Hello!
I disable int. wi-fi but stil working like a client? Screen below. How totally disable this interface?

any info or help?

The simple answer is to click the red "x" in the "Wireless Tables" screen shot. This will disable the wireless interface. What do you want your device to be? You are currently set as a PTP bridge CPE. If you want to be an AP router then just click the Reset Configuration on the Quick Set page. The router will have an IP of 192.168.88.1 and be a DHCP server. The wireless and ports 2-5 will be bridged and port 1 will be a WAN port.

Can You read? Can You see screenshot (wlan1 is disabled)?
Router like new config with Home AP, after that wlan1 disable because wifi is not required. And after You see mode with router actually working, the router itself working like PTP Bridge CPE.
