I am using a private hotspot to connect a Raspberry Py to internet. I've setup the password and the ssid in the /etc/network/interfaces file. With this configuration I'm able to connect to the wifi but I can't connect to internet.
pi@tenzo /etc $ ping google.com
PING google.com (173.194.40.2) 56(84) bytes of data.
From tenzo.local (192.168.1.115) icmp_seq=1 Destination Host Unreachable
I've asked around and they said it's a gateway issue. Running traceroute from a laptop connected to the same network I get:
userk@dopamine:~$ traceroute google.com
traceroute to google.com (216.58.212.110), 30 hops max, 60 byte packets

Do you have any advice?
EDIT 1 I've added to the interfaces the gateway, address and netmask. SEE EDIT 2
Now, when I ping google.com I get the same error as before...
This is the output of route -n
pi@tenzo ~ $ route -n

EDIT 2 This is my interfaces file:

iface eth0 inet static

This is the output of traceroute

A gateway would need to be configured in your interfaces file; e.g., something like
iface wlan0 inet static
address 192.168.x.y
gateway 192.168.x.z
netmask 255.255.255.0
would work (where x is your network number, y the address for your host, and z the address for your gateway). Obviously you need to retain your encryption settings, too.
If you're using dhcp on that interface, then something is wrong with your dhcp server.
EDIT: you should also make sure no other network interface has a gateway setting, or if it does, that the gateway setting on that interface is correct. A "gateway" or "default gateway" is a machine which offers a connection to the Internet. It is a valid configuration to have a network interface without a gateway line if no such host exists on that network connection.
In your case, assuming there is no internet router on the network that eth0 is linked to, you should ensure that the iface eth0 stanza looks like this:
iface eth0 inet static
address 192.168.1.115
netmask 255.255.255.0
i.e., what you already have, but without the gateway 192.168.1.1 line. (the indentation at the start of the line is optional, but does make the file easier to read).
