 I  am sorry but nothing changed so it still can not be associated.

Well,  I have some interesting observations related to this issue
If I perform soft reboot after rtw88 testing and start wifibox service
( I am using it as backup wifi based on the same wireless adapter ),
then wifibox fails to initialize wireless adapter.  It never happens
if I performing power off /on sequence after rtw88 testing.
 I suspect that rtw88 fails to correctly initialize my wireless
adapter and/or firmware crash

rtw880@pci0:2:0:0:      class=0x028000 rev=0x00 hdr=0x00 vendor=0x10ec
device=0xc821 subvendor=0x1a3b subdevice=0x3040
    vendor     = 'Realtek Semiconductor Co., Ltd.'
    device     = 'RTL8821CE 802.11ac PCIe Wireless Network Adapter'
    class      = network

rtw880: <rtw_8821ce> port 0xd000-0xd0ff mem 0xef100000-0xef10ffff irq
17 at device 0.0 on pci2
rtw880: successfully loaded firmware image 'rtw88/rtw8821c_fw.bin'
rtw880: Firmware version 24.11.0, H2C version 12


Thank you for your hard work
Please let me know how can I debug it further
