Hey guys a few months ago I ordered the M7200 and have had no problems with it so far anyway I recently ordered  2 more thinking they they were the same one but I accidently ordered 2 M7000 which I belive is the better model anyway so not sure why I am having problems but anyway I have always tethered my internet from my m7200 to my pc via the usb cable (my pc cant access wifi) so I need wired and cant always be at an Ethernet on my laptop so ive been using sims in MIFI hotposts but Im just wondering is it unable to use the USB cable essential as an Ethernet with the M7000? Or do I need to do an update or something somehow?

I have attached links to an imgur image of the device that works and the one that doesnt if this isnt allowed PLS delete the links/images but not the post I really need hehlp
