@Philbert My modem router is the C6300BD-1TLAUS I have been using for over 4 years. It has worked fine at the beginning but recently the speed has dropped below 2mbps I have reset it again and again...

modem wi-fi I am using has very bad network speed, if I replace it with the TP-link wi-fi modem 3 or more it will work and the connection is stronger? Thanks
