Only the GS308 series loses connection from the Wi-Fi router
When I connect a Sony Wi-Fi router(NSD-G1000T) to Port 1 of a GS308 series switch, it receives an IP address from the DHCP server and functions as a switch for the first 3-5 seconds.
My PC con...

That (STP) setting (default: ON) was the cause of this issue!
I didn't fully understand STP, so I couldn't fully utilize your comments.Thank you again for following up.
I wanted VLAN functionality, but it seems I was buying a device beyond my level of knowledge. I need to learn more about the device I purchased (GS308T).

Thank you for your advice.
I confirmed the setting of the GS308T.
I had proceeded factory reset at the previous investigation procedures, and the confirmed setting: the loop protection setting was OFF.
I also confirmed the settings of the Sony router, but I could not find sittings regarding these loop protection/detection functions.
I am still having issues, but I appreciate your support.

Again a totally different beast. That's why the community does always request the exact device make and model.
These GS308T (might) have Spanning Tree Protocol (STP) enabled by default - as these are standard for business and enterprise class networking devices - something these kind of Easy Mesh and similar are simply highly incompatible (just like the Loop Prevention the GS308E does have) to these wonderful Mesh **** - albeit always calming it's IEEE compliant. All makers of these wonderful MEsh systems don't tell the uneducated customers that only so called "unmanaged" switches can be used - the reasons are Loop Prevention and even more STP. These systems do -not- accept the same MAC address appearing on different switch ports or networks.
Ensure STP (RSTP) et all (like the Loop Prevention) are disabled, and try again.

The cause only. The effective issue(s) is (or are) these unlucky IEEE Mesh "standards" which are basically incompatible with industry standard network and their configurations. Note: No serious network admin does operate a LAN without STP, RSTP, MSTP - such networks don't exist in reality.
And to make it even worse, the designers and marketers of these wonderful Mesh network s**t don't tell the average
innocent users that their wonderful Mesh "designs" (IEEE 802.11s) come with massive interoperability issues with -real- networks built following industry standard network design rules.
The real issue is this:
802.11s extends the IEEE 802.11 MAC standard by defining an architecture and protocol that supports both broadcast/multicast and unicast delivery using "radio-aware metrics over self-configuring multi-hop topologies."
Sounds to good th be true - and works -only- in combination with "dumb" switches, or probably one day switches compatible to IEEE 802.11s....
This "standard" seriously allows the same MAC address to appear on multiple ports 8-))) Serious network designers do -never- allow this. So equally, STP, RST, MSTP do -not- ... never!
One might find some notes or in some community forums like ours here, that these Mesh systems require "unmanaged" switches. Truth is that these Mesh designs can work on networks without STP, RSTP, or the Netgear (and Realtek == RTK) Loop Prevention. Now one could disable these features on many managed or smart managed switches luckily.
