Computer does not see the access point

The notebook does not measure

Diagnosis of total ignorance of the measure in a large apartment building is simple: around dozens of routers, which can be seen by a functioning laptop. In a private house to test the distribution of Internet via smartphone, creating a point of access.

No available connections

If there is a black cross on the Wi-Fi icon in the toolbar:

Right-click the icon and select “Reset Troubleshooting”. In some cases, the system itself will detect and correct the network error.

This will open a large list where you will need to find “WLAN Autonegotiation” (services are listed alphabetically). Press PKM and move to “Features. Turn on automatic type of connection and reload the computer.

Please note: screenshots are made with Windows 10. They may not look the same on you. Old versions of Windows “WLAN Autonfiguration” is called “WLAN Autonfiguration Service”. Items are signed differently but the path to them is the same.

Dotless Adapter Problems

Make sure the adapter is connected. On laptops, it is activated by pressing the hot buttons, which you may have accidentally pressed. For example, for Asus laptops this is FnF2 connection, and the earlier models have a separate switch.

There are two options here: hot keys and tumbler.

In Windows 10, the icons simply indicate that the adapter does not work or that it is switched off. Fix everything is also simple in a few clicks: click on the icon “Wi-Fi” on the icon of the Internet with the left mouse button.

If the module works, but the laptop is still not aware of Wi-Fi, there is a problem with the adapter.

Go to “Administration” and select “Device Manager. On the list, click on “Media Adapters”. You need the row with the word “Wireless” (“wireless”). Message (sign in the column) indicates that the driver requires updating or is completely absent. Connect your laptop to the Internet via cable, press “Update” button. If there is no cable, you need another device with Internet access. Download the latest driver you found under the name of the driverless adapter, and install it on your computer.

The reason can be in the new driver, which does not work correctly. If this happens, please press on the adapter PKM. Properties. Driver and press the “Select” button. This will bring you to an older but stable version.

  • If the “Select” button is not active, you must uninstall and reinstall the driver. Before deleting, write down the driver version, so that you don’t have to download it again.

Important! Download the Drivers license from the official website of the manufacturer. You can find the drivers you need for the laptop model without the DOT adapter.

If before the laptop ceased to have Wi-Fi coverage, it was cleaned, fell or was exposed to rain, the problem with the adapter may be physical.

Looks like the Wi-Fi module on the picture below. To access it, remove the laptop cover or the keyboard. Unplug the battery, remove the module from the slot. If there is no obvious damage to the dots or pins, put the board back in place and plug the computer in.

If the module still does not show any signs of life, you will have to go to the computer. The cause of the malfunction bezrodrotovy adapters people without experience is difficult to install.

Wtim, doing it is indispensable. You can buy a Wi-Fi adapter with USB connection. It costs from 100-150 UAH, which is cheaper for the service of the mayor to repair the laptop.

What to do if PC can’t see access point, created on pure Android smartphone

Go to “Settings” and go to “Network and Internet”, and from there. to the subsection “Access point and modem.

Select the item “Wi-Fi access point“, and then “Wi-Fi frequency range” (if necessary, expand the additional settings).

After that, check the “2.4 GHz” checkbox and click “Apply”.

It does not connect to Wi-Fi on the phone (iPhone and Android)

If attempts to connect your phone to the available Wi-Fi are unsuccessful, it is necessary to look for the problem in the gadget or in the router. The mobile device in such cases may not see the network, but if it does find it, it does not connect after entering the password.

Authentication problems

If you see the phrase “Authentication error” or “WPA/WPA2 saved” on the screen, most likely the problem is with the wrong password. Otherwise it is worth trying to reboot the router, and if it did not help, then remove the network from the phone memory, and then reconnect to it.

Smartphone can’t get an IP address

This problem is typical only for Android. There can be two reasons: DHCP-server is disabled or Android malfunction. Determining which one is relevant in this case is simple, just try connecting from another mobile device.

If the problem repeats, you must give permission to enable the DHCP server in the router settings. You can find this option in LAN or LAN sections. New settings should be saved. If other phones easily connect to the given Wi-Fi, it is worth trying to reboot your mobile device, the cause of it.

Phone still does not see the network

The cause is most likely in the settings of the Wi-Fi router. If turning off and rebooting does not change the situation, it is worth trying to change the settings of the router. often it helps to change the network channel and region.

You should set static channel and different region in router settings. You may try to set the US region, and if the static channel was previously configured, you should set “Auto”. The failure may not affect other previously connected home devices that are working fine, but the new phone cannot join.

If all the above problems are solved and other phones can easily connect to the desired Wi-Fi, the reason for difficulties may be a problem with the operating system of the gadget. In most cases, the case is limited to rebooting.

Sometimes the problem occurs after replacing the battery, glass or phone case. In this situation you should take your smartphone to the repair shop, perhaps the master forgot to connect the antenna or the Wi-Fi module. Hardware failure of the module cannot be excluded, and it can be also defined and repaired at the repair shop.

Wi-Fi network range as the main cause of the problem

The main reason why the laptop can not see Wi-Fi when distributing from the phone. the unsupported range of the wireless network. The gist of what’s going on is as follows:

  • Many modern phones give out Wi-Fi on 5 GHz by default.
  • Not all laptops and computer Wi-Fi adapters support this range, there is support only for 2.4 GHz.
  • Result. the network is not visible in the list of available networks.

