Workaround: Configure WME policy to be allowed for the wireless LAN on the wireless LAN
controller. To do this on the GUI, browse to the WLANs > Edit page for the appropriate WPAv1
wireless LAN, and in the drop-down menu next to WME policy, select Allowed or Required.
The allowed option means that both WME and non-WME clients can authenticate and receive an
IP address; for example, both Aironet ACU 6.4/6.5 and 6.3 clients could authenticate and receive an
IP address. The required option means that only WME clients can authenticate; that is, only ACU
6.4/6.5 clients.

CSCsb55937—VLAN-tagged large ICMP packets that need to be fragmented are not sent by Cisco
Aironet 1000 series lightweight access points in direct-connection mode. Ping replies never come
back when the Cisco Aironet 1000 series lightweight access point is sending requests to a gateway
from a wireless client using large 1500-byte packets, and with RADIUS override configured with
any 1p tag. This condition exists for Cisco 4400 Series Wireless LAN Controllers using
direct-connect mode, with RADIUS override enabled, the override parameter set to 1p with any
VLAN number, and Cisco Aironet 1000 series lightweight access points.
