Authentication error occurred

[Anonymous]

My Samsung Galaxy 5 connects to the router initially, but after a short period, it disconnects with the message "authentication error occurred." I have re-booted the router and the phone but it still keeps happening. All the other devices in the house work perfectly, including another Samsung mobile. I have deleted and re-added the router information but it still keeps happening. Anyone got any ideas or suggestions.

How short is the "short period"?
An authentication error is usually the wrong password.

usually 10 minutes or so but sometimes a bit longer....wifi password is correct since all other devices connect and work

Have turned the router off and back on again to clear the dns list?
Do you also know what router you have and if it's transmitting on 2.4 or 5ghz?

Hi @Anonymous, please let us know how you're getting on with this?

someone suggested turning the 'flight mode' switch on and then off again. I did this about 36 hours ago and, amazingly - this far anyway - it seems to be working... 🙂

Excellent news and so simple 😀

Was that all you did or anything else?
