I have a Thinkpad T430 with a PCIe RTL8188CE. It fails waying I didn’ t load a firmware that doesn’ t exist:

rtwn0: <Realtek RTL8188CE> port 0x4000-0x40ff mem 0xf1c00000-0xf1c03fff at device 0.0 on pci2
rtwn0: r92ce_attach: warning: hardware crypto enabled
rtwn0: MAC/BB RTL8188CE, RF 6052 1T1R
wlan0: Ethernet address: e0:06:e6:c7:54:73
rtwn-rtl8192cfwE_B: could not load firmware image, error 2
rtwn0: failed loadfirmware of file rtwn-rtl8192cfwE_B

I’ve loaded rtwn-rtl8192cfwU_B.ko, never heard of rtwn-rtl8192cfwE_B.ko
