Title: ! Cannot connect to internet in Ubuntu 17.04 (DNS Lookup fails) Status in network-manager package in Ubuntu: Confirmed Bug description: Hello, I think this is a bug in the WIFI-driver or kernel. Ubuntu is connected to the WIFI (router) box, but it cannot find DNS server to get to the internet. I have periodically *serious* problems with WIFI in Ubuntu 17.04. The network icon shows "connected" to the router and internet, but browsers and other attempts to get data report DNS error / or not connected. This happens in all flavours of Ubuntu 17.04 (Ubuntu, Ubuntu GNOME etc.). Same laptop with Ubuntu 16.10 works flawlessly. The connection works fine after I reboot (power off/on) the router box. Then the bug may return (or may not return) after I turn on my laptop next time. This laptop is Toshiba Stellite P50 C. The laptop has Intel Corporation Wireless 3165 (rev 81). $ lspci -nnk | grep -iA2 net; uname -r; ls /lib/firmware/ | grep 'iwlwifi-7265d' 0d:00.0 Network controller [0280]: Intel Corporation Wireless 3165 [8086:3165] (rev 81) Subsystem: Intel Corporation Dual Band Wireless AC 3165 [8086:4010] Kernel driver in use: iwlwifi -- 0e:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.
