I have a lot of network problems since I made the upgrade to the 11.10
In our company, We have 3 computers upgraded to the 11.10. Every one of this have network problems. The other computers are under Ubutun 11.04 ands works fine.
The network problem are not constants, sometimes after a reboot it's working. But if there are a problem I stay since a reboot. For example we have :
- Connection troubles : streaming music does not work more than 30s, a lot of AJAX request does not work.
- Error on requesting a webpage, the browser (firefox, chromium) doesn't find the hosts
- Error often on requesting a webpage for a /etc/hosts host
- Error on ssh or scp, display the message : no root to host
- Error on svn.
We already tried :
- Desactivate IP v6
- Install Wicd instead of "Network Manager"
- Replace the /etc/resolv.conf by static data
- etc.
Is somebody have an idea ?
Thanks a lot !
See you, Thomas.
