I added the linux-wireless mailing list and the other module author (Chaoming 
Li) to this reply.

The first place to check is that /lib/firmware/rtlwifi/rtl8192sefw.bin exists on 
your system. The message you got indicates that the file is not present. If that 
is the case, you can likely get it from your distro, or from the linux-firmware 
git repository.

If the firmware file does exist on your system, then check the md5sum for that 
file. It should be bccf9bf2276621770f101a60736b4004.

Finally, what is the PCI ID for your card as shown by the 'lspci -nn' command? 
That info is missing from your posting.

Please use "reply all" to respond, and do not drop the linux-wireless ML. Unless 
you want to make a deposit to my Paypal account, I do not do private debugging.

On my system running the mainline git kernel (git describe is 
v3.0-rc5-124-g60451cb), I get the following for 'lspci -nnv' run as root:

For 'iwconfig wlan0', I get

The device is generating some warnings in the logs that I need to explore; 
however, it is working.

I have no idea why your device is failing. Perhaps Chaoming will have some ideas 
when he reads this.
