Comment 4 for bug 1763157

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.
