High number of Rouge AP on Cisoc WLC 2500 dashboard

[ammar taha]

Dears,

I have on Cisco WC 2504 with 7 APs , I have an issue , the signal is appear on the end users but always the end users have disconnect to the gateway and internet ( multi-times users have ping request time out for gateway and Internet every days), 

As the attached file of Dashboard , I see the rouge of AP are 90 ,

Kindly any support ?

Best regards,

Timeouts to the gateway is typically due to client driver issue.  Don't assume it's due to rogue AP's around your space. Also look at if your clients are mostly on 5ghz, preferred, or on the 2.4ghz. You can use client band select and also bump up the value from 2 to 4 or 6 until you get a good ratio on 5ghz.

Thanks Scott,

How I can change the Client band select and bump up value 2 to 6,...) is from WLC or from client windows ?

This is done on the WLAN first!  On the WLAN advanced tab, enable client band select. Then in the tab WIRELESS | ADVANCED | BAND SELECT change the probe cycle count to 4 and then later to 6 and see if you get a better ratio on the 5ghz.

Wow Scott you have so much patience responding to these posts where people don't read the manual or use Google.

Bob,

When I was consulting at CDW, it was the same. There were many customers that just wanted things to work. Even being internal now, there are folks whom just want the answer instead of researching and actually testing the feature or change. This is a reason I miss consulting:)  I have to have patience working internal, I just have to smile.

Oh I didn't know you work at Cisco.  Well anyway, great job.

I'm not at Cisco... at Microsoft.

I changed to 6 but still the issue , client's have disconnected randomly to the gateway ? and how I can force the WLC is working only on 5 Ghz ?
