Downloads won’t be rough at 500mbps

You could theoretically download a 25gb 4k bluray movie in 7 minutes , then it would take 90 minutes to watch it

Unlikely going to a gig would be any faster as you’d need a server capable of more

I am a tech guy who lives alone and I pay for 35 for 200. Gig is available but it just wouldn’t make any difference beyond occasionally downloading a brand new 100gb video game. But I don’t do that often so an extra ten minutes is rather meaningless

It depends on the device

Usually green means 1000mbps and orange means slower. But that’s not a guarantee and won’t be true on 100mb devices, where it’s likely to be 100 and 10

If you don’t have line of sight forget about it. Trying to run a ptp in a city with NLOS is going to be garbage
