Network is unreachable after login
I have a weird problem: I’m using WiFi for my internet connection. It works flawlessly, until I decided to leave the computer for a while. When I come back, I login into it and unable to surf the internet. The WiFi/network icon remains the same (full connection), but when I try to ping a working internet address, I get ping: connect: Network is unreachable Restarting networking.service with systemctl doesn’t work. Disconnecting and then connecting once again to the WiFi hotspot solves the issue. EDIT: sudo lshw -C network output:

Здравствуйте! На днях каким-то мистическим образом сама по себе возникла проблема с WIFI, т.е. через кабель интернет работает корректно, а вот через WIFI — при пинге выдает что Network is unreachable. Так как ubuntu я использую чисто для программирования, то я вообще полную 0 в настроивании этой OC. Очень буду благодарен за помощь! Спасибо!
