On many devices with different Android versions A problem often arises when there is a connection to a WiFi network, but there is no Internet. At the same time, the Internet works fine on other devices connected to the same network. What could be the reason and how to fix this problem.
What can I do to make the Internet via WiFi work on Andorid?
There are several ways to solve this problem:
First way. Most often, the Internet does not work when connected via WiFi on Android due to the fact that it is turned on getting static ip.
To turn it off, go to Settings -> then Wi-Fi Settings-> press the function button that calls extra menu-> in the menu that appears, select “ Additional settings" -> find the item "Use static IP" in the list and turn it off. After that, check if the Internet is working. BUT, this option is suitable for older versions of Android.
If the first method did not solve the problem. Then follow these steps.
Second way. Go to the date and time settings, turn off “Use network time” and “Use network time zone”, then check if the Internet via WiFi is working on your Android device.
Third way. On some Android devices is in WiFi settings The item “Support auto ip (assign an address if there is a dhcp error)”, if you enable it, the Internet via WiFi can also work.
If none of the options helped, write in the comments, ask questions, suggest your options for solving the problem of not working Internet via WiFi on Android.
How often have you needed the Internet on your device, but it let you down and flatly refused to connect to an available Wi-Fi network? If not often, then it happened to everyone once. Today, the RosKeys online store will tell you about the main problems in this area and help you figure out why your phone does not connect to Wi-Fi.
Let's look at the main problems when connecting to wireless network Internet:
the device connects to the Wi-Fi network, but nothing actually loads;
- in the connection status line, the inscription “Connecting...” or “Obtaining an IP address...” does not disappear, and the device itself cannot connect to the network you need;
- authentication error or unchanged status “Authentication...”. As a rule, after this error, the “Disconnected” status appears - and the device does not connect to the Wi-Fi network;
- error “Saved, WPA\WPA2 protection”.
Before proceeding with more complex methods of solving these problems, try the simplest method, known to everyone since the very beginning of the era of high technology - reboot. As the modernized version of the popular proverb says, “Seven troubles - one Reset.” You can also try removing the battery from the smartphone, and then inserting it back and starting the device. It may well happen that the problem will resolve itself.
If these the simplest ways did not give any results, well, proceed to the next steps.
Now we will analyze each error in detail and tell you how to connect Wi-Fi on a tablet or smartphone.
First of all, try rebooting the Wi-Fi distribution source itself - the router. There may be some kind of glitch that can be resolved by rebooting. If this simple step does not bring any results, proceed to further instructions.
Problem solving option No. 1 - changing router settings
Your device has successfully connected to the network, but nothing is loading? The problem may be in setting up the router if this is your first time doing this on your device. Make sure that the router distributes the Internet. To do this, try connecting another gadget to it. If it remains deprived, then you should carefully study the router settings. On the WAN (or Internet connection) tab, check that the specified connection type matches the one provided by your ISP (dynamic IP, static IP, etc.). Depending on the connection type, you should specify additional parameters (password, login, DNS, IP). These settings are also provided by the provider.
It happens that the provider binds to the MAC address of the computer. In this case, after connecting the router, this address does not match - and the Internet does not work. If this is exactly the situation you encounter, connect the router to your PC (the MAC address of which is specified in the settings) directly via network cable. In the router settings, on the WAN tab, click “Clone MAC Address”. Save the settings and reboot the router.
Check that the network/wireless adapter settings are the same as those in the router. Otherwise, a conflict will occur - the Internet will not work. If you did not disable automatic DNS and IP acquisition, then everything should work.
To change settings, open “Network Center” - “Change adapter settings”. If you connect to the router via cable, you can click on “Connect via local network» right click mouse and select "Properties". In the window that opens, you must select “Obtain IP automatically” and “Obtain DNS automatically.” Save the settings.
Problem solving option No. 2 - change the channel
If you used to connect to your Wi-Fi network without problems, but today you suddenly couldn’t do so, try changing the channel. To change it, go to the tab “Wireless network” in the router settings - and select a different channel there(Channel). After saving the changed settings, you should reboot the router and try connecting again. If nothing works the first time, try selecting the next channel and repeating all the steps again.
Problem solving option No. 3 - deleting the connection
Quite simple and often effective method restoring network operation - deleting the connection. To do this, select a network on your smartphone or tablet, click “Delete”, and then try to connect to it again.
