How do I set up a wireless connection after install Ubuntu Server 15.10? (systemd) [duplicate]

  • 772

I tried lshw -C network and my wireless interface says DISABLED.

How do I re-enable it and connect it to the available wireless network?

It's an Intel 3945ABG and it worked fine in the installer to download the updates etc.

  1. DISABLED often means that the wireless switch or button is set to turn the wireless radio off. You can check this from the terminal:

    rfkill list all

    Hard blocked:yes indicates that the wireless is blocked by the hardware switch or button. Find it and change it.

    To set up the wireless in a server, I suggest you set up /etc/network/interfaces something like:

    auto lo
iface lo inet loopback

auto wlp3s0
iface wlp3s0 inet static
address 192.168.1.150
netmask 255.255.255.0
gateway 192.168.1.1
wpa-ssid <your_router>
wpa-psk <your_wpa_key>
dns-nameservers 8.8.8.8 192.168.1.1

    Be sure to select a static address outside the range used by the DHCP server in the router, switch or other access point. Of course, substitute your details here. Confirm that your wireless interface is wlp3s0 with the terminal command:

    iwconfig

    Get the system to read and use the changes:

    sudo ifdown wlp3s0 && sudo ifup -v wlp3s0

    Did you connect?

    ping -c3 192.168.1.1
ping -c3 www.ubuntu.com
