GT-BE98 Pro Wireless problem

[SCSG]

Hi everyone. I've a WI-Fi 7 router GT-BE98 Pro running firmware  3.0.0.6.102_34491-ge5d05d6_621-g39ad8_BA08. The router has Smart Connect enabled with 2.4Ghz, 5Ghz, 6Ghz-1 and 6Ghz-2. I've experienced the following problems in the last few days:

1. Out of sudden, the 5Ghz just stopped working. The 5Ghz LED light on the router was OFF.
2. Out of sudden, the Smart Connect SSID just stopped working (2.4Ghz, 5Ghz, 6Ghz-1 and 6Ghz-2 LEF all remained ON). All the clients were unable to see the SSID in the wireless network list.

I had to reboot the router to restore connectivity. Any advice? Thank you.
