RF & particular SSID issue...

[shrinivas.k]

Hi All,

We are expereincing some strange problems.

1. One particular SSID's is appearing very low single strength & rest 2 SSID's are having good single strength from out of 3 SSID's advertised in one LAP.

2. Another issue is one of the particular SSID is not working from out of 2 SSID from  particular AP......in this issue client getting good single & we verifed WLAN settings are fine in the AP, also with the same WLAN settings this SSID Is working fine from other AP's.

Please let me know, if you have any idea in this issue.

Thanks,

Shrinivas

Hi Shrinivas,

What model of WLC and IOS you have got?

It may be that your 3 SSID's are not advertised on all the AP's and that would be the reason why you are getting low signal from one SSID and when combared to others.

Please verify your AP group setting and confirm if all SSID's are advertised on all AP groups.

I would recommend to check if all APs are indeed broadcasting this 'low strength' SSID (inspite all APs been in the same group). Check the BSSID of the APs with inSSIDer or similar tool and verify that indeed APs all APs are broadcasting all SSIDs.

HI Vlad,

Another thing which you could try is to connect to both SSID (one at a time) from the same location  and verify if both the times you are connecting to the same AP. With this you will be able to verify if the both SSID signals are from same AP. This is really a trial and error methond. Also you may install netstumbler and verify the signal strength which you are receiving from each AP at given location.

Check your AP groups or even RF group.  Starting with 7.4.100.X, RF Group was introduced.