Problem solving option No. 4 - password verification
If your device gives you an “Authentication...” error, you should check that the password you entered is correct, as well as your security settings. If you have already entered a password, this item will not appear until you delete it and try to connect to your network again. When reconnecting, please enter your password carefully. If this is still not the case, set the security type to WPA2.
Problem solving option No. 4 - changing the operating mode
When the message “Saved, WPA\WPA2 protection” appears, you should check the speed/operation mode of the wireless network (Wireless) in the router settings, since the smartphone may not always support the router’s operating mode. You need to set the mixed operating mode to auto(b/g/n) instead of n, g or b.
If this method does not help, try changing the encryption type (WPA-PSK, WPA/WPA2). Enter New Password no less than 8 characters. Don’t forget to save the settings and reboot the router, specifying a new password when connecting on your smartphone or tablet.
Problem solving option No. 5 - changing the channel width
You can also try changing the channel width. As a rule, in the settings you can select: Auto, 20 MHz, 40 MHz. Then: Save - Reboot - Check functionality.
Let's look at how to turn a smartphone into a router using an example HTC One V.
First of all, connect Mobile Internet. Then go to settings in the “Wireless connections and networks” section, click on “More”. The “Wireless Networks” window will open, where you will need to select “ Wi-Fi router and a USB modem." In the window that opens, you need to select “Router Settings” and enter the following data:
- router name/SSID - Wi-Fi network name - enter any (in Latin letters);
- security - leave WPA2;
- password - set a password for the Wi-Fi network - from 8 characters (Latin letters and numbers).
All the same parameters must be specified to start the Wi-Fi router, check the box next to “ Mobile Wi-Fi router." After this, an icon will appear on the panel indicating that the router is running. Now your smartphone works as a Wi-Fi router and can distribute the Internet.
It will help you with this special program Virtual Router Plus (or Virtual Router). It will allow you to access the Internet from your device, turning your laptop into a router. Required condition- The PC must be connected to the network via a cable or using a USB modem.
Once the program is installed, enter the following information:
- Name network SSID- give the name of the network that you will distribute;
- password - enter the Wi-Fi password of at least 8 characters;
- general connection - select the type of connection through which your computer is connected to the Internet.
After entering the data, launch the virtual router. You can now connect via Wi-Fi to your network from other devices.
Users often encounter the problem of why their smartphone does not see Wi-Fi. The point here is not in the settings of the smartphone, but in the settings of the router. Carefully check all the settings again and restart both devices. If the data is entered correctly, the network should be detected.
We hope that all our tips helped you connect to the Internet via Wi-Fi - and have a good time wandering the vastness of the World Wide Web.
Wireless Wi-Fi network provides a stable and fast connection. And since most access points distribute the Internet without traffic restrictions, Wi-Fi allows you to download large files for free. But sometimes connect Android smartphone the access point fails or the connection does not work. Why Wi-Fi does not work on an Android phone and how to solve this problem, you will learn in this article.
Reason 1: System failure
The problem is common on undebugged or old Android firmware. For example, yesterday the connection was normal, but today the phone does not display available Wi-Fi networks or freezes during the authentication process.
Usually this problem is solved by rebooting the Android system. If the problem persists and you have previously changed the firmware or communication module, then it is recommended to flash back the standard version of the system or radio module.
Sometimes a system failure occurs in the router. In this case, it is recommended to disconnect the device from the network for 1-2 minutes.
Reason 2: Authentication Error
It’s not uncommon for Wi-Fi on Android to not turn on due to an authentication error. This error occurs when you enter an incorrect password. Moreover, many users forget that the case of letters is also taken into account. Therefore, try to enter the password again, taking into account the case (if the password is in uppercase letters, enter the password in uppercase letters, if in lowercase letters, then write in lowercase letters).
Reason 3: wrong date
Often the date and time get lost after rebooting the smartphone, or when the phone has been turned off for some time. This leads to various errors, for example, a notification about an outdated certificate appears on the Internet every time. Therefore, set the exact date and time, guided by our separate.
Reason 4: interference, channel overloaded
Routers with a broadcast frequency of 2.4 GHz allow you to transmit a signal over a distance of 15-20 meters, with an obstacle of 1-3 walls. In apartment buildings, this leads to air pollution, since they also work at a frequency of 2.4 GHz microwaves and other radio-controlled electronics. Therefore, you should change the channel in the settings if a fixed value is used, or reboot the router if auto mode. After turning on, the router will select a less loaded channel.
