Day 2, initial setup of Eero (router + 2 beacons) yesterday around noon. 

Speeds yesterday from the location in the house where i am online most of the time (about 8 feet from one of the beacons) were 70's and 80's, today they are 30's and 40's.  

Any thoughts on this? Others seen this problem? Wondering if these routers might get "cobwebs" and require reboots to clear them out over time? Did not see this w/Orbi setup I came from. Orbi was not stable, but speeds were consistent (and higher overall). 

Appreciate any suggestions. FW is updated on all units, beacon placement was completed successfully w/thumbs up from mobile app, no changes in devices attached to network. Early AM vs. mid-day testing yesterday so congestion in general should be lower on ISP.
