There are no specific problems that I am trying to resolve, I am only looking at optimizing performance. This network has a 3200 controller running firmware 6.1.3.3, and managing 32 105 APs. There are three SSID's, two internal, one guest. There are typically 175-225 clients. Clients are very late model devices, including iThings, Androids and Windows7 laptops.
Examining realtime statistics yesterday morning, there were 217 clients at that time, and all guest clients were b clients; most were b-HT. These devices were iThings and Androids; no Windows devices. There were also iThings on the other SSIDs, but they were a-HT or g-HT.
At the moment I am writing this which is about 24 hours later than yesterday when I was looking, there are 176 clients, all are g-HT, ecxcept for two g, and 9 a-HT clients. There are no b or b-HT. The guest_vap is set to allow band g only; this has not changed since yesterday. The options on the 3200 controller are g, a or all.
Thanks.
