To further proof the issue I now tested the same scenario with another wifi usb module in the same network/router setup, this time the driver module was rt2800usb. Same result.
Before using a vpn (pppt) connection my network connection seemed very stable, I had no connection losses and performance was quite good. Again establishing the vpn-ppt-connection with network manager (like above) works basically, I can open a few websites successfully for instance, but after a very short time the connection is completely faulty. This time the connection stayed functional about 30 seconds, then I got packet loss and no more network connections worked anymore. Like before though, network manager showed the vpn connection is still "active" (established) albeit no more packets were transferred. I attached the new error/debug log for this test. ** Attachment added: "syslog_pptp_vpn_debug_rt2800usb" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1763157/+attachment/5126432/+files/syslog_pptp_vpn_debug_rt2800usb -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1763157 Title: Network manager PPTP VPN connection very unstable, connection breaks (lost packets) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1763157/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
