If you register without Wi-Fi - it works fine. But if I add WiFi

waiting for network configuration

waiting an additional 60 seconds for network configuration

It takes a long time to load, but eventually it loads. Network is working, Wi-Fi is not. When I connect the cable, I can connect to the computer via the network address 192.168.1.38 (wlan0), but if the wire is disconnected, it is no longer possible ...

You have two interfaces with static addresses from the same subnet, and all packets to the local network will go through one of them, see the routing table.
Better merge p1p1 and wlan0 into bridge and give it one common address

There is also NetworkManager. It is pumped enough at the moment, it even knows how to VLAN out of the box. There is a graphical interface, there is a console utility for configuration. And Wi-Fi is configured in two clicks, as it should be.
Why didn't NetworkManager suit you?
