Set hotspot IP address

Question

I am trying to setup a WiFi hotspot on Ubuntu 16.04. Everything is working, and clients are able to connect to the hotspot.

How do I change the IP address that my hotspot is assigned? Right now, I am assigned 10.42.0.1 but say I want 192.168.0.1 instead.

I tried adding the following to my /etc/network/interfaces file:

auto wlan0
iface wlan0 inet static
address 192.168.0.1
netmask 255.255.255.0

But I am still assigned the same IP address.

Solution

The solution was adding the following line to my hotspot config file /etc/NetworkManager/system-connections/myHotspot in the ipv4 block:

address1=192.168.0.1/24,192.168.0.1

You can change the IP of your hotspot by editing the hotspot config in settings and changing the IPv4 Settings.

The hotspot is likely created using hostapd, so look at the config files for hostapd...

Confirmed working on Kubuntu 16.04. Note after setting IP you need to restart network-manager using sudo systemctl restart network-manager.service.

this solution does not seem to work with 172.16.0.1/24 subnet, which is a valid private subnet..
