It appears that I have to plug the google wifi into the Fritzbox. What is double NAT and how do I set up bridge mode on the Fritzbox?
Should be able too, i have had no issue plugging it into my router (Asus) and just letting the app do it's thing. Once setup then I just used the google SSD. I still have wifi on the router but I will nuke that in a few weeks when I have moved everything over to google wifi.
Have not run into any NAT problems with it yet.
No VLAN tagging makes this quite limited as you're required to use the Fritz or a switch to untag for you.
I would suggest either the Ubiquiti Amplifi or the Netgear Orbi as alternative and superior solutions then you can ditch the Fritz.
