How to restore the Edimax br 6288 nc router?

Question

network hardware

For some reason I decided to update the firmware, because there was a very old version, but I did not wait long enough after flashing before restarting, or something went wrong. After the second restart, the router seemed to work, but then the wireless network disappeared, connected it with a wire, saw the provider's page on which I was told that the poppy had changed and the offer to save the changes, I agreed. (the old poppy of the router was replaced by a poppy of the laptop). Well, I thought a little. But, having connected the second computer through the wire, I again see the same provider page but with a new poppy (now the second computer). DHCP does not work for the router, I get IP from Provo. and at the same time I can use only one computer (the poppy of which I will save in the settings of the provider).
The web interface does not work, the router does not respond, just do not see it.
YES I KNOW THAT THIS QUESTION WAS AND I SIMPLY COPYED PART FROM IT. Is it possible to restore the router after an unsuccessful flashing? (edimax br-6228nc)
I TRIED THE METHOD WHAT IS DESCRIBED IT DOESN'T WORK.
