Hi, I am thinking of buying router. I plan to connect two computers with wires and one table wirelessly. I saw that there is a lot of different ones with different function and large price span. I saw that there is also a lot of information about advantages and disadvantages. Now I am asking if somebody have any advice or experience, what is god to buy and I also have some specific questions that I am not sure about. - Does "classical" routers has over two floor range? - If you connect desktop computer to router, does the IP changes? - Is every desktop pc and tablet compatibility with every router and which one aren't if not? - How does router on general influence on speed of internet? Thanx for answers.
