Problems with assigning SSID and password in MAVLink WiFi bridge

Hello everyone!

I encountered a problem when changing the SSID and password in the MAVLink WiFi bridge. I used the software from ESP8266 wifi telemetry — Copter documentation file firmware-esp12e.bin. From the hardware, I use two modules to which I downloaded the firmware - Cuav Pw-Link and Qiotek. By default, the parameters that I wanted to change have the values ​​SSID - Ardupilot, password - ardupilot. In order to change these parameters to my own, I connected my computer to the network created by the module and went to 192.168.4.1. There, in the Setup tab, I changed these parameters and saved them. After that, I rebooted the module and checked whether the network name and password had changed. I found that they remained unchanged. Then I went into the settings again and reviewed the values ​​​​of these parameters. They remained as I specified. That is, the parameters in the settings have been changed, but in fact they remained as they are provided by Ardupilot. How can I fix this situation and completely change these parameters to my own? What could be the problem?

I would be grateful for the answer!
