If a connected wired client on the LAN port needs to send untagged packets out on the WAN 
port, then VLAN must not be configured on that port. 

To disable access VLAN on a particular LAN port: 

config ap lan disable access vlan <port id> <AP-NAME> // port id (1 - 4) 

On disabling access VLAN, vlan_valid in the lan_port info structure will be set to FLASE and 
vlan_id will be set to 0. When VLAN is disabled on a port, it sends untagged packets towards 
WAN and internal AP software.

To enable or disable a particular LAN port: 

config ap lan port-id <port id> <enable/disable> <AP-NAME> // port id (1 - 4) 

To display the configured values for a particular LAN port:

show ap lan <port id>  <AP-NAME> // port id (1 - 4)

To display the configured values for all the LAN port:

show ap lan port-summary <AP-NAME>

 

Following are some guidelines to remember regarding all APs.

Always try to mount the AP as close to the users as possible for best performance. Be aware of the 
environment; for example, hospitals have metal doors and the coverage can change when the doors 
close or old buildings can have metal grid work in the plaster or asbestos. Avoid mounting the AP 
or antennas near metal objects because doing so can change the coverage area.

When using the 2.4 GHz frequency, the same 1, 6, and 11 channel scheme is used as is the 5 GHz 
channel scheme. Avoid putting all the APs on the same channel, and reuse channels as you can. See 
our other deployment guides for more on this topic.