The solution for this case is simple. switch the Wi-Fi sharing on your phone to 2.4 GHz. You can do this as follows:

  • On Android (I give an example for the Samsung Galaxy, but on other Android smartphones the logic should be the same) go to Settings. Connections. Mobile hotspot and modem, click on “Mobile hotspot” and press “Configure”. Under “Preferred Frequency” you will be able to select the desired network range.
  • On iPhone, go to Settings. Modem Mode and turn on “Maximum Compatibility”.

After the steps have been performed, check whether the Wi-Fi network is now displayed on the laptop.

Possible Reasons Why It Can’t Find Wireless Networks

If you know that there are public Wi-Fi networks somewhere nearby, but your laptop can’t see them and therefore can’t connect, make sure that on another device the necessary access points will be detected. If none of the devices equipped with a wireless module see a network, then the problem is in the access points themselves, and not in your laptop. Perhaps the signal is obstructed by walls or other obstacles. these factors should also be checked.

Why can’t the laptop see wireless networks (none)?

But most often the problem is, of course, your wireless adapter is turned off or you don’t have the proper driver. This is what we will look at now.

First, I would suggest just trying to connect your laptop to a wireless network using these instructions. And a separate instruction on how to connect in Windows 10. Perhaps you will succeed, and you do not need to dig into the settings.

Check your wireless adapter driver

If you see a computer connection icon with a red cross on the system tray, then you most likely do not have a driver installed.

To check, we need to go to Device Manager. Open the Start menu, right-click on Computer, and select Manage. In the new window, click on the Device Manager tab. Open Network Adapters, and see if there’s an adapter with the words “Wi-Fi” or “Wireless” in its name. It looks something like this:

If the adapter is not there, you will usually see only one adapter (the network card). it needs to be installed. If it is there, it should be without any icons, like I have in the screenshot above. If there is an icon next to the Wi-Fi adapter, then right click on it and select Engage. Most likely you will have to install the necessary driver. We have a separate installation guide: https://help-WI-FI.com/raznye-sovety-dlya-Windows/kak-ustanovit-drajvera-na-wi-fi-adapter-v-Windows-7/.

If everything is okay with the driver, let’s check if the Wi-Fi is enabled on your computer.

Right-click on the network connection icon, and select Network and Sharing Center. Then, select Change Adapter Settings.

Next, right-click on the adapter Wireless network connection (or Wireless network). and select Enable.

After that, the computer should see wireless networks and you should be able to connect to your Wi-Fi network without any problems.

You may have wireless networking turned off by a keyboard shortcut on your laptop. Check if it is on, as I explained in this article: How to enable Wi-Fi on a Windows 7 laptop? And if you have “10”: How to enable Wi-Fi in Windows 10.

After these actions, everything should work at you. The main thing is that the icon of Wi-Fi network with a yellow star appears, it means that there are networks available for connection.

Causes of possible problems

Many users are often faced with a problem: the phone does not connect to the computer via USB-cable. There are not many reasons for this, and among them we can highlight the following:

To quickly identify the source of the problem, you must take the following steps: observe the change in the Device Manager of your computer when you move the cable near the device connectors or use a different cable; connect your smartphone to another computer; connect the device to each USB port of your computer. The first step must be carefully examine the cable for connecting the computer (tablet or laptop) with the cell phone. If at visual inspection its physical damages are not found, it is necessary to run a tester. On the Internet you can find detailed information on how to do it.

Problems with the phone

Very often such problems occur with Samsung, Lenovo (a319), HTC, LG or Fly devices.

If there is a problem with the phone take the following steps and after each step check the connectivity of the devices:

  • Restart the device.
  • Phone must be set to “USB mass storage mode” (USB device mtp).
  • In settings of the phone to enter into “wireless networks” and to switch on a modem mode (it is possible to find the detailed instruction on how to connect android to the computer through USB on the Internet).
  • Take the battery out of the phone for about 5 minutes and then put it back in.
  • Use USB debugging mode.
  • Scanning with antivirus.
  • Resetting and restoring factory settings.

Personal computer

If no defects detected during cable check, you need to go to computer or laptop problems. In this case there are hardware and software bugs:

  • The driver may be absent or inappropriate for the device model.
  • Defective USB port or port does not support device.
  • Error in the application, which helps to sync the devices.
  • Blocked by antivirus program.
  • Faulty Windows build.

If the driver is missing, it must be installed or reinstalled. For this purpose, you should enter the Device Manager and see if the device is in the hardware list. If it is not there, you need to download the software (driver) and install it. Another way is to manually install from Device Manager:

Double check your computer port requirements, maybe phone just doesn’t support USB 3.0. Must be connected to USB 2.0 and try to flash the phone (you don’t have to flash the phone, because this type of connection has a higher priority than others).

Software for synchronization of two devices can also be the reason of impossibility of connection. To fix this bug you need to download the stable version, removing the old one, and install it. If this does not lead to a positive result, you need to disconnect your computer from the Internet, so that you do not accidentally catch a virus from the network and disable antivirus application.
