Hello, my current motherboard is veriton E430, in driver informations I found that it uses realtek as LAN provider. More specifically Realtek PCie Gbe Family Controller, which I believe has only standard 100 mbit throughput. I am paying for 300 mbit internet, so I am thinking about installing some 1 gbit realtek controller, but I am not sure if it is even possible for my motherboard. Or does 1 Gbit connection work already on all motherboards?
