Wi-Fi does not work on Android what to do?
If your Android smartphone has stopped catching the Wi-Fi network, in many cases you can fix it yourself. How to find the cause of the problem and restore Wi-Fi, tell us in our article.
Wi-Fi does not work on your phone
There are several options for why a connected Wi-Fi network isn’t working on your phone or tablet. But before you try to fix Android, you need to make sure there are no problems with the internet itself. First, check if it is paid, and second try to connect to the same network with any other device. If the problem occurs there as well, then the problem is in the router or there are errors on the ISP side.
If it does not work on only one device, then perform the following steps one by one. The cause could be a messed up setting, the wrong type of encryption, an invalid date, or a broken Wi-Fi module.

- Feedback from concerned professionals only
- You won’t waste your time dealing with intermediaries
If your iPhone’s Wi-Fi isn’t working, don’t rush to take your device to a service center. Try troubleshooting it yourself first. If you’re having trouble connecting to your wireless network, restart and reset your device. There are also other ways to troubleshoot your Wi-Fi problem that depend on the reason the problem occurred.
- Swipe down from the top of the screen.
- Tap the Wi-Fi icon. and hold it down.
- Check the Use Wi-Fi option.
- Select a network from the list. Networks that require a password to connect to are marked with a lock icon.
Just go to Wi-Fi settings, select the network you want, press and hold (or just press) and select Delete network, or Forget network. Then select the network from the list again, enter the password and try to connect. 2 It is recommended to perform a complete network reset.
Password does not work
Now you have to go into the admin and change the password for the wireless network. Just read and follow the step-by-step instructions in the next chapter. Of course you can connect this way, but it is not a secure connection, and this network is easy to hack.
The reasons why there is no connection to the Internet are few, and they have simple solutions. The main thing is to strictly follow the instructions and do not deviate from it.
All instructions are universal for Android smartphones.
Incorrect Wi-Fi configuration
If WI-FI does not work, you first need to deal with the setting of the access point. For this you need to enter the service menu of the router. On the back of the router there is an address written, which you should enter into your browser.
You should see a screen with administrative data. These are also written on the router and if not, you can try the standard ones below:
Once you have accessed the settings, you need to investigate the parameters:
- Chanel. He is also a channel, which by default is set to “auto”. You can try to change it. If it does not help change it back to previous channel!
- Mode. The default setting is 11bg Mixed. In theory changing it to Only might help.
- Chanel Width. You do not need to change anything, the setting should be set to “auto. Transmit Rate. If there is such an indicator, it is simply worth setting it to maximum.
- Region. In theory, it does not affect anything, but you can try to change it.
If everything is set correctly, but there is no internet on the phone. you can go further.
Wi-Fi password error
Much more common reason. wrong password. It often happens when the key has been changed in the service settings of the router. The phone automatically tries to enter an old password that no longer fits. The solution to the problem. “forget” the access point and reconnect. In this case it’s enough to remember new password set.
Another thing is when the password is simply forgotten. In this case you can view it via a connected computer or smartphone. Here are instructions on how to do it.
Incorrect time or date
Why does not the mobile internet work? Probably wrong date and time are set. The solution to the problem is banal. you need to set the right time zone.
Antitank mines TM-35 and TM-35M (Soviet and Russian mines)
The first domestic production anti-tank mine T-4 was not known for its high performance and reliability. In addition, the country had limited capabilities, which is why the mine never went into mass production. Nevertheless, the need for a new weapon against enemy armored vehicles had not disappeared. As a result, by 1935 the new mine. TM-35. has been developed.
The TM-35 anti-tank mine was adopted for service in 1935 and soon began to arrive in the Red Army engineering units. This product lacked some of the drawbacks of the previous T-4, which paved the way for its use by the Army and allowed it to be actively used up to 1941-42. The main reason of such success can be considered a rather successful (in comparison with the T-4) design, devoid of the drawbacks of the previous development. The experience of T-4 operation was taken into account in creation of the new weapon, which allowed to get rid of some negative features. Nevertheless, the new mine was not without its weaknesses, as it was later learned.
The development of the industry made it possible to equip the TM-35 mine with a metal body. It consisted of a main box and a cover of a characteristic shape, which was a truncated pyramid. The casing of the mine measured 23cm x 22cm, the overall height with the cap in place was 8.5cm. The design called for only one type of hull, so that all the production mines weighed about 5.2 kilograms. A wire handle was provided on one side of the case for easy carrying.

