Step 11: STA : Assign DHCP IP address |
Step 11: AP : Assign DHCP IP address |
Attention This initiates DORA. Make sure DHCP server is running in AP ! |
Attention odhcpd and dnsmasq needs to be installed to setup DHCP server |
Note udhcpc is DHCP client |
Note See below ! Add configuration in /etc/dhcp/dhcpd.conf |
Note udhcpc -i wlan0 gets IP address from DHCP server |
Note See below ! Add configuration in /etc/default/odhcpd and dnsmasq |
# Release any existing IP address
$ ifconfig wlan0 0.0.0.0 up
# Run DHCP client on wlan0. This initiates DORA
$ udhcpc -i wlan0
