Everything was perfect until a week ago when an erroneous installation of Google Earth destroyed speed internet. Uninstalling the Google Earth has not solved his problem.

Solution
ifconfig does not show your 3G adapter (it shows wlan0 adapter only), which seems to be connected to "Orange-d534".
You **somehow** disabled your 3G adapter...
There is no way an app (Google Earth) will "destroy the Internet", this is not Kim Kardashian ;)

- What is not working? From your log, one can see you have a WiFi adapter, and have disabled Wired Ethernet, and disabled "Huawei CDC NCM device". How you got these two devices disabled?
- What does "ifconfig" say?
- How do you manage your network connectivity (GUI, command line)?
