You know how to solve my problem?

4

Unfortunately not. I would have given guidance if I knew.

Does COM11 disappear from the IDE and from Windows device manager when you disconnect the board?

Which board do you have and which board did you select in the IDE?

5

yes

6

Everything was working fine but i dont know what is the problem
ESP8266

7

And I tried it from another laptop but still not working

What did you change? Did Windows shove an update down your throat? Did you change wiring or add stuff?

There are hundreds of different boards based on the ESP8266. Please be accurate in the board that you have (post a link if possible) and the board that you have selected in the IDE (there is no entry simply called ESP8266).

From reports I have seen, there appear to be a myriad of possible causes to this issue. So it's not just a "one problem with one solution" situation.

More information is needed from you before anyone will be able to even hazard a guess as to what might be going on. Starting with, as @sterretje has already requested, which board you have and which board is selected in the IDE. Exactly which board in both cases; there are dozens of board types available in the ESP8266 core and countless ESP8266 boards manufactured by numerous companies.

We all look forward to your anticipated cooperation in providing the necessary details. :popcorn:

Take your board out of the setup and try.

Provide a schematic or wiring diagram (with all details); photo of hand drawn is fine.
