We are currently testing the 1200 access point with the 802.11a radio. In testing the performance and distance, it appears that the radio card will not drop down to a lower speed to increase the distance. It continues to run at 54Mbps. Because of this, the distance is very poor. In fact, at about 5 feet, the Cisco Aironet Status Meter is showing about between 50% and 60% signal strength. As you move away from the access point, the signal strength continues to drop and link is lost at around 60 feet. Anyone have an idea why the speed doesn't drop on the link and keep the link up at this distance?
You may want to check your configuration for the "optimize radio for throughput" section and make sure that it is not configured to only use 54 mps as the throughput range. If it is then of course you will have issues when moving further away from the AP. The following URL I found should help you with the config.
I'm seeing about the same strength at those distances. Ours does drop the rate, although it seems to be on the verge of losing the signal prior to reducing it. After using the 350, this one's real disappointing as far as distance goes.
