Hi all, anyone experienced the following.
Large campus network, running 6.4 code.
Intermittent poor internet access only on 1 SSID (eduroam) and seems to be only on 205 series AP's. All other SSID's connect without issue.

This issue from my testing is only seen on AP205's.
Make the following change to “AP system profile” of all the AP-groups and change the “SAP MTU” size to ‘1500’.
Seems by default no value is set. Making this change had an immediate, positive effect.

Hi Tim, I believe this is 802.1x, other SSID's are the same I believe. Has worked for years it is a recent issue, seems to be with 2xx series AP's only.
Stunshot, please open a TAC case. This could be a bug or a configuration issue, but it is very hard to tell from the limited information that you provided. TAC should be able to rule out a few things and ask you about others...
