 Posted: Sun Aug 19, 2012 5:32 am Post subject: [SOLVED] RTL8188cus Firmware fails to load? |
 |
|
Hello --
I am wondering if anyone has successfully gotten this device working on gentoo:
| Code: | # lsusb
Bus 001 Device 003: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN
|
What I'm getting from dmesg is the following:
| Code: | [ 12.645579] rtl8192ce 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17

[ 12.925261] rtl8192cu:rtl92cu_init_sw_vars():<0-0> Failed to request firmware!
|
but my firmware directory seems to contain the right stuff:
| Code: | # ls /lib/firmware/rtlwifi/
Realtek-Firmware-License.txt rtl8192cfw.bin rtl8192cfwU.bin rtl8192cfwU_B.bin rtl8192defw.bin rtl8192defw_12.bin rtl8192sefw.bin rtl8192sefw.old.bin
# ls /lib/firmware/RTL8192SU/
rtl8192sfw.bin
|
Does anyone have any ideas on how to solve this problem?
Thanks.

evlich,
Is the rtl8192cu driver built into the kernel or a loadable module ?
What shows up in dmesg if you modprobe -r it, then reload it?

That didn't seem to change anything:

I was thinking that this might be related to the fact that I have built-in wireless as well:
| Code: | # lspci
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)
|
The problem is that I think that that device is going bad since I lose my connection to networks all the time when I'm using it. Do I need to disable it in some way and if so, how would I do that?
Thanks. |

evlich,
you should just get two wireless interfaces if bith cards come up. will show that.
I wonder if | Code: | | Failed to request firmware! |
means what it says. That the kernel didn't look.
Please put your kernel .config file onto a pastebin and post the link
---- edit ----
looking at drivers/net/wireless/rtlwifi/rtl8192cu/sw.c, which is where youe error text comes from, it has | Code: | | MODULE_FIRMWARE("rtlwifi/rtl8192cufw.bin"); |
and you don't seem to have that file.
Also the outout of lsusb for your wireless dongle woukld be good.