Reason 5: incorrect IP address assigned by the router
When connected to a router, the smartphone is provided with an IP address. Sometimes, in order to enable Wi-Fi on your phone, you may need to enter an IP address manually.
Algorithm of actions:
- Open system settings, then Wi-Fi settings.
- Once connected to the access point, press and hold your finger on the access point until a list of commands appears.
- Select the "Change network" option.
- In the advanced settings, change “IP Settings”, “DHCP” to “Custom”.
- Enter the IP address – 192.168.1.3. The last digit is assigned to the router and usually numbers 1 and/or 2 are taken. Save your settings and try again.
Reason 6: Wi-Fi module has failed
Failure Wi-Fi module- a rare event. More often, the module does not work initially, which is found in refurbished smartphones sold in Chinese stores under the guise of new ones. To diagnose the problem, you must contact service center.
Conclusion
Typically, difficulties connecting to a Wi-Fi network on an Android phone are caused by system failures, which can be solved by simply rebooting the smartphone. In rare cases, changing the Android firmware. Problems with the network are possible when flashing the radio module. If the date is set correctly, it is worth rechecking the router settings in case the parameters are incorrect.
One of the most popular questions asked by users wireless internet, sounds like this: “Why doesn’t a laptop running Windows 7 or 10 connect via wifi to the Internet?” Indeed, it often happens that you bought a router, did everything necessary settings. But in the end it turned out that the computer connected to it via cable has a connection and goes online, but the laptop does not see the WiFi network. Or he catches it and even connects, but the Internet on the laptop still doesn’t work. At the same time, Windows writes that there is no access, or the connection is limited or protected. What exactly is the matter and how to fix it? Let's figure it out together!
The Internet via WiFi does not work on the laptop - what is the reason?
First of all, you need to determine the cause of such difficulties. I clarify that the problem is specific to the laptop, since a regular desktop computer most often connects to the router via a cable, or generally gains access to the Internet via a direct connection to the provider. But all the instructions below are also suitable for resolving issues with a large PC, if it has wireless module and the problem being considered today is also present.
It should also be borne in mind that it is not so important which version operating system It has Windows 10, 8 or 7 installed - the guide applies to all. Also, it doesn’t matter what brand the laptop is - most often, Lenovo, HP, Samsung or Asus users present with similar symptoms, but the solution is the same for everyone.
So, all the reasons can be divided into 2 groups:
- Errors on the PC itself, when the laptop does not see wifi initially or just one “fine” day it stopped working
- Reasons related to the wireless network configuration - incorrect settings or the wifi router does not work at all
In order to understand 90% of what type of problem your problem is, just one simple action— try connecting from the same laptop to a different network. If everything is OK, then the problem is with the router. If wifi still does not work, the reason should be looked for in the adapter or the settings of Windows installed on it.
Windows 10 on a laptop does not connect to WiFi due to problems with the adapter
The first group of reasons when a laptop does not see wifi is incorrect configuration of parameters on the computer itself, so let’s try to do something directly in Windows.
Let us note the three most common situations, depending on which the solution to the issue will differ.
- When the laptop does not pick up the wifi network at all,
- when Windows sees the network, but the laptop cannot connect to wifi
- when it connects to a wireless signal, but cannot open pages and says that there is no Internet connection or it is limited
A laptop on Windows 10 says that there is no Internet connection or it is limited
Basically, this set actions should be enough. But if after that it’s still on your Windows laptop 10 does not connect to wifi and writes that there is no access to the Internet or the connection is limited, that is, it is possible to go into the system’s network settings and try to manually set required parameters.
- First, let's try to register a static IP address.
To do this, go to the “Network and Sharing Center” shared access"(to get there, click on "Start - Control Panel - Network and Internet"), where we find the link on the left side "Change adapter settings"
Here we are interested in the line “Default gateway” - this is the IP address of the router, and we will proceed from it when setting the IP address for the laptop. Close the “Information” window and click on the “Properties” button
Here we do double click left click on “IP version 4”
A window will open for entering settings for connecting the laptop to the WiFi network.
- IP for a laptop from the range of addresses specified in the router and available for use. If the router address (the same “Silent Gateway”) is 192.168.1.1, then for the computer you can assign 192.168.1.45, for example.
