S24U trouble connecting on 5GHz WiFi

Greetings all. Been having an issue with my freshly arrived S24 Ultra which is doing my head in and was wondering if anyone else is having the same issue and/or knows of a fix.

At home, I have a number of 2.4Ghz and 5Ghz SSIDs. Some combined, some not. For whatever reason, it seems the S24U will not connect to the 5GHz one(s). I can see it automatically tries a number of times (maybe 3-4) to connect and eventually I get a message that "connection has failed". I've tried absolutely everything:

* Factory reset S24U
* Restart router/access point (I have a Unifi Dream Machine Pro & U6-LR)
* Update firmware on both Router & AP
* Switch between 2.4Ghz, 5Ghz and combined SSIDs. S24U will only connect when it's 2.4Ghz
* Try WPA3 + 5Ghz (didn't work)
* Disable all SSIDs and leave only 1 at 5Ghz
* Enabled WiFi Safe-mode in Developer Options

I've dumped the logs as well but couldn't make much sense of them. One interesting line was: "Connect <mac address> <SSID> is FAILURE. cmid 0xc000003 reason 8 status 65529 (google yields nothing)

I've had S9, Note 10+, S22U, S23U with no issues. Nothing from the above helped with the S24U though. Appreciate the help. Thanks in advance

I'm having the same problems with mine. I am with vodafone and have a router that supports 2.4Ghz, 5Ghz, and 6Ghz, but whatever I do, the phone will only connect for 1 minute and the disconnect again.

Same here. I can only connect to 2.4g while tab s9+ has no issue.

Sorted it - found a Google solution. Go into WiFi menu and intelligent WiFi and switch 'Turn WiFi on/off automatically to off. Then try and connect. I connected it fine. Then toggled it back on.

Mine seems to stay on the 5Ghz SSID. I'm with Virgin with their latest Hub (the one for the 1Gbps fiber). Both SSIDs have the same name. Screenshot_20240131_235030_Settings_1000016230_1706745030.png

Maybe play around with the Connectivity Labs, there's quite a lot of info and diagnostics.
