ZD 1100 and 7373 APs: Very slow throughput
I have a zone director 1106 (running 18.104.22.168 build 101) connected to 3 7363 APs and have very low throughput over the wireless network. This is both for internet traffic on TimeWarner Business Class with 200mpbs down and 20mpbs up and over the local network. Wired transfers over the local network are 112-115MBps. Wireless speeds are in the kilobytes. Anything but the most basic internet browsing is maddeningly slow.
I reset the ZD to defaults to start over and have the same problem. I have a support case open in which we spent a few hours on the phone troubleshooting and support is now looking at logs and such. Support created a test WLAN on one AP and made a few changes to that WLAN that got some increase in speed but not much and certainly not anywhere near wired speeds. IIRC, we might have seen 6MBps on this test WLAN.
While I'm patiently waiting for support's response, I'm hoping the community might have some thoughts or suggestions on what to try or look at. I know Ruckus is supposed to just work but, well, it doesn't. Thanks in advance!
