@Kevin_Z the LAN light blinks on and off, all others stay green. No orange. Prior to all this - no problems- just thought time to upgrade from an old AC1100 router. Btw - what is WAN0 vs WAN1? thanks

Apologize if this turns out to be a duplicate thread - didn't see my previous one. Replaced my old, but working Apple Extreme router with the AX1800, now streaming video at times has buffering...
