I'm planning to maybe install Ubuntu server on an old machine. But my question is: can I install Ubuntu server on a machine and have it connect to my home network - wirelessly? I can't use a cable in this case.

this only needs to be done once unless the file gets trashed. (you can put the config anywhere really)
for DHCP just use

should be able to ping your router by ip. $ ping 192.168.1.1

should be done. $ ping google.com
This will not last through a reboot. To make this persist through a reboot,
Add this to the bottom (substitute for wlan0 if you have a different interface):
Note that you might not have the KILLALL component installed if you have a minimal server. You can get killall with:
