Sorry, my typo. The command to run is:

lspci -nn | grep -i net

This is to show the vendor:device IDs.

Thanks. I confirm that you need to rebuild the driver for the 957 kernel. What was built against the 862 kernels is not forward compatible. I suggest you follow the instructions provided by ELRepo:

http://elrepo.org/tiki/wl-kmod

Alternatively, you can try installing ELRepo's kernel-lt that should have the driver, ssb, for the device.

I followed carefully your recommended instructions at http://elrepo.org/tiki/wl-kmod, and it works fine.
I thank you very much for your help.
