WiFi Networking

[RAST]

New Vivobook S 14 S5406 SA on local network with multiple Win 10 computers. When using a USB to Ethernet adapter, all the computers on the network can discover and connect to each other using their computer names (\\ComputerName\Public). When using WiFi on the laptop, the Vivobook can discover and connect to all the Win 10 computers by computer name but the Win 10 computers cannot connect to the Vivobook using the computer name but can ping and connect to the Vivobook using its IP number (\\IPnumber\Public) or Remote Desktop using the IP number. The Vivobook eventually (slow) will appear as a network location in File Explorer on the Win 10 computers but they cannot connect to the Public folders on the Vivobook. The Advanced Sharing options are set correctly with the latest WiFi drivers. The Windows firewall has File and Printer sharing enabled on the private network. All the computers have fixed IP numbers in the router with their computer name. All computers are in the same default Workgroup. This appears to be a WiFi issue on the Vivobook. The router is configured to use WPA2-Personal. If I change the Vivobook to use WPA2-Personal it changes the setting back to WPA3-Personal but shows WPA2-Personal if you look at the WiFi properties.

I am perplexed by how the Win 10 computers can discover (slowly) the Vivobook computer name on the network but cannot connect to it but everything works fine when using a wired connection.

The issue you mentioned seems to be related to network security levels, especially when accessing via wireless network. We recommend checking the firewall and encryption method of your network equipment (router) and conducting step-by-step cross-testing to troubleshoot the problem you are encountering.

Turning off the firewall has no effect. The router doesn't support WPA3-Personal - it is set to WPA2-Personal. The Vivobook allows you to select WPA2-Personal but the selection does not stick (goes back to WPA3-Personal). However, if you look at the network properties, they say it is using WPA2-Personal. Win 10 computers not being able to discover Win 11 computers  on the network seems to be a common problem on Google. All the settings for file sharing are correct and work fine if the Vivobook is using a wired connection. The Vivobook cannot be discovered on the network from a Win 10 computer if it is using WiFi. I suspect this is a Windows problem.
