I set up my old hhg2500 router as a repeater for 5 ghz, turning dhcp off and connecting it from one lan port to another.
It made not only the repeaters wifi but the wifi from the main router give off errors such as the "this site cannot provide a secure connection" error on most sites, it also made the internet on both slow and almost unusable even though speed test said 40 down 8 up.
