Performance of my wireless network is very poor, pings from wireless clients to the management address of the controller and client default gateway flap intermitently.
The set up is a WLC4402 connecting to a 3560 Multilayer Switch(SwitchA). I am then trunking the necessary vlans from this SwitchA (Management Interface VLan 162 and WLAN Clients Vlan 164) to another 3560 (layer 2 except for management address Vlan 1) lets call this SwitchB. Then all my LAPs (1252G) connect to SwitchB.
Managenet Interface ip- 10.110.130.2 gateway 10.110.130.62 (SVI on SwitchA) Primary DHCP server (10.110.130.2) Secondary - none
AP Manager- 10.110.130.1 gateway 10.110.130.62 (SVI on SwitchA) Primary DHCP server (10.110.130.2) Secondary - none
Dynamic Interface - 10.110.129.21 gateway 10.110.129.62 (SVI on SwitchA) Primary DHCP server (10.110.130.2) Secondary - none
Client DHCP pool - 10.110.129.1 - 10.110.129.126 (configured on WLC) - Gateway is 10.110.129.62 (SVI on SwitchA)
Virtual Interface - 188.8.131.52
Service port - 10.195.1.1
Please note that APs are joinning the controller and clients are receiving addresses, the problem is just that the performance is poor even when standing beside an AP.
Hi All, the problem has been resolved. It was due to mismatch on the radio properties of my Wireless NIC. I enabled US and GB country codes so that I could manage the different APs on my network and then changed some settings on my Wireless NIC since then performance has been great.
Does this sound similar to what you were experiencing and should I receive solid non intermittent pings? At first I was questioning whether it was just a normal thing on CIsco wireless. I could use more info on exactly what settings you set on the client side. And any info you have on what you have seen as normal.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
