Second question... are you using Spanning-Tree at the WLC? &nbsp;Check in <b>Controller -&gt; Ports</b>.

First question... is the controller using LAG mode?  Check in the Controller page.

Second question... are you using Spanning-Tree at the WLC?  Check in Controller -> Ports.

<div>
Lag mode on next reboot is disabled and Spanning Tree shows Port 1 STP status 'forwarding' and Port 2 STP status 'Disabled'

Ok many thanks Ill give it a go. <br />
<br />
Just for the future if I need to swap the modules to port 2 where do I do the configuration ?<br />

Have a Cisco WLC 4400, that keeps dropping off our business network. The light keeps going out where the module connects to the WLC from the network via a network cable I.E. WLC Module&gt;Ethernet cable&gt; switch.<br />
<br />
I have too regularly replugh the module back into the controller for the wireless to kick back in and the light come on. I have tried another cable and now think it maybe the module. Someone suggested re-configuring the WLC to the 2nd port to see if the issue confirms it is the module or just port 1. Good idea.<br />
<br />
How would I do this ?

Cisco Lan Controller Dropping Off

Wireless networking is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure. The key hardware components of a wireless computer network include adapters, routers and access points, antennas and repeaters.

Wireless Hardware

Wireless networking is anything related to the transfer of data between two (or more) devices without the use of a physical connection, ranging from getting advice on a new Bluetooth headset to configuring sophisticated enterprise level networks.
