Long story short, I was able to stop this error by allowing "Key Management" to be Both (WPA-2 & WPA).

Really?! Simple as that? i will check it on-site if the client will keep complinig - do u know maybe why it's happning only in ubentu?

(WPA-1 isn't part of 802.11n....and usully mixed mode making more problems)

Re: InstantAP + Ubentu clients ,once in a while keep getting an error

I looked back in my notes and my problem was actually reversed. I had all devices on a combined WPA/WPA2 network and i was getting the MIC error.  With TACs help we narrowed down the devices to the cisco phones and the ubuntu devices.  We ended up moving the phones to a dedicated SSID with WPA-TKIP and set the main SSID to WPA2-AES only, at this point the phones and the ubuntu devices worked.  I did update the firmware on the phones and the drivers on the ubuntu devices while in the process so that may have had something to do with it.  I can tell you that TAC focused on the client to resolve this issue, devices driver, firmware, key length, odd characters in the key, etc.

I noticed that your Instant network has an upgrade avaliable. The first thing TAC will ask you to do is upgrade to the latest release.

Hi,

1. Can u please tell what in the end solve your ubentu issues?

2.In my lastest visit on site (earlier this week)  I already upgraded the client VC to the newest version:

6.2.1.0-3.3.0.2_38733

3.today I also change it to mixed.... And it's just made more issues for other clients types (802.11n is WPA2-AES only! All the others lower encyption methods  usully making problems.That's why it was a surprised that u offered that - but even due I tried it..And got more problems)

 

any more ideas?  Please advise..

Client still compiling. (ubentu clients,different chipsets keep disconnecting..Keep asking for key....)

 

Thanks in advance.
