What does below mean? 

vap-0 AP PS: AID=4335712 select next response

It's shown many.

I know that this is due to poor NAT performance on standalone APs.


Anyone have good idea?

Hi Jeronimo,

What version of firmware is your AP using?  If it's the Standalone (100.x.x.x) firmware then either ensure you are on the latest version or I would recommend upgrading to the Unleashed firmware, which is much more feature-rich than the Standalone version.

Thanks,
Darrel.

[hyosang_choi]

It.s 104.x.

[DarrelRhodes]

Have you tried installing the Unleashed firmware, performing a factory-reset, re-configuring and seeing if the fault persists?

Thanks,
Darrel.
