Using Ubuntu 19.04 I am trying to connect to an ad-hoc network with my Wi-Fi card (wlo1) and use ethernet (eno2) for access to the internet. The ethernet internet connection works fine on it's own. In order to connect to the Ad-Hoc network my /etc/network/interfaces file is as follows:

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

auto wlo1
iface wlo1 inet static
    wireless-mode ad-hoc
    wireless-channel 1
    wireless-essid AdhocSSID
    address 192.168.1.2
    netmask 255.255.255.0

Now with the interfaces file like this I can access the Ad-Hoc network correctly, but I can no longer access the internet with ethernet. This is the output of ifconfig for the interfaces file above, which suggests to me that the ethernet connection still works somewhat:

Any suggestions?

EDIT: I solved my problem by using Ad-Hoc ip addresses in the range 169.254.x.x rather than 192.168.1.x
