We own a multi story building and have operations on two floors. On Floor 10 I have autonomous 1210 APs with ssid ZNDWireless running LEAP authentication with WDS. On Floor 4 I have deployed LWAPP 1242s with a WLC-4404 4.2.130 using the same ssid ZNDWireless with LEAP to same Radius/CiscoSecureACS 4.1. Between Autonomous and LWAP the SSIDs are on same vlans, etc. The goal was to be able to go between 10th and 4th floor and not care if you are on LWAPP or Autonomous APs.
I noticed sometimes the 4th Symbol PPT8800 clients associate to the 10th floor APs and have poor connectivity, etc. I was standing under a 4th floor AP with a Symbol today when the symbol associated to the 10th floor much to my suprise.
The 10th floor power on autonomous AP is set to 50mw, while the 4th floor WLC/WCS set the power level to 2 (12.5mw).
In short I'm thinking all our APs need to be either autonomous or LWAP, not a mixture in same building.
