Dear All,
We have Cisco Wireless controller running with the firmware Software Version 7.0.220.0 and we often face issue with new Apple Iphone with IOS 7.0 face issue when they try to login to the wifi-ssid, its gets connected and disconnected.
Moreover, we are only getting a maximum speed of 50Mbps using the wirless controller when the LAN speed is around 90Mbps, kindly advise on the same matter.
I have been reviewing all the post mentioned here and could not find any suggestions.. following wirless access point snapshot has been attached with the discussion..
Do we need to upgrade the IOS to the recent available ?
Hi Shameel,
Speedwise your observation is normal. You can't get wired speed in wireless (wired is full duplex & having no interferences, but in wireless, it is halfduplex & always have some sort of interference/noise). Higher througput in wireless is depend on your AP models, frequency band (2.4GHz or 5GHz) & number of SS (spatial streams) your client device can support. Below chart gives some idea about Cisco AP model & max supported rates.
Irespective of that, it is good idea to upgrade your controller software. I would recommend go for 7.4.121.0 code. Refer below compatibility matrix depend on the AP models, WCS/Prime & MSE availability of your network
Here is the release notes for 7.4.121.0 code for your reference as well.
