My phone stops seeing 6ghz SSID's after a few hours. I set up a test dedicated 6ghz (6E) ssid. After I connect to wifi after about an hour all 6E disappear. If I go to search for networks I don't see my test 6ghz (6E) ssid I created. I then went to my computer and it sees the 6ghz ssid and connects fine. I then disabled wifi on my phone and waited 15 seconds. The re enabled wifi and my 6gjz now shows and connects. It does this multiple times a day. I see other here reporting 6E issues also.
If I load a wifi tester that shows all frequency of SSID's, I can see all the 2.4ghz and 5ghz SSID's. Under 6gjz I there is nothing broadcasting it says. If then I restart wifi on the phone, it shows stuff broadcasting on 6ghz.
I have done a reset of all network settings. I also replaced the wifi. It also does not see either of my 6ghz mesh routers. It started with Android 14.
Every other device sees 6ghz fine. Everyone else can connect to the routers 6ghz radio. The Fold 5 is the only device the does this.
It seems like there's an issue with your Galaxy Fold 5's ability to detect and maintain a connection to 6GHz (6E) SSIDs. Despite seeing other frequency SSIDs, it consistently loses visibility of 6GHz networks and requires you to disable and enable Wi-Fi to reconnect. This problem started with Android 14 and doesn't affect other devices, suggesting a device-specific issue with your Galaxy Fold 5. You've already tried resetting network settings and replacing the Wi-Fi hardware, but the problem persists. You've also noticed other users reporting similar 6E connectivity problems with this device.
