Re: No network connection on guest mikeasmith Nov 22, 2013 5:38 PM ( in response to yby ) Just upgraded to windows 8.1 (64bit) from windows 8 (64bit) and also experienced the complete loss of network on all virtual machines (5 of them). Apr 13, 2016 · But alas, in the Ubuntu Bash shell I get no connectivity. It appears the problem is that the Ubuntu subsystem doesn't deal properly with IPv6 IP Addresses that are listed by default in the network resolution file. The IPv6 addresses are first in the list and apparently that doesn't work. It is sometimes possible for the connection routing to hit a dead end, which then results as a failed connection. Run a route trace from your server to see at which network node the connection gets lost. Ubuntu servers have a networking tool called mtr for this purpose, start it with the following command. mtr 8.8.8.8 Did a fresh install and everything was fine. After a reboot I find there is no network connection at all. I rebooted again and it was there, then I rebooted after that and it wouldn’t connect again. Bringing the interface down and up seems to work, but I shouldn’t have to manually do this. Something is wrong. It didn’t do this on the prior version.

Oct 24, 2019 · Knowing how to configure and display network settings is essential when installing an Ubuntu server or desktop. It is also useful for troubleshooting problems with your Internet connection. The basic network configuration includes setting the IP address, the subnet mask for internal communication, and a gateway for connecting to external networks.