- Subnet mask - 255.255.255.0
- The router is the IP of the router. On most models, the default address is either 192.168.1.1 or 192.168.0.1 - try them, if that doesn't work, contact your network administrator.
- DNS is also the router’s IP, or you can use one of Google’s public addresses - 8.8.8.8 or 8.8.4.4.
Save with the “OK” button.
- Next step— also manually register DNS servers. This is done in the TCP/IP settings (Control Panel > Network and Internet > Network and Sharing Center > Change adapter settings > Right-click on Wireless connection > Properties > Internet Protocol version 4 (TCP/IPv4))
- Another setting that can help overcome the problem is to go to the “Networks and Internet > Manage Wireless Networks” section in the “Control Panel” on your computer. Find what you need here wireless connection, right-click on it and go to “Properties”.
Here we open the “Security” tab and click on “Advanced options”. Try checking the "Enable Federal Information Processing Standard (FIPS) compliance mode for this network" checkbox. Then save the settings.
This concludes my story about a group of problems that cause errors in the operation of wifi on a laptop related to configuration network settings Windows 7.
WiFi Internet does not work on laptop due to router
Now let's look at cases when a computer or laptop does not connect to wifi due to incorrect network settings on the signal source itself - the router.
The main things you need to pay attention to in the router admin panel are:
- DHCP server
- DNS servers
- WiFi mode
- Geography and date
If WiFi is not working well on your router, first of all try to solve the problem by simply rebooting the router - most issues resolve themselves after this simple action.
If this does not help, the first step is to determine how the network is configured. It often happens that a laptop does not connect to wifi due to the fact that by default it receives network parameters in automatic mode. That is, it is assumed that the router has a DHCP server enabled, which itself distributes individual IP addresses to connected devices.
But for security purposes, it can be configured in such a way that all addresses are assigned manually - either on the laptop itself, or even registered in the network settings in the admin panel of the router itself. A symptom of this problem will be that when the computer connects to wifi networks, the screen will constantly display a message about “obtaining an IP address” without any result.
If you have access to the router, then go to its control panel () and activate the “DHCP Server” in the settings.
Another way is to try manually setting the DNS settings on the router. This is done in the admin panel, in the settings section for connecting to an Internet provider.
This is what it looks like in Asus routers new firmware— “Internet” section, “Connection” tab. Check the box to deactivate automatic selection of DNS servers and provide the following information:
- Or from Google: DNS1 - 8.8.8.8, DNS2 - 8.8.4.4
- Or: DNS1 - 77.88.8.8, DNS2 - leave empty.
In TP-Link routers this setting in the “Network > WAN” section, click the “Advanced” button at the bottom of the page, check the “Use the following DNS servers” checkbox and enter the same values.
Likewise, if WiFi does not work on a laptop connected to a D-Link router (“Basic settings - WAN”)
If after applying these settings and rebooting the router, your WiFi still does not work or your laptop does not connect to it, then let’s pay attention to two more parameters.
- Wireless network operating mode. There are several common WiFi standards that differ in data transfer speed - B (up to 11 Mb/s), G (up to 56 Mb/s) and N (up to 150 Mb/s). If your router is set to the modern “N” standard, and the adapter of the connected device does not support it, then you will not be able to connect to your WiFi. If you are not sure which one is right for you, use “Mixed Mode”
- Another parameter is MTU. It is responsible for the size of a data packet transmitted over the network in one block without dividing it into smaller parts.
In the above screenshot with TP-Link router The default value is clearly visible - 1480. On Asus, you need to scroll down the page in the “Internet” (or WAN) section - we will see the value 1492, which was also the default.
The funny thing is that I took these pictures from routers that were alternately connected to my provider with a PPPoE connection type, that is, for the same different models chose a different value. Moreover, for each type of connection (Dynamic or static IP, L2TP) their firmware contains different meanings. Therefore, to be sure, I would simply recommend calling your provider and finding out what specific MTU values are optimal for your Internet.
And one more setting on the router that may interfere with the adequate operation of Wi-Fi - country, time and date. It would seem like a small thing, but under certain conditions it may also cause wifi to not work on a laptop.
Here are all the methods that I could remember. If you have other solutions to the problem when the laptop does not see WiFi and, as a result, cannot connect to the Internet, share them in the comments!
