Apple device seemed to have internet issue after roaming between AP in the same SSID

[MICHAEL TJANDRA]

hi all,

I encounter something strange lately.  for Iphone device - only for Iphone, it needed some time to recover the connection to the internet.  I can't find anything in the logs why it reacted this way.

The iphone lost connection needed a while to recover and sometimes needed to re-join.

Clean air status saying : issue.

Controller is : 5508 series with software version : 8.0.121.0

AP : AIR-CAP3502I-S-K9

I wonder if anyone encounter the similar issue.

thank you.

When this issue noticed ? when did you upgrade 5508 to 8.0.121.0 code ?

Below is the recommended code in 8.0.x  release (8.0MR3)

hi Rasika,

The issue started about 2 weeks ago.. the upgrade to the version was done actually about 6 months ago.

Thank you.
