After upgrading the system to V76.0, it is unable to connect to Wi - Fi 6

Hello, after my Quest 3 was upgraded to system v76.0 last night, it was unable to connect to the Wi - Fi 6 (TP - Link TL - 7DR5150) that I had been using. However, it can connect to the 2.4G secondary hotspot of this AP or the hotspot of my mobile phone. It seems that it is unable to connect to Wi - Fi 5 and Wi - Fi 6. Deleting and re - establishing the connection didn't work, and even restoring the factory settings didn't help. May I ask what the problem is?
