Slowdown speed after switching from Spectrum RAC2V1S router to Asus RT-AC86U router
I just switched my ISP from Frontier FIOS 75/75 to Spectrum Ultra.
I got both Spectrum Modem and WiFi Router (RAC2V1S). The speed I am getting is really fast, download 300Mbps. I originally wanted to use my Asus RT-AC86U router because I am more familiar with their settings.
I basically swapped Spectrum RAC2V1S to RT-AC86U, the speed decreased to almost 80Mbps download. I also tried, Modem -> RAC2V1S -> RT-AC86U but it was worst, about 20Mbps.
Did Spectrum added some proprietary technology between Modem and RAC2V1S so that if I use other router, I won't get 300Mbps-ish speed?
