Hi,

I've just tested this scenario using an Archer C64 with the same firmware version 1.13.2 Build 230824 and SSH connected fine via Wi-Fi connection.

Can you ping the other computer via the Wi-Fi connection? If not, then verify that you have not configured "AP Isolation" or "Device Isolation" on your Archer C6.
 

  @woozle I'm able to ping wifi host and wired host. AP isolation and Device isolation are both disabled.
An exemple of a try of connection

Can you please crosscheck this issue with another client device connected to the Wi-Fi of the C6?

If you don't have another computer available, there are also SSH client apps available for Android and iOS devices.
