Solution 1: Toggle your Wi-Fi
Whether you cannot connect at all or your Wi-Fi connection keeps dropping, toggling the Wi-Fi connection is known to be effective in many cases. Pull down the notifications area of your phone and look for the Wi-Fi icon, tap on it to switch it Off, wait for five seconds and turn it On again. Allow the phone to look for the available Wi-Fi connections and check if your problem is fixed. This simple trick is effective no matter which model you have. It fixed Samsung Galaxy S2 Wi-Fi issues, but it also solved Samsung Galaxy S7 Edge Wi-Fi problems for quite a few users.
Solution 2: Toggle the Airplane Mode
This is a fix that has worked for many users, so try toggling the Airplane. You can look for Airplane Mode in the notifications area of your Samsung Galaxy phone, for those who do not find it, you can tap on the icon which allows you to check all the icons of the notification area and look for Airplane Mode. Switch it Off, wait for five seconds and Switch it On again.
Solution 3: Is Your Phone’s Bluetooth On?
The Bluetooth can create a conflict for the Wi-Fi because some users have noticed that on certain phones when the Bluetooth is switched On, the Wi-Fi does not work. If your Android Smartphone Bluetooth is On then switch it Off from the notifications area and then try to use your Wi-Fi again to check if the problem is fixed.
Solution 4: The Power Saving Mode
The power saving mode is meant to help your battery consume less power. Since the Wi-Fi is known to drain the battery quickly, when you switch on the Power Saving mode, it usually disconnects your Wi-Fi. Make sure Power Saving Mode is Off. You can Access Power Saving Mode from the Settings menu of your Samsung Galaxy phone.
Many Samsung Galaxy S3 users had reported an issue that the Samsung Galaxy won’t connect to Wi-Fi disabled saying it was because of poor connection. It was found that when the phone returned from sleep mode, the power saving mode interfered with the Wi-Fi and it somehow interrupted the connection. The problem was in the software so users had to ensure that Power Saving Mode was switched Off if they wanted to use a stable Wi-Fi connection.
Check if the Power Saving Mode is creating a conflict in your phone so that you can fix the Wi-Fi problem on your Samsung Galaxy device or any other Android device.
Solution 5: Forget All Wi-Fi Networks and Start Again
A useful method in solving Wi-Fi problems, especially when you are unable to connect to a network is to delete all networks so that your phone’s Wi-Fi gets a fresh start. But before you decide to proceed, make sure you have all the details you need to reconnect to your Wi-Fi network. This will include the network name and the password needed to connect to the network.
- Go to the Settings menu of your phone
- Tap on Connection
- Look for Wi-Fi and tap on it
- All Wi-Fi networks that you have added to your phone will be listed here. Tap on each of the network names and tap on Forget.
Now that the networks are deleted, you must add the network you want to connect to by going into the Settings and tapping on Wi-Fi and then Wi-Fi network. Here you will find the network you want to connect to, tap on it, enter the password and you should be able to connect.

Solution 6: All about Passwords
Passwords are inevitably important because they are meant to secure the network from unauthorized access and if you end up entering the wrong password, you will not be able to establish a connection. While you may know the password, there is a possibility that you are entering it incorrectly. Check if you are entering the letters correctly and whether you have caps lock on your phone On or not. A Samsung Galaxy S3 Wi-Fi authentication error occurred when customers tried to connect to a network which used WPA2 but the problem was resolved with the help of updates.
Solution 7: Are you connecting to the right network?
More often than not, you may notice several networks that have similar names. Make sure you connect to the right network or else you will not be able to able to establish the connection.
Solution 8: Smart Network Switch
Certain Samsung Galaxy phones come with the Smart Network Switch feature which means that if the Wi-Fi connection is unstable, your phone will automatically switch to mobile data and use the mobile data connection. While it makes it easy for us to forget problems related to the Wi-Fi, if you do not want to use your mobile data connection, then switch it Off. Many users who complained about the Samsung Galaxy S5 keeps dropping Wi-Fi signal, found this to be a helpful solution.

Solution 10: OS Update
Operating systems must be updated regularly. Your android phone will work better when the software of your phone is updated in a timely manner. Your phone’s Wi-Fi may not be working because of a bug in the software. When a company is aware of a bug, they release fixes in the updates. When the Samsung Galaxy S3 was trending, one of the most common problems faced by its users was that their Samsung Galaxy S3 Can Connect to Wi-Fi but No internet.

