The sim is working fine when directly inserted in phone (4G speed is also good)

But when inserted in the router, Quick setup is successful (including "Connection test" ) but "TP-Link Cloud Service" failing with error

"Oops... The Internet connection is not set up successfully.
1. Make sure all cables are properly connected.
2. Click Reconfig and verify that the Internet connection information is correct.
3. Contact our Technical Support if the problem still exists."

Also Im not able to browse internet on phone , it gives error "connected without internet"

But in my Macbook , it works perfectly and speed is also good.

Also my CCTV camera is not able to connect to internet via this router.

Also this TP link router firmware update is failing with error "no internet avaialble"
