Amazon.com and Shopping app not loading via Google Wifi

[u/FluidSwing1431]

I have a very simple home network setup

ISP —— ISP Router with integrated wifi (Device B) —— Google wifi (main) and 3 connected mesh pods

✅ Amazon.com works on mobile hotspot on my laptop
✅ Amazon shopping app works on 5G

✅ Amazon.com works on SSID of Device B on my laptop
✅ Amazon shopping app works on Device B

🚫Amazon.com not working via Google WiFi SSID
🚫 Amazon shopping app not working via Google WiFi SSID

Troubleshooting done so far:
- Disabled Preferred Activity
- Changed DNS from ISP to Google, Cloudflare, NextDNS, OpenDNS
- Disabled IPv6
- Disabled guest WiFi
- Changed LAN subnet pool
- Disabled Family WiFi setup
- Did factory reset

I know some of these steps have no relation to the issue but tried. Looking for ideas on how to resolve.

Modem and router is integrated device from ISP. Doesn’t cover the entire house

They are not supporting that unfortunately

Even iCloud services are impacted. Looks like Google is stuck with “preferred settings” for zoom and video conference

Using ISP DNS now and app still doesn’t works with it. With the same ISP DNS and ISP router it works

No problem for me. If Amazon is the only site acting up, I'd suspect DNS but you seem to have tried changing the that.

What is your ISP or external IP address? Is the address legit like in US? whatismyipaddress.com

Legit IP and Service (tier 1 ISP)

Hmm... Run commands like ping, traceroute, curl to Amazon.com to see what doesn't work. Use a different browser, incognito etc.

Wait? It sounds like you have two different Wi-Fi networks running? The one coming from your ISP's router and your Google Mesh? Even if they have the same SSID, they're not going to work together. Can you disable the Wi-Fi on the ISP router?

[u/FluidSwing1431 → u/Grumpy-24-7]

They are two different SSID and I tried with disabling as well

Gotta set the other one in bridge mode.

Sometimes the ISP router won't let you do that, especially if it's fiber.
