I'm having the same problem with Ubuntu 11.04. My PPTP can stay up for weeks in Windows 7 and OSX, but in Ubuntu there are frequent disconnects (usually within 5 to 30 minutes). Here is my /var/log/syslog relating to a disconnection:

We have a lot of bad checksums on your connection." -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/225156 Title: pptp disconect when get some info To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pptp-linux/+bug/225156/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
