Slow 5 GHz Wi

Recently I've bought a new router that supports 2.4 and 5 GHz wireless networking. The first wireless access point on 2.4 GHz works fine (with 60-65 MB/s download speed), but the one with 5 GHz is almost dead (0,3-0,5 MB/s download, but iMac actually can connect to it). However, it appears that it's not router issue but macOS, because Boot Camp windows 10 on this iMac see 5 GHz network and its speed is 80-95 MB/s! I tried to reset macOS Wi-Fi preferences, but that didn't help. So does anyone know how to fix that?
