Hello Prasanna, how are you? Have you rules of outbound in your Palo Alto Firewall? Can be filters rules reading each outbound packages making slow upload traffic.

Hi Prasanna,

              Is there a reason why your tcp-mss is so low?. I beleive that Cisco recommend 1300, maybe tweaking this on a test AP and adjusting it. I've seen issues on wave 2 AP regarding tcp-mss but only when it's not set going through firewalls and specifically on client intel chipsets.

Kind Regards Jon
