@alekhkhanna , I'm not commenting about why your speeds are less.
I'm only conveying to
@yougotmehere, that if he has an internet connection that can provide a
500mbps speed on LAN, he will be able to achieve his desired wifi speeds of >= 400 mbps* I've only a 100 mbps connection. So I can test max wifi speeds locally only. So I shared my device /
router / server details, and a screenshot of the result. From a standpoint of measuring wifi speeds, how is it different from a speedtest server?
This is a video found on youtube of someone testing the same
archer c6 router on a speedtest server.
Youtube - speedtest. (I've not gone into his wifi adapter specs.) But you can clearly see his wifi router speeds.
