Question

I have a problem with the Samsung A7, namely the wifi is disconnected after some time of using the phone (normal browsing and fb), the problem also occurs when the phone is in the sleeper screen, after unlocking you can see the wifi network icon, an exclamation mark at the bottom. Photo attached.
At home, 2 of the same A7s work in the same network.
I changed their names so that they are not similar, they have different IPs and the problem is on both of them the same.

Check available updates for the phone, download if there are any, if there is no backup of the phone content and do factory settings, remember to log out of your Google account, if there is one and / or check what account it is to be able to restore data from Google account.

Check if any energy saving option is enabled on the phone.

RoBsOn87 · Answer

Energy saving is turned off. This is also done when browsing websites.

As for updating or restoring factory settings, it looks like this. The problem occurred from the very beginning, later the system was updated to the new Android version but the problem persisted. I do not know if returning to the factory settings will help, since there was a problem before the last update.
But maybe I am tempted.

Out of stupidity, check the router settings. Maybe she needs a reset.

RoBsOn87 · Answer

Restoring the router to the factory settings did not change anything. Now it only remains to reset the phones, but for this I have to sit down and do some backups.
But it's strange that the problem only occurs on these two A7s at the same time.

Try to change the password to a different one or the encryption mode. In the router itself, also permanently add the MAC addresses of the phones.

GosiaA7 · Answer

I have the same. I don't know what to do, where to rummage anymore. Resetting the phone did not help, changing channels on the router also. I have the settings on the phone for no battery saving, 'forever' settings, changing the card from dual sim 1 to sim 2 also. I am using Netia.

nutergsm · Answer

In that case, go to the service center or take advantage of the warranty.

piotrek08030 · Answer

hi, did you fix this problem? I have a galaxy a40 and the same problem, a netia spot router and I don't know what to do next.

RoBsOn87 · Answer

It just so happens that I have been testing new settings on the netiaspot router for several days and everything is working fine at the moment.
Namely, on NetiaSpot, in wireless connections, do everything automatically, ie Channel, frequency and type of signal.

piotrek08030 · Answer

and you could make a screen where you put it? I only found the channel and changed it to automatic, I don't know where to look for the frequency and type of signal. Added after 11 [minutes]: I looked at your answer from the phone and I did not see any attachments - thanks I changed it as you wrote and will verify if it helped

Tedybear1977 · Answer

you have to check 3 things:

Phone: Try connecting to the Wi-Fi network on another device, such as a laptop or friend's phone. If other devices are using the network, the problem is likely with your phone.
Network: Check if your device can connect to a different Wi-Fi network, such as at a friend's house or a public network. If so, the problem is likely with the network.

Internet: If your device can connect to a Wi-Fi network but can't access the internet, the problem is likely with your internet connection.

Samsung probably has it. For me, when I have to switch to T-mobile, the huawei E5577 router, only samsungs show an exclamation mark and disconnect. Others then work fine. It happens to me when more than 4 devices are connected to the router.

Tedybear1977 · Answer

I had it too, but the fault was on the side of poor data transmission in the router. Only I have a mobile net and there are often speed drops here.
