Ok, i solved also the network problem. Now i can surf wherever and my pop3 connection with thunderbird are working now. Is a problem caming from the kernel, where was changed the parameter to activate the TCP WINDOW SCALING.
The TCP WINDOW SCALING is active by default in the kernel, but there are a lot of networking systems that doesn't understand windows scaling and they cannot comunicate. For the RFC the tcp window scaling can be used only after a SYN-ACK connection, so the for SYN packet is exchanged and after when TCP Windows scaling begin to work the network communication goes in timeout. Here is why i can see how many messages i have to download in thunderbird but i cannot get it. Here is the solution : as root user or with sudo echo "0" > /proc/sys/net/ipv4/tcp_window_scaling Just to see if solve your problem, if yes, you can make this change permanent by adding this line to the file /etc/sysctl.conf : net.ipv4.tcp_default_win_scale = 0 Now you can surf anywhere you also and all the network application come back to work. Yes, update-manager also.... finally !!! :-) It's time to solve the sound problem now... -- Upgrade to Feisty Fawn : Desktop, Network and Sound problem https://bugs.launchpad.net/bugs/114754 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
