I'm using Step 7 V5.5 SP3. My operating system is 64bit Windows 7 SP1.

Yesterday morning I could normally change interfaces in PG/PC settings and I could connect to PLC normally. When I tried connection again yesterday afternoon all but Bluetooth network choices have disappeared (picture attached). Only thing I can think of doing in between was to install Teamviewer VPN driver. Could that mess PG/PC settings up?

Btw. I have hadproblems with PG/PC interfacesettings before. After that all has been rock solid until yesterday. Obviously that solution does not help with this problem.

Any help with restoring connection functionality would be appreciated.

The Siemens support was very helpful with this problem. Big thanks to them!
