Why doesn't Google Play work on wifi?

Question

Google

Actually, the problem appeared after the firmware of the device. Google Play stopped connecting via wifi, but via 3G everything is fine. I've tried the known solutions and they didn't help.
- The date is correct.
- the hosts file was difficult to open and everything slowed down wildly, deleted it, wrote down 127.0.0.1 localhost, nothing has changed.
- cleaned the cache, installed other firmware, rolled back to the factory ones - the same thing.
- deleted Google updates, set gapps - result 0.
- Changed DNS to Google, wifi point works fine.
Perhaps I missed an efficient way? Tell me who knows.

Answer 1

1. The router hangs - try to restart it
2. The problem is in the provider to which the router is connected.
3. Check the access rules - maybe someone denied access with a rule on the router...

Answer 2

try to log in through the operator's network.

Answer 3

And what kind of device, Samsung?
Is there internet on the gadget at all?
Maybe there is a limitation of the router on the number of connected devices.
Try changing your router's security settings
Have you checked with another router?
Can I install applications through the Google Play website?
Set the device to the correct time and check again.
