Good time everyone, for two whole days I did not write anything. And so today I will tell you why the wifi is connected on the tablet but there is no Internet. In view of the fact that many of the tablets used are based on the popular Android OS, I will talk specifically about solutions to problems with such devices.
The problem that lovers of tablet devices face when working with the wireless Internet is the display of the "Obtaining an IP address" line. The operation of the gadget at this stage stops and is not restored in the future. There are actually a couple of methods for solving the above problem, one of them should definitely help.
- Change the name of the Wi-Fi network to any other that includes only English letters.
- Reload the router (this trivial method is often the most effective).
- Change the type of data encryption (in the same place as the name of the wireless network, you must change the type of protection to another).
For the entered settings to be applied, the modem needs to be rebooted.
Preparatory process
For today I have everything, I hope you now know why the wifi is connected on the tablet and there is no Internet. I want to ask you about something else, if something doesn't work out for you - write about it in the comments. I will also not refuse if, as a token of gratitude, like this article. I wish everyone only positive emotions and good health.
From Uv. Evgeny Kryzhanovsky
We live at a time when almost any operation can be performed using a smartphone or tablet. When on the Internet you can find absolutely any information in a matter of seconds. When, sitting at home, at work or even on the road, you can listen to any music or watch any video that has ever been uploaded to the network. What can confuse or upset us the most in our time? Only the moment when, unexpectedly for us, a phone or tablet does not connect to Wi-Fi, and we do not have the opportunity to access the Internet. Why sometimes a phone or tablet does not connect to Wi-Fi, why errors occur when trying to connect, and how to deal with them, we will consider in this material.
There can be many reasons why the device does not connect to the wireless network.
It is worth clarifying right away that this small collection of guides is of equal value to those who go online using a phone and those who use a tablet for this purpose. The Wi-Fi module in these devices works identically, so if problems arise when connecting to the Internet, the solution is most often the same for all users and devices.
Most often, Android users have problems accessing the network, but the system itself gives much more information about a particular problem that arose during connection. That is why we will consider the problems of connecting to Wi-Fi using Android as an example.
When the user connects to Wi-Fi, the Android phone may display error messages containing different text. It is this text that will help us determine why the device cannot connect to the Internet, and will also help eliminate the cause of this problem.
After selecting one or another access point, the phone may display the following messages:
- "Obtaining an IP address ..."
- "Authentication ..."
- Disabled.
- "Saved, WPA / WPA2 Security."
And also there is a situation when the connection was successful, but it still fails to open the pages.
In the case when an Android phone or tablet does not connect to the Internet via Wi-Fi and constantly reports only that an IP address is being obtained, the simplest thing you can do is delete the network and its settings from the device memory and try to reconnect. To do this, click on the name of the access point in the device settings and select the "Delete" option in the context menu. Try connecting again after a few seconds. In this case, your phone or tablet will require you to re-enter the password, so if you are connecting to a router other than your home router, you should check in advance that the password is correct.
Authentication
The reason why an Android tablet or phone can constantly display such a message is most likely in the password. First, you need to make sure that you have entered all the characters in the password correctly and have not made a typo anywhere. If the Internet does not turn on for a long time, displaying a similar message, delete the network as described in the previous paragraph of the instructions and try to connect again. Secondly, if this is not the first time you are connecting to the selected Wi-Fi network and the connection was successful before, you should check if the password has changed since the last successful connection. This is true for cases when the smartphone or tablet is not connected to home Wi-Fi.
Problems not related to the mobile device
All subsequent tips that we will give you in this material are in one way or another related to the settings of routers, so they will be relevant in the first place when your tablet or smartphone is having difficulties accessing the network directly at your home. That is, where you can independently change the settings of the network equipment.
First, you need to find out why your gadget does not work with the selected access point, why it refuses to connect to it, and then change some of the router's settings by going to its control panel through any browser or through a mobile application, if provided by the manufacturer.
If your Android tablet or smartphone can't connect to the Internet in your home, the reason may be simple. Despite the fact that visually it may seem that the router is working, its software may be frozen. In this case, a reboot will help. Unplug the device and wait a few seconds (7-10). Then plug it back in and make sure it works by checking the indication. After a few seconds, check if the mobile device sees the hotspot and try to connect again. If the gadget does not see the network, most likely the router is still turning on and you need to wait from a few seconds to a minute.
password change
If the gadget sees the access point, but you cannot remember the password for your wireless network located at home, you can change it at any time in the router settings. To do this, go to the appropriate section of the settings and set a new combination of symbols. There must be at least eight of them. Save changes and reboot the router. Please note that after this procedure, you will need to enter a new password into each device that works with this access point and receives a wireless signal through it.
Changing the encryption type
In some situations (this is especially true for budget-class Android devices), it may turn out that the built-in Wi-Fi module does not work with some types of encryption. This leads to the fact that the device sees the access point, but only displays the "Disabled" error and does not connect to the Internet. To fix this problem, you need to open the settings of your router and change the type of encryption with which your mobile device works. We recommend choosing between WPA / WPA2 and WPA-PSK types. These encryption standards are supported by the largest number of devices.
