Ok when i first got Rachio over year ago blink up was fast with same router and ISP. I decided to update wifi and blink up failed and called support and physically moved unit and it worked.
So fast forward.
I installed a second router in home (Netgear Super Duper Router) within 10 ft of garage now running 100/100 Fios.
Same issue....I had to move within 5 feet or same room as router.

Ok lmk if you need any info as this is perplexing... Rachio 8 Zone Gen 1
