Nanopi-Neo problem

Hi all,

I am developing an iot kit based on NanoPi-NEO, but encountering problem on
 using wifi dongle on Neo

1. I use firmware
nanopi-neo-core-qte-sd4g-20160704.img
RTL8188, RT3070, RT5370 could detected by lsusb, but cannot bring wifi up.

2. firmware: 
nanopi-neo-linux-rootfs-core-qte-sd4g-20160804.img
RTL8188 can connect to wifi
RT3070, RT5370 could detected by lsusb, but still no wifi.

However, after I doing "apt-get upgrade", RTL8188 also disappeared in
ifconfig... -_-


I've tried compiled kernel manually

$ make sun8iw7p1smp_defconfig

kernel can compiled successfully. 

But, after I menuconfig
$ make menuconfig 
and add wifi support to kernel, the compilation process failed.
:-(


Does any known how to use wifi dongle on nanopi-neo?

Thanks

Our Debian system has support for popular USB WiFi drivers. Many USB WiFi
modules are plug and play with our system. Here is a list of models we
tested; 

Number Model  
1  RTL8188CUS 802.11n WLAN Adapter  
2  RT2070 Wireless Adapter  
3  RT2870/RT3070 Wireless Adapter  
4  RTL8192CU Wireless Adapter  
5  mi WiFi mt7601  

If you NanoPi M1 is connected to a USB WiFi and is powered up you can log
into M1 and run the following command to check if the USB WiFi is
recognized. If "wlan0" is listed it indicates your USB WiFi has been
recognized: 

ifconfig -aOpen the /etc/wpa_supplicant/wpa_supplicant.conf file and append
the following lines: 

network={
        ssid="YourWiFiESSID"
        psk="YourWiFiPassword"
}The "YourWiFiESSID" and "YourWiFiPassword" need to be replaced with your
actual ESSID and password.
Save, exit and run the following commands to connect to your WiFi router: 

ifdown wlan0
ifup wlan0If your WiFi password has special characters or you don't want
your password saved as plain text you can use "wpa_passphrase" to generate
a psk for your WiFi password. Here is how you can do it: 

wpa_passphrase YourWiFiESSIDFollowing the prompt type in your password and
you will get a new password in the /etc/wpa_supplicant/wpa_supplicant.conf
file. Now you can replace the existing password in the wlan0 file with the
new one.

Hi jjm

Thank you for your reply. 
but, my question is NanoPi-NEO, not then Nanopi-M1


Here is my test result,

on firmware: nanopi-neo-core-qte-sd4g-20160704.img

after insert RTL8188CUS, the kernel report: 

[  93.778099] ehci_irq: highspeed device connect
[  93.790102] ehci_irq: highspeed device connect
[  94.040208] usb 4-1: new high-speed USB device number 2 using sunxi-ehci


# ifconfig -a 
cannot find wlan0,
whether I'd set the configuration files related to wifi/networking or not

configuration files including
/etc/wpa_supplicant/wpa_supplicant.conf， /etc/network/*


# ifdown wlan0
ifdown: interface wlan0 not configured

# ifup wlan0
wpa_supplicant: /sbin/wpa_supplicant daemon failed to start
run-parts: /etc/network/if-pre-up.d/wpasupplicant exited with return code 1
Failed to bring up wlan0.

It looks you used a old image, please try the latest.

Hi Mindee

Which one is the latest image of Nanopi-NEO? How can I download?

Hello,
   They use the same kernel, you can download the latest image from wiki
and reference the above steps to use USB WiFi.
