What should I do if my Wi-Fi does not turn on?

Read an article about how Wi-Fi doesn’t turn on

TIPS: Make sure your case is closed.

What should I do if I am connected to WiFi but cannot access the Internet?

Restarting the unit 1 to 3 times may solve this problem. Otherwise, read WIFI but no Internet or try a full reboot.

Turn off the Android device by pressing

  • Activating airplane mode
  • Press and hold the power button for 7 seconds – to turn the phone off.
  • Remove the battery (3-5 minutes).
  • Press and hold the power button for 1 to 2 minutes
  • Replace the battery and turn the camera on
  • After 2 minutes, try to connect to Wi-Fi. Make sure flight mode is off.

What should I do if the Wi-Fi connection of my Galaxy phone is too slow?

Slow connections can be very annoying. None of us use a Wi-Fi connection that makes us wait too long when it comes to opening websites or watching videos. Many ISPs blame this problem on peak times, when many people connect to Wi-Fi at the same time. This is due to Wi-Fi channels where most users are on the same Wi-Fi channel at the same time.

An easy way to solve such a problem is to use the Wi-Fi Analyzer application. It is available in the Google Play Store and is relatively easy to download and install. It analyzes the network and helps you determine which channel is best for you.

Slow WiFi issues are very noticeable with the Galaxy series, especially with the Samsung galaxy s5.

  1. See Decisions 18, 17, 16 and 13.
  2. Most users have solved the problem by updating the firmware on their device or modem.
  3. In most cases, a simple reboot of the router is sufficient. You can try to perform a hardware reset of the modem. Most modems work this way:
  • Press and hold the reset button for 10 seconds. Some modems require you to use a pin and push it in with some force.
  • Unplug the modem and wait at least 5 minutes.
  • Reload

If you try to connect to the modem from a remote location or behind discrete walls, it will not work. Note that these are radio waves propagating along a uniform and straight path. If two or more walls are blocking you, there may be interference with your waves.

Another solution for slow Wi-Fi

1. Download the DNS SET
application. 2. Go to wifi and forget your current wifi
3. Select your current WIFI and restart
. 4. Open the DNS SET application and select AUTO-RUN.

Why is my Android reporting a Wi-Fi authentication error?

What does the verification problem mean?

If you get the message wifi authentication error occurred, it simply means that the network configuration of your Android device doesn’t match or doesn’t match the router’s network. This could be

  • You have entered the wrong password.
  • Incorrect SSID (Service Set Identifier – Wi-Fi network name)
  • Authentication or filtering by MAC address
  • Unauthorized wireless security (WPA/WPA2/AES, TKIP)
  • Incorrect radio mode (802.11a/b/g/n)
  • Wrong channels
  • Dynamic Host Configuration Protocol (DHCP)
  • Network address translation (NAT)

To solve these problems with wireless authentication

  1. Check the Wi-Fi password. Make sure Wi-Fi is visible when you connect to reduce possible errors.
  2. In most cases, your router will have a default SSID name, for example. B. Linksys, Netgear. If you have more than two networks with the same SSID, this can cause problems. On the other hand, some ISPs recommend not changing the SSID, as this can lead to authentication errors and other Wi-Fi-related problems. It is best to reset the SSID name to the default and consider using a similar name.
  3.  Consider enabling or disabling Mac address filtering in the router settings to limit access to the Wi-Fi network by Mac addresses. If this feature is enabled, make sure your address is enabled.
  4. Make sure you have the correct wireless security settings (WPA/WPA2) ETC. These are special forms of authentication and encryption defined by your ISP. They provide a degree of security and confidentiality. Try one or the other and see what works best for you. You can also use applications such as Fix Wifi and Wifi App.
  5. Switching from one radio mode to another. 5 GHz or 2.4 GHz. 802.11a/b/g/n is the standard for most wireless communication networks.
  6. Channel switching can not only speed up Wi-Fi, but also reduce interference, authentication failures, and IP address conflicts. If you download the WLAN application, you can easily change the channel or do it in the backend of your router.

A simple solution to the Wi-Fi authentication error:

  • Go to Wi-Fi settings and turn on airplane mode.
  • Go back to the Wi-Fi settings, tap the preferred network, and then tap Forget This Network.
  • Switching between flight modes disabled
  • Reconnect to the Wi-Fi network, (check the password again).

What to do if your WiFi still does not connect or cannot get an IP address?

  • Change the IP settings of the router. To do this, follow the instructions: Settings > Wi-Fi > Edit > Show Advanced Options, and then change the IP settings to Static.
  • Find the MAC address of the S5 in Wi-fi > Settings > Advanced and check if this address is present in your router. It is best to disable MAC filtering.
  • If the channel is very congested, the Wi-Fi speed will be affected. So try to go on a less crowded channel.
