2.4G wifi advertising 600Mbps on mr60

[Tj2041]

I have the latest firmware on both my router and satellite but I cant seem to get the advertised 600 Mbps on my wifi while connected to the 2.4g. my isp plan is 650/100 and I can get that while connected to the router and am sitting in the same room but other than that I get around 200-400/100 around on the first floor (router in basement). on the second floor where the satellite is when connected to that I get from 50-110 Mbps download and 100 up and that's on the 5g network of the satellite, I've tried moving it around and even ethernet backhaul but ethernet backhaul for some reason slows the speeds down more

You won't hit 600mbps over 2.4ghz. 2.4ghz is a slow network as well as its only "link speed"

link speed isn't the same as actual throughput speed because of network overhead/interference/obstructions. 

Plus a lot if dependant on the device you're using to connect with as well.
