Why is slow wifi attributed to the mi box? It's the mi box fault you got old tech slow router? I bet when my mi box arrives tomorrow I will have fast speeds coupled with my R7800 router and no problems playing 4K HDR Atmos movies.

 after the Oreo wireless AC is capped at 60 Mbps on my end. Its not the router's fault because i'm getting good speeds with my nexus player and Nvidia shield. 
if you check the first image all of them are getting good link on my router.
I already tried another wireless AC router and mibox is still capped at 60mbps. 
Before the update I can watch 4k HEVC Remux movies with 40 to 70 Gb in sizes. Now after the update everything is broken.
So even if you have the fast router it will just stay capped at 60 Mbps and you won't be able to stream those 4k HDR atmos movies.
