I was surfing the Internet, and suddenly (I didn't do anything, did change any settings, only were using browser) - Interned disappeared. I thought something with the router, I rebooted it, then my phone and the other Ubuntu-PC successfully reconnected, but my notebook Can not access any server. Looks like there is no Internet.
But if I start
expressvpn connect it can successful access its servers and establish the connection, and than my browser can show web pages.
What happened, how to reset this behavior? I can not access Internet with VPN being connected.
I tried this
How do I reset my Network settings to default? - doesn't work, can see any wifi networks.
Also I flushed
/etc/network/interfaces - doesn't help.
I tried reinstall ExpressVPN too - didn't help.
How to get back the default behavior. I don't want reinstall Ubuntu, it's not Windows, when you do it every time something doesn't work, right?
