My router has begun displaying a solid orange light (no internet) sometimes, about once a day and so far twice today.  I fiddle with unplugging the router and the modem and eventually it goes back to blue.  But this isn't acceptable because we work at home and it kicks us off of Zoom calls, etc. (Not sure whether coincidental but earlier this month our cable modem would occasionally disconnect us and I would fiddle with that and it would work again.) Firmware is up to date. Any idea about how to eliminate the problem?
