Hello everyone I am a new user. I have an Asus N551JM laptop (the 16gb ram version). I recently changed the network card to this one: MPE-AX3000 because the one I had before had 300mbps bandwidth and at home I have gigabit fiber and other devices can reach about 800mbps download and 100mbps upload. But alas, after changing it (including installing the new antennas) and installing the driver, there was no difference (speed test). Is it possible that the Mini PCIe interface has such low bandwidth?
