Hi,

 

I have a problem during the upload. I have modem MF680 and router MR3420. Modem is detected and they works together, but if I try to upload bigger amount 40MB+ of data then the modem gets unplugged and only restart the router or re-plugged the modem helps.  Does anyone have an idea how to fix this issue?
