First check SDWAN Performance SLA. 
Edit one of existing default performance SLAs and select All SDWAN-Members

Hi @vishwas_28,

Does the issue start after you created SDWAN? What is the firmware version? Can you provide more details about Internet not working properly? 

To test the Internet speed, you can use iperf: https://community.fortinet.com/t5/FortiGate/Technical-Tip-Use-cases-for-the-diagnose-traffictest-com...

However, I would suggest connecting a computer directly to the ISP and run a speed test first to rule out ISP issue.