Channel change
For some situations in which the mobile gadget does not connect to the Internet via a wireless network, it will also be useful to change the channel through which the signal is heard. The reason for changing the channel may be a situation when the device sees the access point, but the connection does not occur. This is also due to compatibility issues between network equipment and the Wi-Fi module. In total, you will find up to 12 channels in the router settings, but, as a rule, not a single budget gadget on Android works with a channel higher than the ninth one. Consider this information when setting up your network.
Disable MAC and IP Filters
In a situation where the network equipment is tested and functions correctly, the mobile gadget sees the access point, several similar devices enter the network through the same device, but the smartphone still does not connect to the target network, it is worth looking into the MAC and IP address filter in the parameters router. Sometimes the network equipment is configured in such a way that only specific devices located in your home can get the right to access the Internet, the MAC and IP addresses of which are registered in a special section of the control panel of the modem or other network equipment. Disable all unnecessary filters and restart the router. Do not forget - it turns on from a few seconds to a minute, and only after that it is worth checking whether the mobile device sees the access point.
Conclusion
As you can understand from our small instructions, almost any problem that occurs when you connect a mobile device to a wireless network can be solved in a couple of minutes, having the necessary information and access to the settings of the network equipment. We hope that our instructions helped you in eliminating errors and now you can easily access the Internet from any of your gadgets. If this does not work out, we recommend that you go through the entire list from start to finish and try to use all the tips without exception.
Is your tablet unable to see the Wi-Fi network, or is the connection failing? Is the signal weak or unstable? One or more problems indicate a problem with the mobile device and / or network equipment. To solve the problem, we have prepared an exhaustive material where you will find the cause and remedy for the breakdown.
How to identify a malfunction
When using the Internet, the chain consists of a provider, network equipment, and a user device. Therefore, in order to quickly solve problems, it is important to determine on which side the malfunction occurred.
Find out if there is an interruption to the availability of the Internet from the provider. To do this, connect an Ethernet cable to the network card of your computer or laptop. If this is not possible, call your provider and ask if there are any disruptions to the Internet at your address.
Connect another device to the router, preferably with the same Wi-Fi module specification. If other equipment is connected and working properly, the problem should be considered in the mobile device.
Connect your tablet to other Wi-Fi hotspots. A failed connection indicates a problem with the mobile device. If the connection cannot be made only with a home router, then the problem must be looked for in the equipment used.
What to do when there is a problem with the provider
Solution 1: report the problem to your ISP, replace the Ethernet cable
If there is no internet connection, please report the problem to your service provider. If the breakdown cannot be solved remotely, call the technician home, for example, to replace the Ethernet cable. A reason to think about replacing if you live in an apartment building, and the cable is laid outside. It is important to note that most ISPs have tools to remotely diagnose cable integrity.
Solution 2: check your modem / settings
If the Internet is provided via a telephone line, check that the modem is working properly. Connect the equipment directly to a PC or laptop, check the connection settings. If there is no result, take the modem for diagnostics to the service center.
What to do with router problems
Solution 1: restart your router
A router is a miniature computer, so failures and system errors during operation are inevitable. In this case, the problem is solved by restarting the system. It is advisable to turn off the power supply for 2-3 minutes.
Solution 2: check your internet settings
For the Internet to work correctly, you need to set the correct settings in the management console. This procedure is mandatory if the router is being configured for the first time. The parameters should be rechecked periodically, as failures often lead to a factory reset.
Solution 3: enable distribution of the Internet over the wireless network, DHCP
In the settings, it is important to activate the "wireless router broadcast" and "SSID broadcast" functions. Also enable DHCP, if the option was not activated earlier.
Solution 4: change channel
If a fixed channel is set in the router settings, it is recommended to change the value or set the mode to auto. If the automatic mode is used, restart the router to automatically change to a less loaded channel.
Solution 5: switch the broadcast range
Some routers only allow one or two broadcast bands - 2.4 / 5 GHz. If the frequency range of the router and tablet does not match, the connection will not work. Therefore, set the frequency supported by the tablet in the router settings.
Solution 6: disable blocking by MAC address
Sometimes, when blocking unwanted consumers, it is easy by mistake to add your own tablet to the blacklist, which will prevent you from connecting to a Wi-Fi network. If there are blocked MAC addresses in the list of the router, find out the corresponding value in the Wi-Fi settings. Verify the data and, if necessary, remove the MAC address from the blacklist.
Solution 7: reduce load / temperature
Using a Wi-Fi network will not work if the router is loaded by another connected device - a PC or laptop. Then you need to limit the speed or temporarily stop downloading / uploading information.
Take care of an acceptable temperature regime. If your router is overheating, consider active or passive cooling.
