Almost every afternoon, Internet speed crashes around the same time.

Hi Becky, typically I am using a laptop wirelessly, an IP phone is wired (but idle) and a few items are connected but inactive (Nest thermostat, sprinkler controller, Roku & Dish systems on TV's not turned on, locally connected printer).  No streaming, no gaming, etc.  Just normal Internet browsing (email, etc).

I will try the speed test on hard line and report.  Thank you.
