I took over a client that has several Cisco 1240AG AP's. Currently they are running the 2.4-GHz 802.11g mode but I see from the dashboard it has a 5-GHz 802.11a thats just disabled. I'd like to use the 5Ghz as well. I found the below on the specs for it on Cisco's website. My question is do just need to enable it? DO I need a different antenna or anything or is it just turned off. DO I need to create a new VLAN for the 5ghz network or will it transmit both?
It features dual-embedded modules-a 2.4-GHz 802.11g module and a 5-GHz 802.11a module. Both radio modules feature dual RP-TNC connectors to allow users to select from numerous 2.4-GHz and 5-GHz diversity and nondiversity remote antennas.
