Recently I upgraded my internet connection to 100mbps and my router’s max speed supports up to 750mbps and it’s a dual-band router. So, when I am connected to 2.4Ghz I get a speed of 40mbps and at 5Ghz I get the speed of 95mbps. Do I need to buy a new router because the only thing I want is my internet plan speed in 2.4Ghz band.
