 I am glad to inform that now my rtw88 is successfully connecting to
2.4 Ghz network

wlan2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=0
        ether 80:91:33:4b:4a:d1
        inet 192.168.0.41 netmask 0xffffff00 broadcast 192.168.0.255
        groups: wlan
        ssid .... channel 11 (2462 MHz 11g) bssid a8:5e:45:47:0d:b8

It was limited to connect to 5 Ghz networks before your latest changes today

My wifi device PCI info:

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

It was running for a few hours today without any issues. I will update
my report if something wrong happens during the next 2-3 days but now
it looks promising

Thank you for your hard work.
