Error Network is unreachable for WIFI

ax flag
Vaterno

For some unknown reason, WIFI stopped working (Internet via cable - works properly), when pinging - it gives the following ping error: connect: Network is unreachable. I'm new to Ubuntu, can anyone tell me how to fix the problem with WIFI? Thanks!

All I see is `eno1` which suggests an ethernet device. The 169.254 suggests that your DHCP on your network is busted which handles automatic IP assignment. Reboot your router and your computer and try again, both Ethernet and Wifi.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
