Since yesterday I have a problem with my wired internet connection only on Ubuntu, Win7 works fine (dual boot), Thunderbird hangs at connected to pop3
and receives no e-mails and various websites hang at TLS handshake.: duckduckgo, ustart.org though google is there in a second.
I have already tried
- renaming cert8.db
sudo nano /etc/gai.conf
locate #precedence ::ffff:0:0/96 100
and remove the #.- reboot
- Disconnect from Internet with
sudo tee /proc/sys/net/ipv6/conf/all/disable_ipv6 <<<"1"
Connect to the Internet again
All without success
I do not know commands by heart but mostly try some sudo commands I find on this forum or online, as I am not an ubuntu adept. I hope someone can help, I am now on Windows7 :(
