USB Wifi Adapter - openSUSE Leap 42.3


Hello, I am completely new to Linux. I recenlty installed openSUSE Leap 42.3 in a dual-boot configuration with Windows 10.

I was able to update most of the drivers (video, audio, etc.), but I can't get my USB Wifi Adapter to work.

I'm using ANEWKODI USB 600Mbps Dual Band Wifi Adapater. I've been browsing around some forums and have gotten this far:

I ran the following command, then unplugged the USB adapter and plugged back in:
Code:
linux:~ # sudo journalctl -f

I also ran the following commands after to check how the system recognizes the adapter:

Lastly, I also downloaded this driver:
https://github.com/sloretz/rtl8811au

and followed the README to install, but it didn't seem to change anything.

Not sure what to do next. Help?

It being a realtek device I would suspect that your missing realtek firmware for it.

Although it "didn't change anything", was the install completed or did you get error messages?

Have you run modprobe?

I don't recall seeing any error after running make install. I don't know if running it again has any effect if it's already installed, but I just tried this:

Code:
linux:/home/Metronome/Downloads/rtl8811au-master # make -j 8
make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/4.4.79-19-default/build M=/home/Metronome/Downloads/rtl8811au-master  modules
make[1]: Entering directory '/usr/src/linux-4.4.79-19-obj/x86_64/default'
  Building modules, stage 2.
  MODPOST 1 modules
make[1]: Leaving directory '/usr/src/linux-4.4.79-19-obj/x86_64/default'
linux:/home/Metronome/Downloads/rtl8811au-master # make install
install -p -m 644 8821au.ko  /lib/modules/4.4.79-19-default/kernel/drivers/net/wireless/
/sbin/depmod -a 4.4.79-19-default
I'm unfamiliar with modprobe. What should I be looking for?

modprobe loads a driver/module into the kernel that isn't already loaded. The following will load your 8821au module.
Code:
modprobe 8821au
it maybe
Code:
modprobe rtl8821au

In an effort to assist, I built the 8821au module (via source from github page you linked to), and checked it against the chipset details reported by the journal log
Code:
idVendor=0bda, idProduct=a811
Here's the complete list of chipsets it supports...
Code:
alias:          usb:v0E66p0023d*dc*dsc*dp*ic*isc*ip*in*
alias:          usb:v2001p3318d*dc*dsc*dp*ic*isc*ip*in*

alias:          usb:v0BDAp0823d*dc*dsc*dp*icFFiscFFipFFin*
alias:          usb:v0BDAp0820d*dc*dsc*dp*icFFiscFFipFFin*
alias:          usb:v0BDAp8822d*dc*dsc*dp*ic*isc*ip*in*
alias:          usb:v0BDAp0821d*dc*dsc*dp*ic*isc*ip*in*
alias:          usb:v0BDAp0811d*dc*dsc*dp*ic*isc*ip*in*
I note the vendor ID reported does NOT match yours....
Code:
# modinfo 8821au|grep 811
alias:          usb:v7392pA811d*dc*dsc*dp*ic*isc*ip*in*
alias:          usb:v0BDAp0811d*dc*dsc*dp*ic*isc*ip*in*

Provided the driver is compatible (and loaded),you may get lucky with adding the required chipset details like this (as root)...
Code:
echo '0bda a811' > /sys/bus/usb/drivers/rtl8821au/new_id
Even if this works, and results in a wireless device node being present, it's only temporary measure and will need to be invoked again on next boot.

So I tried colorpurple21859 solution and it successfully loaded 8821au, but the device is still listed as unknown under hwinfo and no entry exists for ifconfig.

I tried ferrari's solution running echo '0bda...' and the entire system crashed. Perhaps I have the wrong driver after all? I guess I'll have to do more digging to find the right one.

And it just occurred to me to ask - how will I know for certain when the firmware is updated? Cause I'm assuming I'll still have to configure the network connection, so there has to be another way to confirm the firmware is up to date. Will the wireless adapter show up under lspci?

Yes, the fact that the chipset was not explicitly listed in the modinfo output is not a good sign. You may need to contact the vendor about this.

The firmware is built-in to the vendor-supplied Realtek driver.

For USB devices use
Code:
lsusb
or

Ok, a bit more searching and I've found the required driver for your chipset (0BDA:A811)...

Code:
git clone https://github.com/scrivy/rtl8812AU_8821AU_linux.git
Code:
cd rtl8812AU_8821AU_linux
Code:
make
Code:
sudo make install
Plug in your USB wireless device and the 'rtl8812au' module should load automatically.

The chipset is listed...
Code:
# modinfo rtl8812au|grep A811
alias:          usb:v0BDApA811d*dc*dsc*dp*ic*isc*ip*in*
alias:          usb:v0BDApA811d*dc*dsc*dp*ic*isc*ip*in*
alias:          usb:v7392pA811d*dc*dsc*dp*ic*isc*ip*in*

So I followed your instructions. The make install command worked (which I assume means the driver was installed). dmesg |grep firmware doesn't return anything, but I did get this:

Code:
linux:/home/Metronome # dmesg |grep wlan

[  191.077538] RTL871X: rtw_ndev_init(wlan0)
and I got this when unplugging the USB and plugging back in:

Code:

So that's new. Still only getting eth0 and lo when running ifconfig (no wlan0).

Now I'm able to bring up my wlan0 in YaST and scan my network. Our wifi SSID (as well as others) show up so the USB adapter must be working. Still haven't figured out how to connect it, but I think I'm most of the way now. Will follow up once I actually have a usable wifi connection.

I did it! So after I got the drivers installed, I accidentally entered the wrong password for our wifi and took some time figuring that out. Once I did, I got connected to the wifi and got it to retrieve an IP address, but it still wouldn't connect to the internet.

After some searching I learned that I had to force my network config to route through wlan0. I did this with the following commands:

[CODE]
linux:/home/Metronome # ifconfig eth0 down
linux:/home/Metronome # route add default gw 192.168.0.1 wlan0
[\CODE]

(192.168.9.1 is our router and my default gateway)

Thank you so much everyone (esp ferrari) for your help and patience. Here's a quick recap of what I had to do to get this working (as best I can remember):

Code:
su
git clone https://github.com/scrivy/rtl8812AU_8821AU_linux.git
cd rtl8812AU_8821AU_linux
make
sudo make install
modprobe rtl8821au
depmod -a
ifconfig eth0 down
route add default gw 192.168.0.1 wlan0
Couple of notes:
- I had to install packages for several commands throughout (make, depmod, git, and I think modprobe). To do this, just type "cnf" and the command you need (such as "cnf git") and your terminal will give you instructions on how to install the package
- You have to have a wired internet connection for some of this to work - namely downloading your drivers. If you don't have one, I assume you'll have to download to a different computer and transfer via USB
- after depmod -a I used YaST to connect my wlan0 interface to our wifi. To do this:
---open YaST
---select Network Settings
---select your wlan0 interface, then Edit
---Set to DHCP, then Next
---Set to Managed, select "Scan Network", select your wifi network from the dropdown, and set your password (mine used WPA-PSK encryption), select Next
Once you've done all this, go back to terminal and proceed with the ifconfig command (see above)

Hope this helps the next person with this problem. Thanks again everyone!

That Module is also included in the Package rtl8812AU_8821AU-kmp-default build by a User in the openSUSE Build Service (OBS):
https://build.opensuse.org/package/s...l8812AU_8821AU

That is an easier way to install it and it will be also updated, when a new kernel is build.

Only 2 Repos to include.
