It’s half past two in the morning, so the text will be brief - I have almost no strength left. So today, from about lunch until this time, I tried to start, apparently, a WT32 clone. I flashed it relatively easily (considering my further efforts), the access point worked - beauty. But after selecting the network adapter in the WiFi settings - nothing. No reaction from the ethernet port. Needless to say, I tried everything that I found here and on the Internet for more than ten hours - all in vain. Then, to make sure that the port was working, I installed something like “tasmota” - I didn’t really delve into what it was, but it also did not see the port. In the end, I installed ESP easy Mega - and on the tenth try, the lights on the port finally blinked. However, the router still did not see the port.
Conclusion - this is just awful. Everything works fine on WiFi, the signal is stable. But the port was cut off 
It’s a shame.
