AFAIK, it is not critical (at least for USB devices).

If it won't work without firmware try to install it from
sys/modules/rtwnfw/rtwnrtl8192cEB (and restart the interface).

Hi everyone,

rtwn(4), urtwn(4) and urtwm (from previous emails) drivers were merged into a
single rtwn driver (plus rtwn_usb / rtwn_pci device glue); the code is
available on repository. Among bugfixes /
code deduplication, there some new features too:

1) multi-vap support (one any wireless interface + one STA interface +
any number of monitor mode interfaces).
2) few new sysctls:
* dev.rtwn.#.crypto - controls how to use hardware crypto acceleration
* dev.rtwn.#.ratectl_selected
* dev.rtwn.#.ratectl - selects current 'rate control' algorithm
(currently only 'none' and 'net80211' are supported; RTL8192CE needs testing
with the last).
3) (incomplete) power management support for RTL8188EU (requires firmware).
4) Short Guard Interval support.

It's known to work with RTL8188CUS, RTL8188EU and RTL8821AU; however,
it was never tested with RTL8192CE or RTL8812AU.

1) download / checkout the repository.
2) apply 'patch-usbdevs.diff' against '/usr/src'
3) build and install rtwn module:
 cd $repository/sys/modules/rtwn && make && make install
4) build and install rtwn_usb/rtwn_pci:
 cd ../rtwn_usb && make && make install
 cd ../rtwn_pci && make && make install
5) unload previous && load current drivers:
 kldunload if_urtwn if_rtwn
kldload /boot/modules/if_rtwn.ko /boot/modules/if_rtwn_usb.ko /boot/modules/if_rtwn_pci.ko
6) Use.

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