This can help you solve the problem of a dropping connection when the Wi-Fi ended up disconnecting because your phone went to sleep mode. It is helpful for many Android users who did not realize that their sleep mode settings were intervening with their Wi-Fi connection.
Solution 12: Restart Your Modem
If all the devices connected to the modem are not working, then it is advisable to restart your modem. To do this, you must follow the manual that came along with the modem. Depending on the model and type of modem you are using, you may have to follow different steps. Restarting the modem helps solve Wi-Fi connection issues arising from problems in the modem.
If you notice that restarting the modem – (Read how to restart modem at WikiHow.com) did not fix the problem, check if you can connect to the network and use Wi-Fi from another device using the same modem. If all other devices are able to connect and use the connection without problems then you can continue troubleshooting your phone.
On the other hand, if none of the devices are able to connect, you will be required to troubleshoot your modem. For this, you can either call the modem manufacturers or follow the instructions mentioned in the manual that came along with the modem.
Solution 13: Third Party App
Certain third party applications can be causing a conflict which does not allow the Wi-Fi to work as expected. Check if you recently downloaded an app since the time you began facing the problem. If you did so, then you must check if the app is updated. If it is updated and it is possible that the problem is arising from the app, then uninstall or disable the app and try using the Wi-Fi connection once again.
When one of our readers complained that their Samsung Galaxy S4 Wi-Fi won’t turn on, he followed a number of troubleshooting steps before realizing that it was a third party app that was causing the problem. If you want to check whether a third-party app is causing the problem or not, then switch on your phone in Safe Mode.
- Press and hold the Power button
- Next, tap and hold Power Off
- You will be asked if you want to reboot to safe mode
- Tao OK
- Your device will boot into Safe mode
- Your home screen should have the words Safe Mode written at the bottom left of the screen.
Try using your phone in Safe Mode and check if the Wi-Fi connection works without problems. If it does then a third party may be causing the problem. You can then restart your phone the usual way to enter normal mode and then check for updates for your apps. If all the apps are updated but the problem continues, you may want to uninstall apps that you think may be causing the problem till your Wi-Fi works properly.
Solution 14: Check Your Wireless Router Settings
When my android phone won’t connect to Wi-Fi, I usually consider checking the settings of the wireless router – (Read official guide from linksys.com), I use as well, because I may have dabbled with the settings and ended up blocking my phone from connecting to the Wi-Fi. Make sure that your phone is allowed to access the Wi-Fi and its Mac Address is not blocked or else you will not be able to connect to the Wireless router.

What to do if the Wi-Fi connection on my Galaxy phone is too slow?
Slow connections can be very annoying. None of us enjoy a Wi-Fi connection that makes us wait too long when it comes to opening the websites or watching a video. Many providers blame it on the peak hours when numerous people are connecting to Wi-Fi at the same time. This is caused by Wi-Fi channels where most of the users are on the same Wi-Fi channel at the same time.
An easy way to resolve a problem like this is by using Wi-Fi Analyzer app. It is available on the Google Play Store and downloading and installing the app is relatively easy. It will analyze the network and will help you check which channel will be best for you.
Slow WiFi problems are very prominent with the Galaxy series, especially the Samsung Galaxy s5.
- View solution 18 ,17 , 16 and 13
- Most people solved the issue by updating their device or the modem firmware
- Most cases, you just need a simple router restart. You may attempt to do a hard restart of the modem.Most modem operates like this :
- Press and hold the reset button for 10 seconds. For some modems, you’ll need to use a needle and insert inside a little hold.
- Unplug the modem from the outlet and wait for at least 5 mins.
If you are trying to connect to the modem from a remote location or behind discrete walls, it will not work. Note that it is all about radio waves that travel in a uniform/ straight path. If two or more walls are blocking you, then that can cause interference with your waves.

Why did my Android say Wi-Fi authentication error occurred problem ?
What does authentication problem mean ?
When you received the “wifi authentication error occurred” message that simple means the network configuration of your android device does not coincide or matches with the network of the router. This can be
- You have entered the wrong password
- Incorrect SSID (service set identifier -Wi-Fi network name)
- MAC address authentication or filtering
- Incorrect wireless security (WPA/WPA2/AES,TKIP)
- Incorrect radio Mode (802.11a/b/g/n)
- Incorrect Channels
- Dynamic Host Configuration Protocol (DHCP)
- Network address translation (NAT)
How to fix these authentication wifi problems
- Double check your Wi-Fi password. Make sure wifi is visible while entering to limit any mistake possible.
- In most cases, your router will have a default SSID name, such as Linksys, Netgear. If you have more than two networks with the same SSID, it may cause problems.On the other hand, some ISP recommends not to change the SSID, it can cause authentication error and other wi-fi issues. The best thing to do is to reset the SSID name to default and consider not sharing a similar name.
- Within your router settings, consider turning this to “Off or disabled” Mac address filtering can restrict Mac addresses to connect to a Wi-Fi network. If this feature is on, double check to see if your address is enabled.
- Make sure you have the right Wireless security settings, (WPA/WPA2) ETC. These are special types of authentication and encryption placed by your ISP. These provide some levels of security and privacy.Consider trying between these and see which one works best for you. You can also use apps such as Fix Wifi and the Wifi App
- Toggle between the Radio mode. 5 GHZz OR 2.4 GHz. 802.11a/b/g/n is a standard setting for the most wireless communication network.
- Changing the channel can not only make your Wi-Fi faster but it will also limit interference, authentication errors and IP conflict issues.By downloading the Wi-fi app you can easily change your channel, or it can be done within you router backend.

What if your WiFi is still not connecting or cannot obtain IP address?
- Changing the IP Settings of the router. For that follow the steps: Settings >Wi-fi > Edit > Show Advanced Options and then change the IP Settings to Static.
- Find the S5 MAC address from Wi-fi > Settings > Advanced and make sure that this address is present on your router. It is better to switch off the MAC filtering.
- If the channel is very crowded, then the impact will be on the speed of Wi-fi. So try to jump to a less busy channel.
What to do if Android Wi-Fi won’t turn on?

AT&T D850. I did all this and it’s still happening. I did a factory reset. OTA update for Marshmallow. Still happening. It’s completely haywire. It will “see” networks in the area…maybe 8…then it will see only one…then nothing…then 6…then 2. If you find one and hit “Connect” it will either just completely drop it and not even “see” it anymore…or just revert to “saved”. sometimes I’ll get it to connect to a desired network…then ten seconds later…gone. Or it will be fine for five minutes…and as soon as I go to do something…pass data for an app or email…dead. I’ve spent probably over 20 hours at this point trying to come to grips with this and what I realize is this phone is going in the landfill…for this one “small” hardware issue…the whole phone is by-and-large now useless. Everything was fine for two years…suddenly one day-wifi is haywire. So completely frustrating. Never another LG.. Never.
