Dear Linux folks,


Using Debian sid/unstable with Linux 6.1-rc3 [1] on an Intel Haswell 
Haier laptop with a RTL8188EE, I am unable to connect to a wireless network.

     $ sudo lspci -k -s 08:00.0
     08:00.0 Network controller: Realtek Semiconductor Co., Ltd. 
RTL8188EE Wireless Network Adapter (rev 01)
     	Subsystem: AzureWave RTL8188EE Wireless Network Adapter
     	Kernel driver in use: rtl8188ee
     	Kernel modules: rtl8188ee

It’d be really great to get WLAN working on the device.


Kind regards,
