My father has a RTC connexion (serial modem 56K) and Firefox 3b5 on Ubuntu 8.04, whereas gnome-ppp handles the connexion, and Firefox always starts in offline mode. I've desactivated network-manager on startup (from preferences menu) but it didn't fix the problem Uninstalling network-manager from synaptic solved the problem.
Then for me the solution was : uninstall network-manager Make use of gnome-ppp to handle the internet connexion Note that i've also tried to connect through System>Administration>Network The connexion was ok but Firefox couldn't make use of it to access to internet -- [MASTER] Ubuntu's new "Offline Mode" feature cannot properly detect when there is a valid network available for use in many circumstances https://bugs.launchpad.net/bugs/191889 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
