Title: Need help with USB WIFI Adapter on ROC-RK3323-CC...

I have spent many hours and am extremely frustrated. I installed image "ROC-RK3328-CC_Debian9-Arch64_20180525.img" on a new Renegade board and plugged in a compatible USB Wireless adapter "Ralink Technology, Corp. MT7601U Wireless Adapter" but when I run 'ifconfig -a' or 'iwconfig' I am only showing lo and eth0.

Everything looks right, can anyone help what I am missing???
apt-get install firmware-misc-nonfree (installed)
lsusb

Any guidance would be appreciated, thanks!

The OS's are experimental at this point. It is possible it is broken. Try updating through wired connection, it may fix things. If that doesn't do it, try a different OS. I'm using Arrmbian booting off external HD on the USB 3.0 (very fast!). It's not perfect eg (video choppy, and wont run Kodi yet) Can't tell you if if wi/fi works thorough. I never use it. Wired is healthier for you and,faster. I'm not connected to this site so, you my get better advice but, I see lots of unanswered posts here though.

I had luck using the image on here

[url=]http://share.loverpi.com/board/libre-computer-project/libre-computer-board-roc-rk3328-cc/image/ubuntu/[/url]

that wifi will work out of the box.

The problem with video acceleration still persists though.

Hi!
Sorry for opening this post again, but I still have this problem. I tried with the image perello left there, but no `wlan` in ifconfig or anything else.
I read in another forum which drivers are already installed in ubuntu images (http://forum.loverpi.com/discuss ... 4-114-linux-headers) , and I bought a wifi dongle with a RTL8811AU chip, with no luck at all.

How have you managed to solve it?
I am completely lost...

Sorry again

What's the kernel message when you plug in the wifi dongle?

What's the kernel message when you plug in the wifi dongle?

This is the message for the RTL8811AU wifi dongle:
dmesg

[ 7919.892530] usb 4-1: new high-speed USB device number 3 using xhci-hcd
[ 7920.005845] usb 4-1: New USB device found, idVendor=0bda, idProduct=c811

[ 7920.005873] usb 4-1: SerialNumber: 123456

I also installed the package rtl8812au-dkms, but the result it was the same as before:

```
firefly@firefly:~$ lsmod

firefly@firefly:~$ iwconfig
lo       no wireless extensions.

eth0    no wireless extensions.

firefly@firefly:~$
```

For the TP-Link WIFI (chipset MT7610u) the message is the following:

```
[ 8803.151433] usb 4-1: new high-speed USB device number 4 using xhci-hcd
[ 8803.264833] usb 4-1: New USB device found, idVendor=2357, idProduct=011e

[ 8803.264861] usb 4-1: SerialNumber: 00e04c000001
```

With the same result as the previous one

Thanks in advance

It turns out that RTL8812AU is supported out of box, and NOT RTL8811AU.

We do not have RTL8811AU at our hands. However, when looking up
Windows drivers, both RTL8812AU and RTL8811AU use the same one:

https://www.realtek.com/zh-tw/co ... /rtl8812au-software
https://www.realtek.com/zh-tw/co ... /rtl8811au-software

After installing the Windows driver, the RTL8812AU dongle is recognized as
RTL8811AU.

Maybe, you can try to add the vid/pid to
kernel/drivers/net/wireless/rockchip_wlan/rtl8812au/os_dep/linux/usb_intf.c

and try it yourself.

Thank you very much for your help.

But I am afraid a noob in terms of modifying kernels.
What should I do exactly? Do I have to download a clean ubuntu image and then compile the kernel manually like the instructions of the webpage you have posted? But how can I add the drivers there?

Sorry

We're gonna to buy the RTL8811AU dongle. Please be patient.

Hard to get the right dongle. We buy the stated RTL8812AU dongle, but its VID/PID is:

Bus 002 Device 002: ID 0bda:0811 Realtek Semiconductor Corp.

Copy the code

Never mind. We managed to add your dongle's 0bda:c811 to the kernel module
to see if it works for you.

Plz following these steps below:

1. Download 8812au.zip from attachment

8812au.zip (445.09 KB, Down times: 18)

2. Extract 8812au.ko from 8812au.zip

3. Copy 8812au.ko to the board

4. Move the kernel module to the system path:

sudo cp 8812au.ko /lib/modules/4.4.114/kernel/drivers/net/wireless/rockchip_wlan/rtl8812au/
sudo depmod -a

Copy the code

5. Check module installation by:

grep C811 /lib/modules/4.4.114/modules.alias
# should return:
# alias usb:v0BDApC811d*dc*dsc*dp*ic*isc*ip*in* 8812au

Copy the code

6. Reboot your board to take effect.

sudo reboot

Copy the code
