There's no way to get internet to the router that way, If you mean connect the PC to the router using Ethernet (RJ-45) that's different.
and then share mobile hotspot
1. The hotspot is a router. 2. You don't "share" the hotspot
with anything, things
connect to the hotspot.
from my phone to that router. That doesnt work? I am no expert what it comes to these things. Thats why I ask before buying anything new. Afaik that DWA-171 dongle does just that same thing except it is just a stupid dongle without anykind of utility programme where I could choose with frequency to use.
A dongle is just a WiFi adapter for a computer that doesn't have WiFi, but has a USB connector. (Or adding 802.11 ac to an old computer that has only bg.)
I do have fairly fast connection on my mobile and to my knowledge (I might be very wrong here) 5ghz could increase the speed
No, frequency has nothing to do with speed. Protocol (b, g, n, ac, ax) controls speed. (That and the signal strength and quality.) Going to 5GHz basically gives you more channels (useful in a crowded building, especially if it's full of 2.4GHz signals from other families) but shorter range and less penetration.
Also I still wonder why I cannot change frequency on my mobile at all even tho it supports both frequency's
What you can do depends on the software provided, and that depends on the manufacturer (Samsung may only allow band changing in flagship phones, for example) and the carrier (some may actually have the hotspot disabled for certain plans).
