Download speed drops randomly to 90-95mbps almost everyday, can happen twice a day and some times it's good for two days before it drops. Normally I get 490-500mbps download. This started happening on the previous update, not sure of the version number I had before. Newest firmware 1.5.0 didn't fix it. 
 

A quick fix is to take the power in and out or do a restart through the app. This works every time. 
 

Any tips or is it a known bug in the firmware?
