Ubuntu server can't reach default gateway/internet

bake_betty

Update: If i change the ip to 10.0.0.11 everything starts to work. 10.0.1.1 is still in the same range in a /22 subnet so it should still work? I have a very peculiar problem with Ubuntu 14.04. I moved apartments and connected it to a new router with a new ip-range. I changed my laptops ip-address to the old range temporarily, ssh'd to the server and changed its static ip to match the new range: auto p1p1 iface p1p1 inet static address 10.0.1.1...

Great question — answering as the UphillTech team:

Instead of broadcast ping you should use arping to check router IP address arping 10.0.0.1 I think that the mask on the router is wrong (like 255.255.255.252 instead of 255.255.252.0)
