As mentioned in the comments you are able to ping `8.8.8.8` but can't ping `google.com`. The problem resides in your DNS-settings. Some of your four DNS won't resolve addresses correctly. You might try an other DNS-server e.g. by entering 8.8.4.4, 8.8.8.8 or 141.1.1.1 in your Network-Manager in the IPv4-pane.
Prior to this you might check if this works out by trying: `host nature.com 141.1.1.1`. For me the result was something like `195.128.8.101`.
