Continuing the discussion from Tethering WiFi to laptop USB:
Searching the Q&A showed me a mention of Reverse Tethering, BUT: seems the question and answer is a bit off. What I would really like to do is connect my phone to my laptop with a USB cable and use the LAPTOP connection to the internet for data. Could / should be faster than via WiFi, since my laptop is directly Ethernet cabled to the internet adapter.
This should also solve an issue for my son at college. His mobile wireless (cell) connection is not good in his dorm, and neither is the WiFi connection for his phone. If he could connect his phone to his laptop with a USB cable and have the phone get data that way - Great!
Can this happen? With my Moto G5+ connected to my internet-connected laptop the option (under Android Settings - Wireless & networks - Tethering & portable hotspot - USB tethering) will de-gray when a cable is connected, but will NOT stay turned on.
