|
|
Hi Everyone,
I've got a RealTek USB wifi antenna, and I'm not sure what driver I need for it.
It shows up with lsusb as:
Code: | Bus 001 Device 002: ID 0bda:8172 Realtek Semiconductor Corp. RTL8191SU 802.11n WLAN Adapter |
And I've tried loading the following drivers:
rtl8192se
rtl8192cu
rtl8192ce
rtl8192c_common
rtlwifi
After installing net-wireless/rtl8192su-firmware, but no matter what I try it doesn't show up in ifconfig / iwconfig!
Any ideas? |

net-wireless/rtl8192su-firmware is no longer in Portage because the file rtlwifi/rtl8192cufw.bin from sys-kernel/linux-firmware package replaced it.
Code: |
# emerge linux-firmware
# qlist linux-firmware | grep rtl8192
/lib/firmware/rtlwifi/rtl8192cfwU.bin
/lib/firmware/rtlwifi/rtl8192cfwU_B.bin
/lib/firmware/rtlwifi/rtl8192cfw.bin
/lib/firmware/rtlwifi/rtl8192cufw.bin
/lib/firmware/rtlwifi/rtl8192defw.bin
/lib/firmware/rtlwifi/rtl8192sefw.bin
# cd /usr/src/linux-3.8.4
# grep -r rtl8192cufw.bin drivers/net/*
drivers/net/wireless/rtlwifi/rtl8192cu/sw.c:MODULE_FIRMWARE("rtlwifi/rtl8192cufw.bin");
drivers/net/wireless/rtlwifi/rtl8192cu/sw.c: .fw_name = "rtlwifi/rtl8192cufw.bin",
# grep log_dmesg /etc/conf.d/bootmisc
log_dmesg="YES"
# tail -f /var/log/dmesg
|
As in, follow the dmesg when loading the rtlwifi module and when bringing up the interface(s)
Hope that helps |

Thanks, it looks like I had to unmerge some old firmware to remove blocks, but I got linux-firmware installed now. Rebooted and loaded the rtlwifi and rtl8192cu modules, but unfortunately this is the only line that shows up in dmesg:
Code: | [ 174.790430] usbcore: registered new interface driver rtl8192cu |
Still doesn't show up in ifconfig unfortunately. |

Look at:
Code: |
# cd /usr/src/linux-3.8.4
# grep -r -i 0bda drivers/net/*
# grep -r -i 8172 drivers/net/*
|
And you will find similar ones, but not exactly the one you are looking for. I don't know but looks to me like the newer kernels, with the new rtlwifi driver no longer supports that USB device.
However if you google for 0bda:8172 you will find links like:
https://forums.gentoo.org/viewtopic-p-6945178-highlight-.html
So it seems you might need to go back down to Linux 3.1 to get r8172u or r8172u_usb driver from the staging area, the rtlwifi simply doesn't support your device yet?! Well, I'm done, good luck. |

Hmm, well according to the post you linked to, and one I found the driver is actually 'rtl8712', not 'rtl8172', which is sitting in the staging area. Building that from Linux 3.1 as you suggested, and I'll see what happens when I install it! |
