I am editing this post as I included a lot of un necessary information. Lets just put it like this: I have talked to a lot of different people, and techincal support (That are more familiar with router and networking than me): They all refer to the problems I am facing as hardware problems. I am not going to go over what the different things are, and why as that is not the topic. As I have thought of all the different things you mentioned, but keeping that discussion going is unnecessary (and I dont wanna waste your time). But my conclusion is: My router has a hardware problem, and we are going to buy a new one (I don't wanna waste unnecessary time for you. Sorry for the inconvenience)  

I am from sweden, so amazon and ebay are not valid choices for me. But it all lies in at usually the same price. So thats fine. I have a budget of around 150$, and we have wireless connection, 4G
