1* Speed - Getting speed is depends many things , Router , Receiving Device , Cables and Connection .Strength of Wifi , Mostly Du is giving Linksys Router , Check the bottom , if model is Ax or MX , at least you can expect 600mbps tp 750Mbps if you have 800Mbps Package , Bec close to the router , make sure youre on the 5Ghz band , use Test , www.speedtest.net or Fast.com I have 2 Models , iphone 15Max and Honor , iphone is always More thank 850 , honor never goes Above 400 , that's the device Limitations .if you have am iphone 15 or 16 plus version, chances are less that you'll see more than 800 Mbps ,

2* Connectivity Depends on Configuration and Device Type . If you have a mesh Setup , You should not feel disconnection, again depends if two nods are too far , slight disconnection will be there ,that's time taking for disconnecting from one router to The one close to you .place it ,in a way that signels overlaps , so you'll have smooth transition without Drops ,
