I've just installed ubuntu server 17.10. During installation, it suggested me to connect to the network through wifi, and so i did. After installation was finished and system was rebooted, computer connected to the wifi automatically (which means, it saved the connection creds somewhere). But in
/etc/network/interfaces i found nothing. I need my computer connect to wifi network with static ip, so I've put configuration into the
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8) # Generated by debian-installer. # The loopback interface auto lo iface lo inet loopback iface wlp2s0b1 inet static wpa-driver wext address 192.168.0.12 netmask 255.255.255.0 gateway 192.168.0.1 wpa-ssid ***** wpa-psk ********** dns-nameservers 220.127.116.11 192.168.0.1 auto wlp2s0b1
When system starts, it doesn't connect using my configuration. It does only after
sudo ifdown wlp2s0b1 && sudo ifup -v wlp2s0b1
and after this command, system getting a SECOND IP! Server is still available by the ip it gets from DHCP, and in the same time, it is available by the static ip!
