My internet connection used to be a direct LAN connection to my provider. Back then, everything would load fine on both Windows and Ubuntu (dual boot). However, a while ago they started needing me to dial using a username and password (over a PPPoE connection). But since then, I haven't been able to browse certain websites on Ubuntu, even though there have been no such issues on Windows. Some example websites are - Ovi's sign in page (although share.ovi.com loads fine, and nokia.com loads fine), Live Mail (works on Chrome(ium) and Opera but not on Firefox (both 3.6 and 4)) and other random websites.
Some of the websites that don't load show timeout messages on Chrome and for some websites, the browser will keep trying to load without an end (I've left it like that even for hours but not noticed anything different happen).
I have tried changing the DNS servers to the ones suggested in the comment. I have even tried booting from a Fedora LiveCD and then changing the DNS to those (and even to the ones of OpenDNS), but the exact same thing happens.
Here's output of ipconfig on Windows:
If it's any help, Opera error messages seem to be a little more informative and they have the following errors in turns:
- Secure connection: fatal error (552)
- Secure connection: fatal error (40)
Followed by: Opera was not able to connect to the server. The server may be using the unsupported SSL 2 protocol, which is not considered safe enough for secure communication. The site owner should upgrade to TLS 1.0 or newer.
Does anyone know why this is happening and how it can be fixed?
Update: Just saw here http://ubuntuforums.org/showthread.php?t=1571086&highlight=pppoe that someone else was having similar problem and solved it by putting a NetworkManager.conf file in /etc/NetworkManager. What needs to be in that file?
