I have been using Ubuntu 12.04 for a long time. I update Ubuntu once in a month. The last time I updated networking issues started cropping up.
My internet connection disconnects, and after some long amount of time it reconnects.
I tried searching a lot and tried some solutions, but none of them works for me. The things that I tried are:
- Editing
/etc/resolvconf/resolv.conf.d/head
and addingnameservers
(from google and open DNS) - I did this because I found DNS resolution itself fails, so I thought this might help. - Editing
/etc/NetworkManager/NetworkManager.conf
turning off dnsmasq. - Ignoring ipv6 as suggested here.
...but nothing seems to correct it.
I have to disable-enable networking to fix the issue.
