Cisco WLC 3700 Performance Problem

[Ben Duff]

Hi,

We have a Ubiquiti UAP-AC-PRO that we're testing, the performance of this is significantly better than a Cisco 3700 we have connected to a 5508 controller. On a file transfer we see the Ubiquiti perform twice as fast on two different 5Ghz clients, one with an older Intel 6205 (N) and one a 8260 (AC). APs are in the same location and I don't believe any enviromental issues are occurring. The connection speeds appear the same on the client when connected to the AP.

Our question is what configuration have we got wrong on the 3700/5508 as clearly something is wrong? On the controller the older 6205 client shows a connection speed of m7 and the newer 8260 shows m9 ss2, is this the problem? In Windows it shows a connection of 300/866.

Thanks
Ben

Hi Ben

As you figured out earlier, this could be a software bug.  Try different applications (eg - iPerf) to see slow speeds only for file transfer.

Here is some of performance testing I have done with 3700 sometime back

Will do some futher testing to confirm.
