In one of our doctors offices, where we have 3 wireless laptops we're contantly having issues in the morning as the doctors arrive. The access point will begin generating errors: Received TKIP Michael MIC failure report from the station 000f.8f42.361a on the packet (TSC=0x0) encrypted and protected by pairwise key.

This basically locks the entire access point down and no one can connect until we reboot the access point. We've replaced the WAP twice already, also replaced the switch. Same errors. Each laptop is a different make/model. My config is below.

One of the laptops is not configured properly or has a poorly written driver. Upgrade the wireless NIC driver and recreate the connection. You could turn the wireless access on each of the laptops and test one at a time turning them on until you find the culprit/s that are causing the problem. You may also want to upgrade to 12.2.15 IOS on the access point if you haven't already.

Since we bought these through CDW - how do I go about finding the newer IOS? Cisco's website seems to be totally locked down?

Find out what the warranty was that you got with them and create an account on Cisco's website using the serial number. If it's under warranty, then you should have access to download the software if they are new. I think the warranty is 30 to 90 days or something like that.
