I have an issue when trying to use wifi hotspot or USB tethering. I am able to connect to the G3 without any issues, but when I connect there is no Internet access on the device I connect with (the G3 still has Internet access when tethered). I have tested this with my laptop and also a different phone and neither device can access the Internet when tethered to the G3. I have also tested the sim card in another device, and confirmed that the sim is not the cause of the problem - the G3 is definitely the cause.
Does anyone have any idea why this might be happening, or how to fix it? I'd prefer not to root the phone.
LG G3 D855, 32 GB version.
I am not rooted and I'm using the stock ROM.
