Connection = cable box to TP-Link Archer C8 AC1750 to Win 10 desktop. Wireless worked fine this morning via iPad, then came back an hour later and there is now no internet thru the Archer and no lights, except two momentarily when powered on. What works: 1) cable box to computer gets internet on PC; 2) iPad shows connection to router, i.e., router name checked in Settings, but then can't load any sites; and 3) When router reconnected between cable box/PC and reset pushed, the right light (opposite facing arrows flashes continuously). Wiring seems fine. Ideas? Do these things just die? Thanks,
