I think he wants the wifi dingle to let the PC use the phone's hotspot
feature ...

just about every pc these days has wifi already built in. it's not
exactly a new technology nor is it esoteric.

nevertheless, in the event the computer is old and does not, the best
solution would be a dual-wan router which will automatically switch to
a tethered phone or a 3g/4g data stick whenever the main link fails (or
even another broadband provider). alternately, just connect the phone
when needed.

the next best solution would be a travel router to bridge the phone's
wifi to ethernet. many travel routers directly support tethered phones
and 3g/4g dongles in addition to wifi, making it even easier, and a few
even have vpn built in.

another option is an ethernet adapter for the phone, however, not all
phones may support it. one such adapter is this (there are others):
