Austin,Thanks for a very, very useful post.Have you ever seen a situation where the airport utility says "No beacon for too long time" and then drops out?Thanks
Meesick,We're lacking some detail here. When the clients move away from the network for more than 25 seconds, they cannot get on again? What kind of encryption are you using? If WPA2-AES, did you enable "Validate PMKID"?
Can options like "key message retry" and others discussed here be changed in Instant Access Point? I didn't find any relevant options in the IAP CLI.
Anyone ever had any issues of a client dropping off a couple times a day? I'm at an iMac, later model, running 10.6.8, several times a day my wireless will drop, and i'll get disconnected from my chat programs. I'm 15 feet from an AP 105 under low load.
I'm guessing it might be happening when the AP changes channels? If its happening to me, i'm betting its happening with others in the building too. Just want to figure out a solution before it becomes a problem.
You can enable Client Aware on the ARM profile. That will prevent the AP from changing channels while you are connected.
But I would put your client and the AP you are connected to in debug mode on the controller, and after it happens look at the logs. Just to be on the safe side. It might be interference.
What kind of encryption and what version of ArubaOS?
type "show ap arm history ap-name <name of ap>" to determine when that AP changed channels if you suspect that is what is triggering it.
Also, what Aruba OS version are you running. I just saw a bug fixed in 126.96.36.199 which could explain your issues.
A performance drop observed on AP-105 with 20 MHz HT enabled when connected to Mac clientshas been fixed. This performance drop was seen in the form of 10% to 13% packet loss on pingsto the default gateway on the controller.
Running the latest version, 188.8.131.52 -
Looking at the settings in the ARM profile, client aware is already enabled. It's not really a performance drop issue, its a connectivity drop. The client would just drop connection, then come back. Any chat clients or anything that relies on a constant connection, like SSH, drop out and disconnect.
I put my computer in debug mode and checked it again after a drop. Nothing jumped out at me in the log, in fact, I didn't see any new messages between when I was connected and when I reconnected.
Attaching my 802.11a ARM settings -
