had the same issue on my a52s. definitely it's the a52s issue, it cannot access the gateway router 192.168.0.1
i have to turn the a52s wifi off and on to reconnect. stupid issue, should file a bug to samsung to fix it.
I have the same problem with my A52s and think it is the worst phone I've had. Only 14 months old and the wifi button is faded out to light blue! I have tried all the suggestions and even done a factory reset and reinstalled apps reentered passwords and still doesn't work! Not sure what the guarantee covers either but the most expensive phone ever bought
I have the same problem tried everything and is not my network, tried with 2 different modems changed dns and the same problem connected without internet then connect but I have a masive packet lost, checkednother devices connected to my network and is normal, when I do the speed test from cloudflare website using my A52 cellphone ahow a 80% packet lost if I try another cellphone packet lost is 0% tried everything remove network, reset network settings, reset cellphone 3 times, tried 5 different networks and still the same mesaage connected without internet but all my other devices work fine, the only way to not have problems with the connection is using mobile data, hope they can see this thread and find a fix because I alredy tried all the basics an no solution.