Solution 8: increase transmitter power
If an access point appears and disappears from the list of "available for connection", or after connection is disconnected, the transmitter power is probably muted. Open the router settings and increase the transmitter level. If the antennas of the router are of a removable type, install an amplified version.
Solution 9: reset router settings / update firmware
Sometimes viruses and system crashes do not allow changing settings. When changing the parameters, the values are saved, and after switching to other settings, they return to their original position, which makes the setting meaningless. In this case, it is recommended to set the parameters manually from scratch.
If the reset did not affect the router, then it is worth updating the firmware. If there is no result, take the router in for repair or think about buying a new device.
What to do if there is a problem with the tablet
Solution 1: check if the password you entered is correct
A common mistake when connecting to an access point is an incorrect password. By default, “password hiding” is set in the tablet settings, which makes it easy to make mistakes when entering. Therefore, it is recommended to enable the display of the password, as well as to take into account the case when entering characters.
Solution 2: reboot the system
Sometimes a system failure occurs in the tablet, which prevents it from connecting to the network, or the connection is successful, but there is no Internet access. In this case, restarting the operating system usually helps.
Solution 3: turn off energy saving features
To save energy, most tablets are equipped with power save modes. Usually the effect is achieved by turning off modules that are actively wasting the charge, including Wi-Fi. Therefore, it is recommended to deactivate the corresponding mode or use a productive preset.
Solution 4: change the broadcast range / turn on the display of networks with a weak signal
If the tablet is designed to work with the 2.4 and 5 GHz bands, it is recommended to set the automatic band selection. Also, do not use the option "hide access points with a weak signal", because with a weak signal from the router, it will not be possible to connect.
Solution 5: change firmware / radio module
Often, changing the firmware or radio module helps to improve Wi-Fi performance. If problems with connecting to Wi-Fi started after flashing, it is recommended to return the originally used firmware back.
Solution 6: replace the wifi module / motherboard
If the above methods are ineffective, then the problem will be solved by replacing the motherboard with a working module. In some tablets, the Wi-Fi module is presented as a separate board. Then you do not need to change the motherboard, it is enough to solder the old module and solder a new or used one, but in good condition.
It is often not possible to find a suitable module. In this case, the "implantation" of the USB Wi-Fi module helps, as in the images below. One end of the wire should be soldered to the USB pins, the other to the pins on the motherboard. In the absence of designations near the soldering points, you should first find a diagram.
Conclusion
When using the Internet, the chain of participants consists of three links - a provider, network equipment and a user device - a tablet. To quickly resolve connection problems, it is important to determine in which link the malfunction occurred. The article contains detailed troubleshooting steps if your tablet won't connect to wifi. The solutions are grouped into categories for one-by-one execution, as well as better understanding for beginners and advanced users.
Sometimes the tablet does not see Wi-Fi for a banal reason. It could be a difference in frequencies or cache accumulation in the device. If the tablet does not see your home Wi-Fi network, then first try restarting the device. Usually, an overloaded gadget may simply not connect to the network due to garbage in memory. You do not need to think that if you do not see wi-fi, then the matter is in the quality of the assembly.
The tablet does not see Wi-Fi - the main reasons
There are several main reasons why the machine will not connect to the network. First, we will list them, and then we will analyze each case separately. So the reasons are:
- The difference in frequencies between the modem and the planet;
- Hardware problem - a malfunction in the "hardware" of the tablet;
- The problem is in the settings of the router;
- Software glitch (tablet, modem).
It is not at all necessary that there is only one reason. Sometimes they are combined. But in any case, you should act carefully, excluding possible reasons. If your tablet has stopped seeing Wi-Fi, then first, do a little test. Check if it does not see exactly your router, or any other source too. So you will understand where the fault itself is - in the tablet or in the modem.
Why can't my tablet see Wi-Fi?
We have already written about the difference in frequencies. Please note that the device and source may operate at different frequencies. Specify this point in the parameters. If so, then the question is out of the question. Also, the tablet does not see the Wi-Fi network due to incorrect router settings. You can configure the modem yourself, or contact your provider. As for the software glitch, first try restarting the device and router.
You can read about on the website. If the tablet does not see any Wi-Fi network, then try to get rid of the cache. Restarting often helps. Finally, all the fuss can be caused by problems in the "hardware" of the tablet. So the Wi-Fi unit of the tablet may fail. Oxidation is possible on contacts to the signal receiver. And problems with the antenna are quite possible. If you can work with the tester, then you need to open the device and check the contacts (search for short circuits).
Why doesn't the tablet see Wi-Fi, or sees it but won't connect?
Why does the tablet see Wi-Fi, but does not connect to the Internet? There could be two reasons for this. Different frequencies or a problem with the router settings. The same can be the case if the tablet does not see the operator's network. Now you know why the tablet does not see Wi-Fi. In the next post, we will consider the topic - why the phone stopped seeing wifi networks. There will be questions, ask.
