I have AT&T as my internet provider with 1000 fiber. I haven't made any software or hardware changes in months, lately my wi-fi network disconnects many times during the day. I have checked the at&t modem and it has a connection. I have run speed tests on the BGW210 modem and it is up and running with good speeds, 994 mbps down and 906 mbps up.. My Deco network speed is awful, 8.8 mbps down and 1.3 mbps up or other similar slow speed. I have run the Deco network optimizer multiple times. I live is a single family brick home community for the past 5 years, with no new homes near by. 

I am about ready to chuck the Deco's and just use the BGW210. I need some suggestions.
