At the same time I subscibed to the NBN I purchased a new computer.  What happens is that when my computer goes to sleep the ethernet connection is effected and although it shows a connection icon in the bottom RH of my screen there is effectively no internet.  The internet will come back on and works perfectly if i reset the modem/router.  Restarting my computer or unplugging the ethernet cable does not fix my problem.    I have tried another computer using the ethernet connection and it works fine.  Also the wifi works fine at all times (even when there is no ethernet internet).   I rang TPG and they went through their checks and advised that the problem was my end.  I have reloaded windows, looked for updated drivers for my ethernet card and the problem persists.   Today, I plugged in my old modem/router to the ethernet connection from the Archer VR 1600v modem/router and then to my computer.  Using the old modem/router between my computer and the Archer modem/router appears to have fixed the problem.   The motherborard that I am using is a MSI B350M and it uses an onbord Realtex 8111H Gigabit LAN controller.   I believe that I have an interfact conflict between the hardware/software and am not sure where to go from here.  Do you have any advice regarding this matter please?  ...
