can't reach ipv4 connections

Swaipy · 2023-06-02 21:12:50

i cant connect to any ipv4 server, if i try to ping google.com i cant but it only shows an ipv6, and when i try to ping github.com it doesnt send the ping.
its not an isp problem because from my phone i can enter those websites.

Please post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

Do other computers on your network work with IPv4?
Do other operating system on your computer work with IPv4?
Do you control 192.168.0.1 ? Does it have a shell interface or does it have a GUI with internet test capability? Can it see public IPv4 stuff?
Have you tried rebooting 192.168.0.1?
Has it ever worked? Any chance your ISP is having issues?
