Wireless Issue Sudden drop in signal strength

[arjun-hegde]

Hi there,

Our Wireless Setup(Cisco 1242 AP with Cisco 5508 WLC) was running without any issues for two year lately over last two months there are issues with Signal Strength and our ha

ndhelp devices are unable to fectch needed data from the application server in the network. Please advice what could be the possible cause of this issue.

Secondly for your information I have attached screenshots captured from wireles controller, metageek tool for you to recommend me some resolution. Below is a ping response which I received while i tried to ping the Gateway over wireless network.

Pinging 192.168.3.10 with 32 bytes of data:

Hi Arjun,

I would suggest that you do a site survey for the location and do a spectrum analysis. There are probably some RF sources that merged to the scene without being noticed. Find those sources and eliminate them. That will probably get your issue resolved.

Thanks for the information. What about the ping responses is this normal to have such fluctuating response times. We had ping test just staying below the accesspoint antenna.

Check to see if there is a duplicate IP address as this could cause the spike in ping times.