The case of the TM-35 mine was a pressed metal box. On its walls there were protruding teeth that were proposed for use in the final assembly of the mine. The hull lid consisted of a curved top and a plain inner plate. On one side of the box and cover was a hinge to connect it to each other. A hinge made it possible to open the lid to final assembly of the mine before planting.
There was a box with dimensions of 10×2.5×5 cm next to one of the walls of the case. A hole was drilled next to it in the body and fitted with a sliding cover. The inside face of the box had a hole for fuse installation. The main explosive charge was placed around the box in the case. The dimensions of the case allowed the use of six 400 g pieces of explosive and two 200 g pieces. Thus, the total charge of the ammunition weighed 2.8 kilograms. If necessary, the mine could be filled with powdered explosives, but in that case no more than 2.4 kilograms of explosives could be placed in the case. TNT, ammotol, French mixture or other available explosive could be used to hit the target.
Inside the case housing the fuse and associated components were located. The MUV fuse, linked with a fuzing primer (some reports claim the MD-2 primer was used) was placed inside the case through an opening in the front wall. The primer-detonator was fed through an opening in the inner wall of the case and came into contact with one of the explosive shells. Above the fuse was a curved lever suspended on an axle, made of a flat metal plate. It was the fuse that was supposed to be responsible for detonation. In addition, there was a special bolt in the middle part of the cover that made contact with the free (upper) arm of the lever.

The MUV fuse had a fairly simple design. Inside the cylindrical case was a firing spring and firing pin. The last one was pushed out of the case when cocked and secured with a P-check. Additional safety cotter pin was used for safe transport. A thread was provided in the bottom of the fuzing case to receive the primer. The firing pin was to move the firing pin when the pin was removed and ignite the pyrotechnic blend from the primer.
TM-35 mines were shipped to the troops in a disassembled form. Empty casings were carried separately from the propellant caps and fuzes. Final assembly of the mine was performed by sappers before going out on a combat mission. When the mine was prepared for use an eight-pack was placed in the casing or powdered explosive was poured. The mine was then ready for delivery to the installation site.
In addition to the MUV fuse and primer, two special templates were needed to install the TM-35 in order to check the condition of the various parts. One was a long wooden bar, the diameter of which matched the diameter of the 12V fuzing pin. This was used to check the installation position of the primer and primer- primer before installing them, by checking the correct relative position of several parts, including the rocker arm and the socket of the cap in contact with the primer- primer.

The second template was a metal plate with an aperture of the desired size. When setting the mine, the cover should have been opened and the position of the pressure bolt should have been checked. It should not protrude more than the specified distance from the lower part of the cover. In the correct position, the underside of the bolt could touch the free shoulder of the lever, but should not press against it.
After all components had been checked the deminer was to replace the fuse without fuse pin and the primer plug. To achieve this, the cover on the front wall of the mine was slid and the cylindrical parts were gently slid into the ammunition. While setting the fuse, the technician should drive the fuzing cap into the hole in the rear wall of the inner case and place the fuzing cap ring on the pointed end of the arm. The fuse was locked in place with the cap on the wall and returned to its original position.
After all the necessary parts had been assembled, the cover should have been carefully closed and secured in place. To hold the lid in place, several prongs were used on the top edge of the case, which were bent and engaged with the side surface of the lid.
The ready-to-use mine could be placed in a hole of suitable size or on the ground surface. Installation in snow was also possible.
On the principle of the fuse, the TM-35 was little different from the previous T-4. As before, it used a lever that linked the target sensor and fuse. The detonation of the new model was to be carried out by applying pressure of about 120-260 kg to the upper part of the 18×18 cm cover. The cover structure was distorted in this way, with the pressure bolt dropping and pushing on its lever arm. The other end of the lever had to pull the fuse pin, releasing the striker. After removing the linchpin the explosion took place.
The TM-35 anti-tank mine could have a charge of 2.4-2.8 kg. This made it possible to destroy vehicles or armored vehicles. Regular triggering under people was ruled out due to comparatively low sensitivity of the target sensor. Nevertheless, over time, mines with metal casings could also become dangerous to humans. No means of rendering it difficult or impossible to disarm. Even so, the mine could still pose a danger to sappers.
The TM-35 had a metal casing, which affected its longevity. In fact, such a mine could remain in place and wait for the enemy to show up for months or years. Nevertheless, the actual performance of an unsealed munition depended on several factors. Thus a TNT mine might have remained operational for years or decades, whereas an ammonite and other explosives would quickly become damp and lose their effect.
Also of note is the corrosive degradation of the metal parts. The comparatively high triggering force of the TM-35 mine was due to the cover design. If the cover was damaged or destroyed, the force required to crush it was noticeably reduced. Finally it should not be forgotten about the quite sensitive fuse MUV: to extract the pin the force required was not more than 1-3 kg. Thus, with time the TM-35 mine has become dangerous not only for machinery, but also for people.

