Summary: I set a few of these up in standalone mode via the IOS console. We're using an HP switch with PoE to power them. This was my first IOS device to configure, and I found the process straightforward. I also like that these can switch to a managed mode for use with Cisco wireless controllers if we need better wireless client management and hand-off.
Summary: Would have given this 5 stars but the price tag. USE the channel scan feature 5-10 times to find a clear channel and this thing delivers the goods. We are covering 7000 sq. ft. with partition walls, no drops, great throughput, etc in an office building where you can pick up 20+ SSIDs easily. Works fine with generic POE adapter as it meets the a/f standard. It has been running for months, no issues, not even a power reset.
Summary: Setting up a Cisco Aironet device is not for the fainthearted. These devices are primarily designed to be used in large enterprise applications where a control system does all the configuration and management of the device for you. That being said, it is possible to use the standalone version via command line configuration, or built in web server. Just don't expect the configuration to be easy or simple.
