I recently up my Laptop as a dual-boot for Windows 10 / Linux Mint.

For some reason, despite WiFi connecting to my router OK, no web sites will resolve in the browser. No response from the Mint forum at all.

@timrowe do me a favor. Open a terminal and run 'nslookup google.com' and respond with the output?
@Rtzq0 Have tried ping but no response. Currently able to connect to WiFi via tethering Android phone.
@timrowe That looks suspiciously unlike the output of nslookup google.com ;-)
@Rtzq0 no response to that command.
@timrowe just tested this on a mint VM. Even if you have no network connection that command produces an output. Please keep in mind that I'm trying to help a random stranger on the internet for free, please either supply screenshots or copy-pasted terminal output. Otherwise I'm not going to be able to justify spending time trying to help.