The TM-35 anti-tank mines were produced in large batches for several years. In the course of mass production at different enterprises various technological modifications were made to the design of this ammunition. At the same time the characteristics of the mines remained at a given level. Production and delivery of the TM-35 mines in its basic configuration continued until 1940. Shortly afterwards a new mine modification called TM-35M was developed and put into production.
The main difference of the upgraded TM-35M from the basic TM-35M was the greater height of the case. By increasing the overall height of the mine to 11.5 cm (while maintaining the other dimensions) it was possible to increase the volume of the casing. An increase in mine height of only 3 centimetres made it possible to increase the internal volume by 1.7 liters and to increase the explosive charge to 4 kg. As before, the mine could be filled with TNT, ammotol, French mixture, etc.д. After modifications the total weight of the ammunition increased to 7 kg. Other characteristics remained unchanged.
The first armed conflict in which TM-35 anti-tank mines were used was the Soviet-Finnish War. In the course of the conflict, it was found that the existing charge of no more than 2.8 kilograms was far from sufficient to defeat the target. In addition, there were certain problems associated with operating metal products in humid climates and during the fall.
Nevertheless, the TM-35’s main problem wasn’t due to insufficient charge or a corrosion-resistant casing. In practice, the proposed way of fitting and laying mines proved to be a serious impediment to the work of the mine clearance squad. Thus the need to equip mine casings with explosive rounds led to a loss of time. The installation of the mines was also a complex and time-consuming process. The complicated manner in which the fuse was set made it impossible to mine near the front line or in the dark. The sappers’ work was also complicated by the high sensitivity of the MUV fuse and the need to place it with the safety pin removed.

Because of these problems, the TM-35 mines could only be laid during daytime and only at some distance from the front line. Thus the quick and stealthy laying of minefields in dangerous areas was almost completely ruled out. As for the lack of power, the low weight of the mine’s own charge was usually compensated for by placing additional explosive sticks next to it.
The TM-35 anti-tank mines had insufficient characteristics and were difficult to handle. This was one of the reasons why their production was stopped during the Soviet-Finnish War. Shortly after this the production of the modernized TM-35M was begun, but only one problem was solved in the new design. insufficient weight of the charge.
From 1935 to 1940 the Soviet industry produced a significant number of TM-35 mines, some of which were used during the war with Finland. Nevertheless, even after the end of that conflict large quantities of such weapons remained in stockpiles. After the beginning of the Great Patriotic War the mines were used again. The available stocks were enough for use until the beginning of 1942. In addition, the improved TM-35M mines were actively used in parallel with the TM-35.
Production of TM-35M anti-tank mines continued during the Great Patriotic War. Such weapons were actively used on all fronts, both independently and in parallel with other mines of similar purpose. With the advent of newer and more advanced mines, the TM-35M is gradually falling out of use. The last munitions of this type, according to various sources, were used in 1944-45. By that time the Red Army already had new models of anti-tank mines, devoid of the drawbacks of the TM-35.

