I have a strange little problem on my hands here.
All this while, I've been using iPhone tethering via USB, and all was well.
However, today afternoon, my iPhone USB interface in the Network pane keeps stating that my iPhone USB interface is 'Not Connected'.
Enabling and disabling the Personal Hotspot option on my iPhone does not seem to get it back.
Does anyone here have any idea how I would solve this? Thanks a lot!
