Rogue AP

Hi all

I work in a company where we rented offices and we offer internet service for all (VOiP and internet). The place where I work has 2 buildings and each building has 2 Cisco WLC 4400. We have about 100 Acces point in total (connected to the WLC) to give free and public internet service . The problem we have is that companies connect their LAN AP and makes the free wireless network go very slow. If we enter to the WLC appear around 300 Rogue Aps per building, it's a lot!. We think that the problem of slowness is this. Is there any possibility that our APs not see the APs of the other companies? How can we fix the internet speed of our APs? 

thank you very much

Depends on a lot of things: 

Depends on a lot of things: 


1.  What model(s) are your APs; 

2.  What firmware is your controller running on; 

3.  What radio is severely affected?

Hi Leo,We have the Cisco

Hi Leo,

We have the Cisco Aironet 1020 series

The firmware is

The Rogue Aps detected have around 82-95 RSSI and 1 to 13 SNR. 

All Aps are in DCA channels 1,6 and 11.

When more no corporative APS are connected more slowness have. Also we have fluctuation and sometimes close sessions. 


Thank you very much

The signal strength of the Rogue APs doesn't affect any of your issues. 


What you and your management should think about is the age of your APs.  1020 is long, long End-of-Support.  The firmware you are using is ... ancient.  


1020 supports 802.11b.  So this means you're maximum 11 Mbps.  And when everyone says 11 Mbps, this is expressed in HALF duplex or one-way traffic only.   In reality, you'll be lucky to get 5 Mbps.  


Now, let's say you've got one person with a brand-spanking-new iPhone 6 ... One guy alone with a smartphone can really, really slow down your wireless.  


If the model of your AP is that old and the firmware of your WLC is equally as old, then I shudder to think about the age of your LAN/WAN infrastructure.  This also means any opportunist salesperson can potentially sell you EVERYTHING: 


1.  LAN & WAN:  Maybe it's time to upgrade your current LAN switches because high-speed 802.11n and 802.11ac wave1, wave 2 will require 1 Gbps.  802.11ac wave 1 and wave 2 would benefit if you have 10 Gbps uplink to core network. 

2.  Security:  IDS/IPS and Firewall.  If you've got guest wifi, you'll need to incorporate these. 

3.  Network Monitoring:  If you've got executives who like to look at performance numbers, colors, graphs, etc. then CPI is your tool to manage your LAN/WAN and wireless as well as generate mind-numbing reports for bean counters to salivate upon. 

4.  Wireless:  You need to upgrade your APs.  You will also need to upgrade your WLC.  No question about it.  

5.  IP Telephony:  If your LAN supports PoE/PoE+ then IP telephony is your best bet.  You can even link IP telephony with wireless as Cisco has two models of wireless handsets:  792X and 9971.

6.  Video Conferencing:  Do your executives like to do video conferencing?  You can also "link" this with IP Telephony as Cisco has a few desk phones which can also do video conferencing. 

7.  Instant Messenger:  Cisco is pouring a lot of resources into the improvement of Jabber.  

8.  Digital Media Streaming:  Does your company consider putting some kind of network-based Digital Media Streaming in your office?