How to Fix Android Phone not connecting to WiFi
Rollback any firmware or Android update
Some of the malware interfere with normal operation of the radio modules. The solution is to scan your gadget with built-in antivirus.
Incorrect router settings
The seventh reason when you get an error when turning on Wi-Fi on Android is incorrect router settings. To fix the problem, you have to go into the router settings. How to do this, you can read in the instruction, which comes with the device. (The algorithm is relevant if there are problems with the home network).
Then select “Wireless Mode Settings” in the control menu. In the line “Channel” should be set to “Auto”, and in the “Mode” line “11 bgn mixed. In the tab “MAC address filtering” must be set to “Off.
Internet access is blocked for a specific reason. Usually you need to adjust the settings or contact your operator to fix the problem, but there are exceptions.
Figuring out why there is no Internet on the phone, you should first check whether you have paid for access to it. After that it is worth to check if the settings are correct, for this purpose look at the top right corner, where the signal stability is displayed. Because it comes from nearby towers, in some cases the phone doesn’t get internet simply because it can’t catch them.
When the signal is weak, it is enough to move a few steps, go to an open space or extend your arm upwards. Also by looking at the connection signals, a person can understand why the Internet does not work on the phone. To the left of the filled scale with the connection (indicated by dashes) the connection type is displayed. When it is EDGE or 2G, most applications will not work because they simply do not have the speed. When there is a wi-fi icon, 3G or 4G restrictions are not set, so all applications work correctly.
Low-speed signal on iPhones and Android phones is due to the fact that the phone does not work Wi-Fi and at the same time the power supply of the tower, which gives out signals, is turned off. This happens when the equipment runs out of battery or some repairs are made. The information is clarified by contacting your local power supply company.
5 Ways to Fix Wi-Fi not Turning on (Works with All Android Devices) Cannot Connect to WiFi
Sometimes Wi-Fi and 3G does not turn on due to problems caused by the provider. In this case, you will need to call the operator and find out what caused the problem.
Tip! If your phone has lost internet, you will not be able to google the number of the operator, so you should write it down in the phone book beforehand.
When the provider can not be reached, the application with the problem is left on the site, but to do this you will need to enter it from another device.
Most often, users are faced with the same reason why the Internet does not work on the phone. it’s all about settings and disabling data transmission. In this regard, it is worth checking the control panel or just pull out the curtain with the settings that are at the top of the screen.
If the first two icons, responsible for 3G and Wi-Fi are lit blue (t. е. They are turned on), but there is no internet, then the problem is something else. On the Android settings check another way: go to settings and select the section with data transfer, then click on the connection to the Internet and check whether the button is lit up blue.
If the settings on the phone were different before and the Internet did not work, then the device is rebooted.
SIM card problems
In the case of 3 and 4G check the correctness of the installed SIM-card. If the problems are related to the work of this part, then calls, SMS, messages in messengers will also be unavailable. It is removed from the device and the contact area is examined for debris or foreign objects.
In some cases the part is wiped separately with alcohol, dried and then reinserted. On older phones (which require removing the battery to remove the SIM) the contacts are wiped with lint-free paper or tissue. If this did not help and there is nothing else to do, then contact the operator for a SIM-card replacement.
Another reason why there is no connection to the Internet is a malfunction of the communication module. This happens because of the mechanical impact on the phone, and it is not necessary to drop it from a great height, sometimes even a simple pressure on the device is enough.
If the Internet does not work because the cable is disconnected, then a person with experience will be able to solve this problem on their own by disassembling the phone and adjusting the position of the part. The problem can also be associated with a failure of the communication module, it occurs through the use of low-quality parts.
Tip! In any of these cases it is better to apply in a service center, instead of trying to disassemble the phone with your own hands.
Sometimes the Internet doesn’t work on your phone only because the device has been infected with malware. This happens when downloading files from pirate sites or surfing the Internet without enabled antivirus. In this case the Wi-Fi does not turn on not only due to viruses, but also due to programs that affect the system files, it happens simply because of developers’ errors.
There are several options on what to do in this situation: delete the last downloaded programs and files or run a full antivirus scan for malware.
If there is no connection to the Internet and it is still unclear why Wi-Fi does not turn on, then you should check the correctness of the router. First they try to go online from another device, if it works, then the technology is fine and the problem is only with the phone. In all other cases check to see if the WLAN light is lit blue (wireless designation).
