Kendt- We have a "strongly encouraged" (we are a public school district) BYOD program in grades 6-12 using 2 x C4110's running 8.11.11.0003, 3610 APs, and NAC. To get the AP Multi-edit settings to stick you have to always set Admin Mode, Radio Mode, and Antenna Selection. I think there was some talk about changing this but I still have to set these three settings for my settings to stick. I am still on 8.11.11.003. Do not leave ATPC Enabled and Auto Channel in Active Mode. You should set these once, let the APs figure everything out for an hour, then disable ATPC and set Dynamic Channel to Monitor. You do not want your APs switching channels and changing power settings all day long. This will drive clients crazy. I set my minimum transfer rate to 24Mbps. I have an AP in every "teaching space" and the clients should all connect at that rate and not decide to jump on some distant AP or not roam when a kid switches class. Also, I only have Legacy, WMM, and 802.11e enabled in WLAN Services > VNS Name. I also have Flexible Client Access Enabled and set to Mostly Airtime.

We have had reports of client connection issues at one school with a heavy Mac deployment in a group of adjacent classrooms. Controller - C5110-2 firmware 8.31.03.0011 APs - 3610 - 1 per classroom Clients - MacAir OS X 10.8.4 (google search show other folks having WiFi issues if there is heavy channel interference), 33 per classroom. SSIDs - 2 deployed, one hidden, both using NAC/RADIUS for authentication Topology is Bridge@AP for these authenticated clients I've tried to push the config recommended from the help pages, but for some reason bulk AP radio configs are not sticking (I changed several of the ones listed below but looking at the current config they are not active). I did enable DCS in active mode and will be onsite to monitor today - current radio configs are: Radio 1: Admin Mode: On Radio Mode: a/n Channel Width: Auto Guard Interval: Short ATPC: Enabled Max Tx Power: 24 dbm Min Tx Power: 8 dbm Auto Tx Power Ctrl Adj: 0 dbm Channel Plan: All Non-DFS-Channels Ant Selection: L/M/R Advanced: DTIM Period: 5 Beacon Period: 100 RTS/CTS Threshold: 2346 Frag.

Thanks for any info!
