No receipt needed as it was purchased against your costco account...they
can look it up. I did have the original boxes but that's not technically
necessary. Just returned, purchased first half of 2020.
BTW, successfully returned to Costco with no issue and purchased the new
Nest Wifi Pro, which is working very well (for now). Basically cost me
net $50 to upgrade to the new 4 piece system.
At this point I'm giving up. I'm returning these to Costco (thankfully I
bought them there) and getting the new nest wifi pro from Costco. If
that sucks, I can just return them there too. Problem solved.
Nothing really new. I have worked through google "support" who
eventually sent me a new hub. That was when I was annoyed because it was
dropping every one or two weeks now it's at least twice PER DAY.
