S25u Wifi issues

[seo219]

Is anybody having issues with wifi all of a sudden not working and then drops to LTE/5G and you have to manually go to wifi settings to reconnect again? All my other devices stay connected and wifi works so this isn't an issue with my internet. It happens about every hour it's getting really frustrating. I reset network settings, forget network and rejoined, disabled intelligent wifi options, and I wiped cache partition and the issue still persists.

I haven't had wifi issues on this phone with the December security patch, this all started happening with February update.

Samsung members diagnostics says my wifi is normal and nothing unusual.

Possibly check under modes and routines that there isn't something happening in there that is shutting off your wi fi🤔

No issues with WiFi on my S25 Ultra. 

Try the suggestions from @Tallman & @Ray1.

Booting into Recovery & Wiping Cache after every Security Patch OTA is also a good idea.

I've done that and it didnt fix the issue, I think its an issue with the phone switching between 2.4ghz and 5ghz, my other devices do the handoff no problem but this phone has issues, i enabled the tri band (second 5g band back on) to see if the issue goes away, i disabled it because it was a bit slower than the primary 5GHZ band but still worked. If its a band issue its probably software related to one ui 7

My Router is using 2.4 Ghz, 5 Ghz and WiFi 6. No issues.

While it's possible that your issue is related to the update, it's not affecting my S25 Ultra in any way.

What i dislike about such reddit threads is never enough crucial information

Power settings between both bands,
Any hidden or not,
Security settings wpaa2/3 /etc
Type or model or outer or setup of SSID 's just basic info :(

When others chime in w more basic info, it doesn't help anyone isolate the root cause until too many people complain :(

It's not the same as "there's a bug in my food" at a restaurant.
It's more like U"ber overcharged me or double billed me."
OK, what's the amount or date of the charge? How was it paid?
^ "they just charged me too much"
