S23 Ultra - Connect to WiFi but no internet/constantly dropping out/Wifi6 issue

[Chistery]

Anyone else seeing issues with Wifi6 on their S23 Ultra?

My phone will connect but then stop passing data until I disconnect and reconnect. The same SSID is fine on my S22 Ultra and all my other devices. I have tried to reset the network connections and all that, but keeps happening.

Changing to my 2.4Ghz SSID is fine, but a lot slower.

I've been experiencing the same issue. However, based on the latest trend online I tried adjust my Wi-Fi settings to turn off 802.11ax and its been holding well for the longest time now (more than 3hrs). Previously I would be happy if I could stay connected for 3mins

Yes mine does it constantly, no mobile signal and no WiFi and videos constantly buffering. Not happy after spending alot on this phone

Same for me but cannot find workaround apart from turning phone off and then back on.

Issue is definitely a bug with WiFi 6. Since turning off WiFi 6 on my router no more dropped connections. This is not a long term fix and hopefully Samsung **bleep** out a permit solution soon.

Just disable AX signal in router for temp solution.

I was suffering frequent disconnections on my S23, until I decided to split WiFi6 and 2.4 in separate SSIDs. I've then connected my S23 in the now pure Wifi6 network, and it's working for days.

Give it a try.

Tried the same thing I perhaps..? I'm just not into all these IT stuffs, but it does work for me so far for couple of hours and still working fine. Attached a screen shot of what I done to the setting in the router. Basically changed the setting to BGN mixed ONLY(Circled in red works for me). Not anything to do AX. Hope it does work as long. Before this, the connections works for few mins each time which was really frustrating😅

I am having issues with 5Gbz wifi. I have two 5Ghz wifi in my home, it will connect to one, but the other one says "Connected without internet" and all the other devices in my home can use that one just fine its a problem only with my S23 Ultra.  I am afraid to exchange my phone, as the screen is fine, I'm scared if I exchange it I'll end up getting one that has a screen issue. Is it likely this issue can be fixed with a software update? I had no idea my phone was not connected to the wifi and I've totally blown my data cap this month and being charged extra by my carrier as I do not have an unlimited data plan.

Still no luck for my S23U with WiFi6 after March Update.

All other Samsung Phones are working just fine in my WiFi 6 WLAN Network.

I tried a dozen of WiFi 6 combinations in the setup of my professional LANCOM LX6402.

WPA2 – WPA3
Bandwidth 20MHz-160MHz

Only 2,4GHz or combined 2,4+5

After some minutes or some hours the WiFi 6 starts freezing on the S23U.

I was forced to switch back to WiFi 5.

I haven't been offered the March update yet, but I was honestly hoping they would of held back and included this fix with that update.  Pretty concerning they didn't do that, I can't believe they are having this big of a problem providing a hotfix for this.  The only way I was able to resolve the issue was disabling wifi 6.
