i used that command but I think there is more to do

When I do the command:
sudo route del default gw 192.168.0.2
I see this:
SIOCDELRT: No such process
And I do dig raspberry.org I see this error:
bash: dig: command not found

I think that something is wrong in the hardware

the router is working perfectly this is the netstat -nr output pi@raspberrypi:~ $ netstat -nr Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 192.168.1.2 0.0.0.0 UG 0 0 0 eth0 0.0.0.0 192.168.1.2 0.0.0.0 UG 0 0 0 eth0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 ...

Sorry for adding confusion So insetting up your own eth0 use sudo ifcinfig 192.168.0.101 netmask 255.255.255.0 up Default gateway sudo route add default gw 192.168.0.1 The point was to find out which step fails in order to fix the setup or hardware. I just dumped the text from my setup and I am usi...

I configured all with your numbers but now on the network logo I view: eth0 Link is up configuring eth0 Expired 192.168.1.101/24 I do this command:suds if config 192.168.0.101 netmask 255.255.255.0 up And the results: SIOCSIFNETMASK: No suck device 192.168.0.101: ERROR while getting interface flags:...

The numbers must match your own?

i followed that guide:https://defgw.wordpress.com/2016/01/14/ping-8-8-8-8-ping-icmp-open-socket-operation-not-permitted/ and now the result is changed: pi@raspberrypi:~$ ping 8.8.8.8 PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data from 192.168.1.101 icmp_seq=1 Destination Host Unreachble from 192.168.1....

This is the result:
pi@raspberrypi:~$ ping 8.8.8.8
ping: icon open socket: Operation not permitted
pi@raspberrypi~$ ping google.com

I used NOOBS to install Raspian and if I go on the network icon shows: eth0 Configured 192.168.1.101/24 would the ip address of the raspberry pi although I do not know what it's like that 24.
If I go on the browser I give me error and check the internet.
Help?
