The logged VPN user could be recognized by security policy rules.

There's a perfect wizard that automatically generates the L2TP VPN configuration. I used it without making any additional changes, and I believe it should offer the best compatibility across different OS platforms. Phase 1: 3DES/SHA1/DH2 Phase 2: 3DES/SHA1/None

The video streaming buffer (pre-loading) appears to be controlled by the app and browser, and cannot be forced to download the entire video stream.

You may have a check P1 & P2 port setting on switch, and have a try to disable "Management control" function from these ports and make sure if it helps.

If the hostname can be resolved without any issues, then the problem likely originates from Windows Firewall settings, shared folder configurations, or user authentication issues. As a workaround, you can use the IP address to connect to your server (e.g., \\192.168.100.100).

Ensure that the Windows Firewall (or any antivirus software) is set to permit traffic from the destination server. Additionally, it is recommended to initially test the connection using ICMP for diagnostic purposes.

How about connect to local GUI(LAN gateway IP) to re-config your WAN interface.

You might want to try "resize" it. This action appears to be capable of fitting the content to the terminal window. usgflex500h> resize

Is the VPN connection able to establish successfully? You might consider setting up an IKEv2 VPN tunnel using the native Windows client for potentially improved performance. Moreover, deploying the IKEv2 VPN tunnel to each client is significantly easier.

I suggest giving these steps provided by ZyXEL a try. They have been successful for me in upgrading the firmware.

I suggest upgrading the firmware to the latest version as a first step. After the upgrade, carefully monitor the system to determine if the issue still persists.

You may ensure that firmware version on your USG310 is updated and newer than the previous one. This is important as certain commands may not be available in older versions.

I'd suggest trying out the 5.36(ABUI.1) firmware for your device. There have been positive test results reported by users in other threads. It might be beneficial for your case as well.
