Auto run wifi with static ip

Marcus Nguyen · August 19, 2019

Hello, I am new on the embedded system. I am using Orange Pi zero and I am having stuff with wlan configuration.

I want to run the static ip for wifi on the board and reconnect after every time rebooting

How I do that? I use 2 files below

Quote

etc/network/interfaces

---------------------------

auto eth0

allow-hotplug eth0

iface eth0 inet static

address 192.168.3.100

netmask 255.255.255.0

gateway 192.168.3.1

dns-nameservers 8.8.8.8 8.8.4.4

auto wlan0

allow-hotplug wlan0

iface wlan0 inet manual

wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

iface default inet static

address 192.168.3.111

netmask 255.255.255.0

gateway 192.168.3.1

dns-nameservers 8.8.8.8 8.8.4.4

Quote

etc/wpa_supplicant/wpa_supplicant.conf

------------------------------------------------

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

update_config=1

network={

ssid="myssid"

scan_ssid=1

psk="mypasswork"

}

The eth0 works fine with this setup otherwise the wlan not active even though I used

ifconfig wlan0 up

but I using ifconfig wlan0 down, it got the static ip like the configuration file then I can't turn on or off using ifconfig up/down one more time

Anyone help me?

Thanks a lot!

To create wpa_supplicant.conf use the follwing command and replace only MySSID with your Wifi_SSID

and MyWiFiPassword with the password of your WiFi-Network:

su -c "wpa_passphrase MySSID MyWiFIPassword > /etc/wpa_supplicant/wpa_supplicant.conf"

In /etc/network/interfaces I do use the following config for a wlan0 configuration:

(here you only have to adjust the IP-address and the gateway-IP)

# device wlan0
auto wlan0
allow-hotplug wlan0
iface wlan0 inet static
address 192.168.6.126
netmask 255.255.255.0
gateway 192.168.6.1
dns-nameservers 8.8.8.8 8.8.4.4
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
#  Disable power saving on compatible chipsets (prevents SSH/connection dropouts )
wireless-mode Managed
wireless-power off

This combination does work here since years

The context of your wpa_supplicant.conf should be like something like this:

network={
ssid="MySSID"
#psk="MyWiFIPassword"
psk=eb6934445c268ab6ba6138318e69929b8b68bd6421c679410c01f2ad78fafe21
}

I you know your WiFi password for sure you can delete the bold line with the leading #

I did read in the last years that the uncoded password wouldnt work anymore in some cases.
