I cannot duplicate your problem. When I installed the RTL8188EE chip in my 
computer, wifi connected immediately, even before I connected an external antenna.

My configuration is openSUSE Tumbleweed running a 6.1-rc4 kernel. The network is 
controlled by NetworkManager v1.40.2 with wpa_supplicant v2.10-4.
