I am experiencing problems with my WiFi. It automatically disconnects the WiFi and when I try to connect it shows "couldn't authenticate connection". I tried resetting the whole device and checked any other ones are having this problem. No one is having this issue.

My phone is Samsung M40 (SM-M405F/DS)
Please help me.
