Wired connection and ad-hoc wireless at the same time

I'm setting up an Ubuntu Server 14.04 with a wired connection (p4p1) and creating an ad-hoc wireless network. Here's my interfaces file:

# The loopback network interface

auto lo

iface lo inet loopback



# The primary network interface

auto p4p1

iface p4p1 inet dhcp



# WiFi

auto wlan0

iface wlan0 inet dhcp

wireless-mode ad-hoc

wireless-channel 4

wireless-essid Augmented Learning

wireless-key 1234567890

address 192.168.0.2

netmask 255.255.255.0

broadcast 192.168.0.255

gateway 192.168.0.2

Things are running smooth when one of the two interface is up, but when both are up, I can neither access Internet (via p4p1) nor access my ad-hoc network (with wlan0).

What should I do to run them both at the same time ? I don't need to share the connection.

Thanks,

One thing you should not do is point the gateway to your own IP. The gateway tells the system how to route to any IP address not in any of the subnets to which it is directly connected. Normally this is the route to "the Internet", so should not be present for a connection to an internal network unless the route to the Internet is on a host on that network. So remove the gateway line from your definition of wlan0.

There may be multiple things wrong here, so this might not be the only change needed to fix your problem.
