WROOM-02D disconnect problem

Hello
Until now, we have been used the WROOM-02 module. This module works with all access points without any problems, but now we want to use WROOM-02D. If we use WROOM-02D, this module, when connected to the network via some access points, is repeatedly disconnected from the network and does not reconnect to the network until it is reconfigured with AT commands (but the module is reconnected to the network as soon as it is reconfigured). The same module works with some other access points without any problems. Note that we use a separate processor and AT commands to data communication with the module, and the AT commands to both modules WROOM-02 and WROOM-02D are exactly the same
We have purchased a large number of WROOM-02D modules and have encountered this problem. Please help us in this regard

Best regards

Maybe you could have a try with command "AT+RESTORE" to factory reset it first, and then connect it to an access point.
