BI8DSC Open the x6100, select the u-dig mode, and configure VLAN connection for WiFi in the settings. Then, open the fservice (I think that's what it's called, though I can't remember the first line), and click "Start" in the bottom left corner. Connect your phone to the same WiFi. Open ft8cn, select x6100 and cat mode, network connection, and enter the information set in fs in the pop-up window.
However, if you have high requirements for router performance, a poor-quality router may cause delays. According to the FT8CN manual, it is recommended to use your phone to create a hotspot to avoid delays.
