Creating a Static IP With wlan0

I am trying to figure out how to create a static IP address for my Ubuntu server. So far, I have scoured the internet and have only found how to do it with eth0, when I am using a PCI adapter for my main send/receive. This may not be as efficient as Ethernet, but this is simply for learning web structure, if you will.

Is there a difference between setup for wlan0 and eth0 static IP? If not, can I be referred to a site that explains how to do this in the fullest manner?

Thank you.

Solution 1:

The short answer is yes, do it the same way. By the time wlan0 is working (which is generally the tricky part in Linux), it is being treated the same as eth0 and you can use identical directives to configure wlan0 however you wish.

EDIT: Instructions

Open /etc/network/interfaces using your favorite text editor (I use vim):

vim /etc/networking/interfaces

It will look something like this:

auto lo
iface lo inet loopback
auto wlan0
iface wlan0 inet dhcp

Make it look like this instead (using your own values for address, netmask, etc):

auto lo
iface lo inet loopback
iface wlan0 inet static
address 192.168.1.100
netmask 255.255.255.0
network 192.168.1.0
broadcast 192.168.1.255
gateway 192.168.1.1

Bring down the interface (simplest way to release DHCP IP):

ifdown wlan0

Bring it back up (simplest way to effect new setting):

ifup wlan0

Here is a decent write up.

It's pretty likely you don't need the ndiswrapper part of this. That is only useful if you need to pull the windows drivers to make your nic work.

Solution 3:

Although, static ip for LAN is straight forward, I found trouble finding instructions for static ip for wifi Following works on Debian 10 (Year 2020), even in text only mode, or with ssh-ed system

• connect with LAN
• connect internet
• apt install network-manager (this will install nmtui)
• nmtui
• set static ip for your wifi, save, exit, restart
