Although it does accept it in the setup wizard, you cannot change it in the vap list later on, it will throw a popup telling you there's an invalid character.
Anyone's got a solution? I'm running firmwarte 126.96.36.199
The inconsistent for the "space" character from Wizard and Web GUI was known before the release of the original firmware version 188.8.131.52. It was too late to have the fixed put in that released due to long process of GPL process. This issue will be fixed in the next available MR firmware for both models (WAP121 and WAP321), no firm date yet, however, it is soon. Thank you for your comments/inputs and I always appreciated your business with Cisco.
