double NAT

[saithan]

i am using google WiFi router as mesh in my home with 6 router , but the moment i got my fiber optic   internet the speed suppose to be 200MBS , but i have noticed drop in the speed to 50% , when i tried to search for the reason i conclude that  Double NAT is the reason , so i stop using the google WiFi as mesh and i started using them as router ,things got OK internet speed 100% as it should be , and the moment i go back and use them as mesh the speed of internet goes back to 50% gain

i communicate with ISP to see if they can disable the NAT in their modem and use it as bridge but this is not possible since the are the provider

i need help

Hi saithan,

Your two options are essentially:

1. Remove your ISP-provided router, replacing it with your Google Wifi router (if possible)
2. If that's not possible, you can enable bridge mode on your Google Nest Wifi router or primary Wifi point.

Note that option 2 is only an option if you’re using a single Nest Wifi router or Google Wifi point. If you’re creating a mesh network with multiple Wifi devices, your Nest Wifi router or primary Wifi point cannot be in bridge mode. I've linked a help centre article below that explains in more detail.

3. I will get rid of my google wifi....

I have the same issue. By multiple contacts with customer care and searching in internet about it, what can be done is that setup your ISP router in bridge mode and whatever credentials are required for login to ISP can be done in nest wan settings. That’s way ISP router will be just a modem and all basic protection like firewall and dns will be done on nest router
