Bests & Worsts Reviews from Amazon

I was excited to get this new router and anticipated an upgrade from my 6 year old Nighthawk router. The installation was easy. I don't care for the app very much as it seems glitchy. The device is a good size as well. The issue lays in the speed and reach of the device. They have their disclaimer to state speeds may vary which I get. I have a 1200sqft home (this states it is good for 2000sqft) and attained speeds of around 700mbps where the modem and router are. Two rooms over I am reaching speeds of around 25mbps. This is 28 TIMES SLOWER. Unbelievable and unacceptable. I am hoping they roll out an update to correct whatever deficiency exists otherwise I'll be sending it back. My 6 year old router attained speeds of around 125mbps in that same room. Another issue I have is for such an established company to have no customization in their app is astounding. Me as the customer should be able to choose what band I wish to use and also choose which node should receive priority. All in all I am not sure why we paid $230 when a similar device of around $80 could have done the same thing. I checked the forums as well for advice on how to correct the issue and the answers left by the manufacturer are they have no intention of implementing any additional suggestions. Even though the comments were overwhelming in support of additional features to optimize your wifi settings.
