Nathan recently created a dual boot PC using Windows and Majaro Linux. But now his bandwidth speed on that PC is really slow compared to his other devices. Leo says that if the slowdown is evident on both Linux and Windows, then that points to a potential hardware issue. Leo recommends to boot into Windows and go into the Device Manager to make sure the PC is using the proper drivers. They should be by Intel. He can also do a Linux LSHW (list hardware) command, or LSPCI command which will show what ethernet and Internet commands are being used. Booting into Windows and using the Device Manager would be easier. Make sure all the settings are proper. Then try removing the device driver and reboot. Windows will then reinstall the network interface driver.
