Why is my home WiFi constantly getting an exclamation mark and stopping.

[KennyBS1]

Apologies if answered elsewhere, just don't know what to search for.

I connect to my home WiFi and it works like normal. Randomly the internet just stops and an exclamation mark shows next to the wifi symbol and says no internet. I need to disconnect and reconnect and it works until it happens again randomly. (it can work anytime in between 5 mins and an hour)

My partners device/my firestick/laptop all are connected with not a problem but this keeps happening to my phone and only on my home WiFi.

How can I fix this as extremley frustrating when watching or playing games and it disconnects?

Any help is appreciated

Have you tried re booting the router? Another thing to try is on your phone select forget your home WiFi router then re connect with your WiFi password.

There's nothing wrong with the router if other devices get internet connections. But if forgetting the connection and putting it in again doesn't help, there may be something wrong with the phone and you'd have to bring it to a repair shop to get it fixed. (Intermittent limited connections are almost unheard of - either the phone connects and gets a full connection, it connects and gets a limited connection or it doesn't connect. Bouncing in and out of a full connection would mean something like the phone's "idea" of the gateway address keeps dropping. And that would mean bad eMMC storage.)

I have reset the phone back to factory settings and still happens. Would this need to go to a Samsung repair shop or any local mobile phone repair shop?

I know Rukbat said it won't be the router as other devices work okay.

I had a similar problem where my phone and TV worked fine but my Samsung tablet would intermittently disconnect, replacing the router solved the problem. Before you send your phone for repair check the phone on a friend's WiFi just to confirm that the fault is with the phone.

Check the settings on the router for the number of devices allowed to connect.
By default, the number is usually 255 or something like that, but for security reasons someone may have lowered that number so that new devices are now competing for not enough slots.
