Depends also on which frequency you are connecting on. 2.4 will never get close to 100.
For example, my Macbook Air and iPhone7 both get 220mbps on my Vivid200 wifi connection - but only when I put them onto the 5GHz network. Sat in the same spot if I then flick them over to the 2.4GHz network, they max out at 70-80mbps - it's just the limitations of the technology!
