I have a MacBook Pro (running OS X and Windows) with a broken Wi-Fi card. I plan to get the Wi-Fi card fixed soon, however I want to back a few things up on the Internet before I hand off my Mac to the Genius Bar.
The last time I had this issue, I had an Android phone and was fairly easily able to download an app (FoxFi, if I remember correctly) and share my Wi-Fi connection with my laptop via a USB cable.
From reading answers to similar questions, it seems that according to Apple a Wi-Fi connection cannot be shared. I understand why a Wi-Fi connection might not be possible if you're using the antenna to broadcast a Wi-Fi hotspot, but why would you not be able to share a Wi-Fi connection over USB? It seems like it must be technically possible for an iPhone and not something that would be restricted due to carrier concerns about cellular tethering.
I basically want to use my phone as a Wi-Fi USB dongle and don't want to buy a USB dongle because I'm planning to fix my Wi-Fi soon anyway. Also, I don't have easy access to Ethernet at the moment.
Note: I do not want to use cellular data, only Wi-Fi. I would prefer a solution that doesn't involve jail breaking my iPhone. I do not wish to enable hotspot if I have to pay for it (I am on Verizon, which does not allow free cellular tethering).
