So to the OP, if you want to start another useful HowTo, state upfront no consideration nor discussion of the health risk stuff, give a link to this thread for those who are interested in that aspect.
Then once you've learned your different options for "how to", you can decide for yourself which you think are less dangerous.
Very few people use wired connections between the router and their client devices, everyone sets up WiFi sharing for that,
but enough IT savvy to help with that aspect if you want to go that way.
If you just have the one PC, then a USB-based cell modem will suffice.
