Hi Guys, new here!
We had a wireless network installed a few years ago which the support has now lapsed on. We are having a number of issues with throughput...
Managed with Cisco WCS
Our G devices report to be connecting at 54G, tests with iperf show throughput of ~16Mbps, N devices connect between 21.5Mbps and 72Mbps and also only show around 20Mbps throughput with iperf. File copying from servers gets around 2.5Mb/sec transfer rates. There are no obvious alerts/events on the kit in WCS, I have rebooted a number of AP's to no avail. inSSIDer shows the AP's and their 300Mbps capability, but my N devices don't get anywhere near that speed, even when i'm stood directly underneath it with a device. I believe it is a dual band setup, as each AP has a seperate profile in WCS for b/g devices and a/n devices. The nics's in the devices are dual-band intel 6200's.
SSID's are secured with WPA2/AES/MAC Filtered, 802.1x RADIUS auth, linked with Server 2008 R2 DC via NPS
Could anyone shed any light on a potential problem or advise on troubleshooting techniques... this isn't really my area of expertise!
