Pixel 9 WiFi- No internet

Got a pixel 9. It seems to have the same WiFi connected - no Internet problem that I had on 6a ,7 & 7 Pro

Other phones (iPhone & Galaxy) at home can connect fine & have switched ISP since the 6a & 7 had same problem.

It is pretty frustrating. I have reset router, switched compatibility mode on and off (on router) Turned off the adaptive WiFi (on Pixel) Tried forgetting network and reconnecting Reboot phone Turned off private MAC address.

Does anyone else have this problem & how did you fix ? I feel it is a Pixel issue. But if anything else I can try please let me know
