Problem 1: Galaxy S6 won’t remember wifi passwords
Hey guys. So I’m having an issue with the WiFi on my phone. I have an S6 edge plus and have to retype the password every time because it doesn’t seem to remember the password. It does this every time I either turn wifi off and turn it back on or when I’m simply out the house and out of wifi range, if you can help that would be amazing. Thank you. — Gazza
Solution: Hi Gazza. We can’t say with certainty if a cache partition will help since we have no prior useful information about your device but we recommend that you do it to kickoff your troubleshooting. If a cache partition won’t work, that’s the time that you follow it up with factory reset. Below are the steps on how to do each of these procedures.
How to wipe the cache partition of a Galaxy S6
- Turn off the device.
- Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
- When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
- When the Android System Recovery screen appears, release the Volume Up and Home keys.
- Press the Volume Down key to highlight ‘wipe cache partition.’
- Press the Power key to select.
- When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
- Press the Power key to restart the device.
How to factory reset a Galaxy S6
- Turn off your Samsung Galaxy S6 Edge.
- Press and hold the Volume Up, Home and Power keys together.
- When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
- Wait until the Android Recovery Screen appears after about 30 seconds.
- Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
- Press the Vol Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
- After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.
Any of these procedures should help you fix the problem. The cache partition wipe is meant to eliminate possible system cache related problems while factory reset covers almost everything. Remember, sometimes, bad or poorly-coded apps can cause other services and apps from working normally. Be sure to check how your phone remembers wifi passwords right after a factory reset, when there are no apps installed. If the problem remains, it’s probably a networking chip problem and you’re going to need to send the phone in.
However, if wifi works normally after a factory reset but without third apps only, there’s a chance an app is responsible. Try to install your apps again and be ready to uninstall them back one by one if the problem returns. Keep in mind that there’s no way to pinpoint which app is causing it. You’ll have to use the process of elimination to identify it.
Problem 2: Galaxy S6 can’t connect to one wifi network only
When trying to connect to the Wi-Fi it always brings up the internet for authentication and then says error page can’t be found. If I press advanced and then keep connection it says I’m connected to the Wi-Fi but I’m not. It works when I’m connecting somewhere like a store or Starbucks. Those still take me to the internet but there is a page to connect there. — Sami
Solution: Hi Sami. If your phone is having trouble connecting to the internet via one particular wifi network only, that means that you either have:
- incorrect credentials (wifi username and/or password), or
- your device is not authorized to connect.
Be sure to talk to the administrator of the wifi network you’re having a problem with so they can give you the correct username and password or allow your device to connect.
If you’re having a problem with your own wifi network and you’re the sole network administrator, which means there’s no one else who knows how to configure the router, be sure to contact your internet service provider (the company that provides your internet/wifi).
Problem 3: Galaxy S6 mobile data is extremely slow
Hello! I have a Galaxy S6. My issue is my data is EXTREMELY slow (and sometimes doesn’t work at all) when I’m not connected to wifi. Can’t get online, can’t play games or open apps. What usually happens is it times out and just says site can not be reached. It’s pretty frustrating and at times I’ve found myself out and about and needing a number to a company and I’ll have to text a friend and have them look it up and text it to me.
I have T-Mobile thru Walmart’s My Family Plan option. I recently received text messages from them saying they were updating their network to a newer 4G LTE service and that unless you upgrade your phone you will experience slower speeds if you do not currently have a phone that is a 4G LTE phone. I’m under the impression that my Galaxy phone is 4G LTE. I’ve talked to them about it only to receive no help.
I’ve done a lot of research and I am currently considering switching carriers, but I would like to keep my phone. I love this phone. It does everything I need it to and I have no reason (and can’t afford!) to get a new phone. So is there any way you can tell me if it is something related to my phone or is it my provider???
I don’t want to switch providers if it is my phone because then I’ll still experience the same problem. Any help is appreciated! Thank You! (I don’t know what my “Android Version” is, how can I find that out?) — Anthony Miller
Solution: Hi Anthony. There are two types of connectivity options that you can use to connect to the internet — mobile data (from your carrier) and wifi. Since you obviously have a mobile data connection problem, the first thing that you should do is to ensure that you select the fastest available network available — 4G/LTE. To do that, you need to head over to Settings>Connections>Mobile networks. If you’ve already selected 4G/LTE before contacting us, then it’s possible that there’s an on-going problem with the network. To see if that’s the case, insert your SIM to another compatible device and see if mobile data works just fine. If mobile data connection, even when 4G LTE is selected, is still slow, that’s an indication that there’s a network problem. In that case, you should go ahead with your plan to switch carriers since it’s not a phone issue at all.
Problem 4: Galaxy S6 won’t connect to any wifi network
Hello. I have a Samsung Galaxy S6. It won’t connect to wifi anywhere. Not at home, work or my parents house. It says it’s connected or saved and secure but then scans again and I have to switch it to 4G. I have forgotten and reconnected the wifi, put it in “safe mode,” rebooted my router and done a factory reset. I also was going to try the W.P.S. button on my router, but Fios doesn’t have one. Besides, it isn’t connecting anywhere, not just at home. Of course when I brought it into the Sprint store, it connected right away there so the guy didn’t know what I was talking about. Any suggestions before I throw it into oncoming traffic? — Jalxa
Solution: Hi Jalxa. You have an interesting case here. If you are 100% positive that the phone did connect to the wifi network of the Sprint store you went to and to the internet, that means that the hardware (networking chip) is working. The phone is probably having a problem connecting to wifi networks it connected to before. Do another round of factory reset via Recovery Mode and see if the phone can connect to any wifi network when there are no apps installed. We think one of the apps you downloaded is causing the problem. We can’t say this for sure though so if the problem persists after doing our suggestion, consider getting a replacement phone to resolve the issue.
