Not sure anyone of you facing the same issue as my Mi3 does.

Recently I have tried to install Mi3 USB driver and it is completed.

But when I plug in the Mi3 for USB tethering, I having one issue which is it show the firmware version not the latest, and I'm unable to access to the internet at all. When plug in the phone, it shows the firmware not the latest, but when I click update firmware, it showed the Mi3 already the latest (MIUI JXDMYBD14.0 Stable version), but I just don't know why I can't do USN tethering...

Then I tried Wifi tethering, this time it works, I can connect my laptop to the internet, but after a while (5-10 min), the connection will lost, and I have to reconnect back the Wifi hotspot again, this happen always.

Anyone of you facing the issue as above? And anything you have done to fix this kind of problem before? Please let me know, thanks.

p.s # I doing this by placing my Mi3 near my laptop within 30cm distance, and the phone is fully charged, and I tested with my old samsung note before, the line is always stable there. I'm using Maxis, at that area will have 4-5 bar with H+/H sign.
