We are using a WiSM in a 6500 and everything seems to work fine. The WiSM Controllers are 10.x.x.2 and 10.x.x.3. Basically when our LAP1242AG APs join the 10.x.x.3, the 802.11a radio configuration is not available (no hyperlink) on the AP configuration page for all APs on that controller. For new ones that join the 10.x.x.2 controller, the 802.11a radio configuration hyperlink is available for those specific APs on that controller. We do not use 802.11a so I am fine with the 802.11a functionality being disabled. Anyone know where this setting is? I imagine there is a config difference between the Controllers but have been through every setting I could possibly find and just cannot figure it out...... Anyone know? If you need more clarification, just let me know.... Maybe I can attach a screenshot or something......
