My Ubuntu 20 cannot connect to any sites anymore. My wifi is working fine & the wifi connection icon on the top of my desktop shows that i'm connected, but i'm not! I've checked to make sure I'm not using any proxies. I've also tried disabling firewall. I've also tried the following commands:
unset HTTP_PROXY sudo iptables -F ping 220.127.116.11 ping localhost ping -c 5 google.com sudo lspci sudo systemctl restart NetworkManager sudo dhclient -r && sudo dhclient
None of them worked.
ping 18.104.22.168 returns a streaming results of 64 bytes on every second.
How can I get my internet connection back?
