# ok, no more internet sites responding and package loss at 100% vpn still seems to be connected but is completely broken. # Then 21:13h now after making test connection to ca. and making some traffic, after a short time the bug situation occurs. # debug mode has been set now for better logging IPv6: ADDRCONF( NETDEV_ CHANGE) : wlx000d81af00fb: link becomes ready IPv6: ADDRCONF( NETDEV_ UP): enp3s0: link is not ready IPv6: ADDRCONF( NETDEV_ UP): wlx000d81af00fb: link is not ready

HIDEME VPN AN UNEXPECTED ERROR OCCURED DOWNLOAD
Making a lot of traffic, parallel download etc. (Module output: insmod /lib/modules/ 4.13.0- 38-generic/ kernel/ drivers/ staging/ rtl8712/ r8712u.
I start with resetting wlan module r8712u first, letting network manager establish a new connection to my wireless lan at 20:50-20:51h. # here I try to demonstrate a typical situation, first stable later the error
The vpn sites are working good with other clients, also the wlan (WPA2) and wlan router itself at my home are working fine, several other client system (Windows, Mobile, another Linux) are working without any issue, thus it is definitely this specific network manager wlan/pptp-vpn client with the r8712u module causing the trouble. Network manager does not show a no-more-working connection visually (regarding the symbols all looks good) but it is quickly noticeable that no more internet sites are reacting as soon as the bug situation occurs (which is very often, normally only after a few seconds!). Example pptp vpn is ca. but I tested other connections as well with the same result. Wlan connection seems quite stable basically but as soon as I start using vpn it quickly is broken after a very short time. The wlan module is r8712u (Realtek Semiconductor Corp. The PPTP-VPN connection over WiFi of my Ubuntu Xenial installation is extremely unstable, repeated loss of connection (100% packet loss), easily reproducible using network manager.
