 |
|
Hi All,
I have a TP Link Archer Ac600 wifi USB dongle. It uses the module RTL8812au.
I used the Debian live CD for installation of Gentoo. In the Live CD I was able to install the drivers using the source code online and DKMS command and it functions post which Gentoo was installed. The Live CD had kernel version 5.0+
After installing gentoo and configuring the kernel (using the same source code) compiled the wifi driver for Gentoo-Sources kernel ver 5.3.9 and 4.19.72 (Stable). In both the module loads perfectly in the kernel.
The lsusb shows the adapter.
ifconfig does not show the device, it just shows lo.
The /dev/ does not show any device named eth0 or enp*
wpa_supplicant shows no adapter
Question) How do I get the device in /dev/ I have tried rebooting the PC many times, plugging / unplugging the adapter etc... Also followed the guide on https://wiki.gentoo.org/wiki/AC1200_Wireless_Adapters
Regards,
Rohit |

| by Using lsmod I could see the modules uploaded to the kernel. |

rsnfunky,
Loading the kernel module is required but not sufficient.
dmesg will be interesting

rsnfunky,
That image isn't very useful. It only shows
That Error Driver 'rtl8812au ... is a worry.
Put the entire dmesg onto a pastebin site. If you don't have any networking, save dmesg to a file.
Reboot with something where networking works. Mount your Gentoo root filesystem an /mnt/gentoo then pastebin the file /mnt/gentoo/dmesg.txt
Its too big for a post.

rsnfunky,
Two or three things.
| Code: | [ 1.757075] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2
[ 1.757191] cfg80211: failed to load regulatory.db |
That may or may not be a bad thing.
If the regulatory.db file does not load, the wifi channels you can use will be seriously limited.
As you have cfg80211 built into the kernel, you should build regulatory.db into the kernel too.
Your WiFi is on the USB bus. Its detected here
| Code: | [ 2.010959] usb 2-1.1: New USB device found, idVendor=2357, idProduct=011e, bcdDevice= 2.00
[ 2.010961] usb 2-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 2.010963] usb 2-1.1: Product: 802.11ac WLAN Adapter |
That's a rtl8812au.
The internet says that it requires firmware. dmesg normally says if its not loaded but your dmesg is silent on the topic.
Do you have the firmware?
You appear to have two drivers for your wifi.
| Code: | [ 10.369574] 8812au: loading out-of-tree module taints kernel.
[ 10.370209] 8812au: module verification failed: signature and/or required key missing - tainting kernel
[ 10.374036] usbcore: registered new interface driver rtl8812au |
and
| Code: | [ 11.988443] RTL871X: module init start
[ 11.988445] RTL871X: rtl8812au v4.3.14_13455.20150212_BTCOEX20150128-51
[ 11.988446] RTL871X: rtl8812au BT-Coex version = BTCOEX20150128-51
[ 11.988456] Error: Driver 'rtl8812au' is already registered, aborting...
[ 11.988458] RTL871X: module init ret=-16 |
They will fight over the hardware and neither will work.
There appears to be no attempt to start the wifi. dmesg should contain associating and authenticating messages, or at least, the attempts.
There is nothing.

good point  The corresponding line from lsusb is
| Code: | | Bus 001 Device 007: ID 2357:0120 TP-Link 802.11ac WLAN Adapter |
I'm using current stable gentoo-sources, i.e., 5.4.72-gentoo |

Thanks for the tips.
I tried this driver
https://github.com/aircrack-ng/rtl8812au
which looks pretty well maintained, and even has an available ebuild
http://gpo.zugaina.org/net-wireless/rtl8812au_aircrack-ng
and set up the kernel following
https://wiki.gentoo.org/wiki/AC1200_Wireless_Adapters#Working_devices
although that's for a different adapter (something is better than nothing).
When I plug in my adapter I see a lot of errors in dmesg, such as
| Code: | WARNING: CPU: 1 PID: 1210 at net/wireless/core.c:414 wiphy_new_nm+0x630/0x6c0

(the error relating the nvidia module and 88XXau is very strange  )
It might be some module missing from the kernel or something entirely different, no idea. Also, I'm getting this ugly errors after enabling some cfg80211-related stuff in the kernel. Before, errors were more along the lines of "symbol some_function_name missing from XXX". |

Just in case someone else stumbles upon this...I got it working: I just had to follow the instructions in the wiki I mentioned above, restart, and, afterwards, emerge rtl8812au_aircrack-ng from the overlay. I'm pretty sure that I tried that before  , but probably missed something important (maybe included in the kernel something instead of compiling as a module...whatever).
About the wiki, my precise adapter is never mentioned there, but the important bit is the driver being rtl8812au. Also, there are a couple of kernel settings that don't seem to exist anymore (I think they were those related to RTL8723AU), but that's fine. |

I am not 100% sure, if this will help, or still is the correct way to do, but here is what I have, and how I got it running:
Bus 001 Device 002: ID 0b05:1853 ASUSTek Computer, Inc. 802.11ac NIC
Needed kernel module: 88XXau
Got from rtl8812au_aircrack-ng from pentoo overlay. |
