cable is damaged;
- physical damage to the antenna;
- Damage to PCB tracks.
After finding out the reason why iPhone does not receive Wi-Fi, what should I do? The best advice will be given by specialists from a certified service center, but before taking the device there, you can try a number of ways to solve the problem yourself.
Troubleshooting: Required Actions
The sequence of actions to solve the problem yourself depends on the iPhone or iPad model and the version of the iOS operating system. General procedure that can restore functionality:
- Turn off Wi-Fi on iPhone.
- Delete saved WiFi networks.
- Turn off and then turn on the router after a while. This will reset the settings on it for all previously connected users.
- Turn on Wi-Fi on your gadget.
If after all this iPhone doesn't have good Wi-Fi connection, you need to try connecting to the router with another device to exclude the possibility of it breaking.
There are situations when the network is found very quickly and connects without problems, but when you try to open any page in the browser it is not possible. You can eliminate this by switching the key check from WPA to WEP in the security settings of your WiFi gadget.
Reset network settings and force reboot
Another possible way to solve the problem is Why is Wi-Fi bad on iPhone 6? This is a network settings reset. To do this, go to “Settings” on your phone, “General - Reset” tab, and select “Reset network settings”. It is strictly not recommended to do a full reset, because... this will result in complete destruction of data on the device. If you still need to do such a reset, then it is advisable to synchronize the device with your computer via iTunes, save the contacts and upload the data to the cloud.
Quite often, a “hot” reboot of the device, especially with the release of the eighth generation operating system, solves the problem, Why doesn't Wi-Fi work on iPhone 7?. To perform this, you need to simultaneously hold down the “Power” and “Home” buttons on the device that is turned on. The phone will turn off. After turning on, the operating system cache and RAM of the phone will be cleared.
What to do if nothing helps
If after all the manipulations the problems remain, then we can say with almost one hundred percent probability that Why can't my iPhone connect to Wi-Fi?- critical damage was sustained during operation and it is necessary to take the device to a service center.
It is advisable to choose a certified service center, and if this is not possible, then at least be guided by the reviews of previous clients. This rather critical choice will affect the future performance of your iPhone. For example, when assembling a phone incorrectly, many careless craftsmen forget to press the metal plate tightly (or even lose it) to the contacts on the motherboard, but these plates are the iPhone’s antenna.
Poor Wi-Fi reception on iPhone? iPhone constantly disconnects from the Wi-Fi network and resumes operation only after a while? Wi-Fi speed on iPhone has dropped noticeably and still won't return to normal? If you are facing any of these issues, this guide will definitely help.
Perform a force reboot
You should start looking for a solution to the problem of poor Wi-Fi reception on the iPhone with the simplest method - performing a forced reboot. It helps to reset iOS software errors that have arisen, including even those that at first glance are related to the hardware. In order to force restart your iPhone you need to hold down the buttons Nutrition And Home(Volume Down button on iPhone 7/7 Plus) and hold them until the Apple logo appears on the screen. After turning on the device, you should check that Wi-Fi is working correctly.
Reconnect to the Wi-Fi network
Also, quite often, a simple reconnection to the network helps solve the problem with a poor iPhone connection via Wi-Fi. For this:
Step 1. Go to menu " Settings» → WiFi.
Step 2: Select a wireless network that is slow.
Step 3: Click " Forget this network».
Step 4: Search for wireless networks and connect to the network you just deleted.
Please note that after resetting, the Wi-Fi network password will need to be entered again.
Reset network settings
One of the most effective ways to solve the problem of poor Wi-Fi connection on iPhone is to reset the device's network settings. It is performed as follows:
Step 1. Go to menu " Settings» → « Basic» → « Reset».
Step 2: Click " Reset network settings».
Step 3: Confirm the operation.
After resetting the network settings is successfully completed, you can check whether the iPhone works faster on your Wi-Fi network.
Use an alternative DNS server
The next method is non-standard. In the connection settings, you must specify an alternative fast DNS server, for example, Google. This will allow the connection to work faster on your specific device.
Step 1. Go to menu " Settings» → WiFi.
Step 2: Click " i» next to your connection.
Step 3. In the DNS column, enter one of the following DNS servers:
- Google - 8.8.8.8.
- Google - 8.8.4.4.
- OpenDNS - 208.67.222.222.
- OpenDNS - 208.67.220.220.
After that, exit the connection settings and check if its speed has increased. 
Set up a different Wi-Fi network broadcast channel
This method is especially helpful for people who live in apartment buildings literally teeming with Wi-Fi networks. The vast majority of networks operate on standard settings, broadcasting on the same channel. Installing another Wi-Fi network broadcasting channel makes it possible to significantly speed up the connection.
However, you will have to find the option to select a broadcast channel in the settings of your router yourself. The fact is that router management interfaces have different appearances, which is why, unfortunately, we cannot give the exact location of the required settings. Note that most often the option to change the Wi-Fi channel is available in the advanced connection settings.
Set a Wi-Fi password
And one more tip related to Wi-Fi network settings is extremely simple. Make sure that other people are not using your Wi-Fi, thereby slowing down the connection speed. The easiest way to do this is by setting a Wi-Fi password, thus prohibiting other users from connecting to the network.
Restore iPhone
If a problem with Wi-Fi appears after installing an update on your iPhone, it may be due to a serious software error. You can get rid of it by restoring your iPhone via iTunes to the current version of iOS. You can find a detailed guide on how to restore an iPhone using iTunes.
If none of the above methods help, then you cannot do without the help of service center specialists.
