I am living in the dorm and there are no WiFi routers provided by the dorm stuff, we have only a wire access point. In order to have Internet access, you need to plug the wire into your computer or you need to buy a router by yourself. Unfortunately, at the time I don't have mobile internet (or it is not enough), but I need to connect my phone to the internet. However, I cannot/don't want to buy my own router. Is it somehow possible to share internet access between my laptop and smartphone, perhaps with a wire?
