SIOCADDRT: No such process. the trick is simple , first add a route to default gateway itself and then set the default gateway , like this : route add e.f.g.h/32 dev eth0 route add default gw e.f.g.h. remember you may need to change eth0 to your device name , it may be eth1 or wlan0 or anything. How to make these route changes persistent ?
Since a few days, my pc running 16.04 cannot access the Internet anymore. I have tried disabling Ipv6, swapping the USB network adapter and changing the power management behavior, but none worked. All other devices connected to the WiFi have Internet access, even the Windows 10 installation on the same pc. Some info: USB network adapter: tl ネットワークインターフェースを設定した際のコマンドなど - 午 … 新しいNIC（ネットワークカード）を導入したのでそれに移行した際のメモ。 装着したNICが認識されている事を確認 ifconfig ifconfig -aでアクティブでないインターフェースも表示。 dmesg dmesg（display message）でハードウェアのメッセージが表示できる。以下例。
