7926G works over 802.11g but not 802.11a

                   We have a 1600 AP and can regsiter phones fine over a 802.11g. But when using the 802.11a it never gets connected and the phones signal light is blinking with yellow flag off/on. Other laptops though connect to the AP on 802.11a. What could be the problem? and /or where to start?

7926G works over 802.11g but not 802.11a

Is the AP1600 in unified or autonomous mode?

802.11d (world mode) is required when using 5 GHz (802.11a) as only a single model for 7926G is offered to all around the world.

For 2.4 GHz, channels 1-11 can be scanned as those channels are common around the world.

802.11d  is enabled by default for a unified AP when registered to a Cisco WLC,  but it is not enabled by default for an autonomous AP.

So if using autonomous AP, ensure you enable the country code.

See the 7925/7926 Deployment Guide for supported country codes.
