S21 Ultra WiFi Repeatedly Disconnecting

[userJTTyj1Dkbz]

I've reset my router, reset my phone, turned wifi off, turned it on, tried other wifi connections, I've tried turning off mobile data.

I have constant wifi issues, it's always always always disconnecting.

Same Problem, s21 Ultra..  after a while it just turns into connected with no internet. Closing the wifi and opening it again fixes the problem everytime.

So obviously not a router problem.

While that issue hasn't happened to me with my S21 it has happened in the past and the only thing that actually permanently solved the issue was power cycling the router.

I recently bought s21 ultra but the wifi and the regular 5G signals besides the wifi keeps disconnecting even in safe mode. Have tried pretty much everything even the codes, clearing cache and factory resetting the device that includes resetting network settings as well. What else should I do to fix the issue any suggestions??

I was having same problem with my last phone...s21 Ultras so far good connection but definitely has speaker problem

I'd recommend contacting Samsung Support for a possible replacement

I have the same problem as well on my S21 plus. And the same thing just happened to my S10 plus after the Android 11 One UI3 update. It never happened before this. There is something to do with the update that is causing this.

I spoke to the tech team member and I was told to return and place a new order. he also added that issue gets bubbled up if it's happening with majority of customers so the best bet is to return.

Ugh that's such a hassle since mine is a custom color. Those take at least a month to ship.

I know but they don't have the replacement policy for this. I was told by the sales rep she'll let management know to have this kind of system makes things simpler.
