I have a Nighthawk R7000 router and it's worked great up until a few weeks ago when I plugged in 2 Amazon Echos. I don't think that's the problem though. My 5G WiFi cuts out from time to time and when I unplug the router and plug it back in everything is fine or if I wait a few minutes it will work itself out and come back on. It's only the 5G that cuts out. Could I have too many things plugged into it or maybe too many things plugged into the router all together? I have about 17 devices plugged in at one time, including a WiFi extender. Any help would be appreciated.
