Theoretically, is it possible to access the internet through a browser without connecting to an ethernet cable or using WIFI?
Yes.There are several other ways to tether internet to your PC.
- Bluetooth Tethering
- Tether using USB cable from UE
- A USB dongle with 2G/3G/LTE connectivity
- Intel is also pushing chipsets with Simcard connectity. So it will be as simple as to put a sim card in your laptop and browse.
I'm sure there are some other alternatives too.The above mentioned are some of the options I can think of now.
