My company recently went from an old airspace 4024 with firmware 3-2-195-13 to a new 4402-50 running 4-1-185-0. Using Option 43 in DHCP allowed the new 4402 to see the AP's on different VLan's and Subnet's and issue IP addresses to the AP's and clients. It appears several of the AP's have not pulled down the new firmware and are stuck at 3.2. I have rebooted the AP's and tried multiple other tricks. Is there a Cisco utility that will allow me to update these LWAP's via mac or IP? Any suggestions would be appreciated. I'm sure I could go around, collect these AP's bring them back to the 4402's location throw it in layer 2, reboot and they would take the update but that is too time consuming of a process.
I know from experience that the 1131 and 1230 APs can't be upgraded from 3.2 to 4.1 because a 440x controller can't be upgraded from 3.2 to 4.1.
Check the release notes on the 4-1-185 software.
"Important Note: If you are running any lower version than 184.108.40.206 in 4.0 stream or if you are running lower version than 220.127.116.11 image in 3.0 stream , please upgrade the controller to 18.104.22.168 or higher for 4.0 stream and 22.214.171.124 or higher for 3.0 stream before loading 126.96.36.199 image."
They are suggesting that if you want your APs to upgrade from their current 3.2 software you must upgrade them to 4.0.x software first. Then you can upgrade to 4-1-185.
I would downgrade the controller software and see if the 1000 series APs will run the lower version. Then I would upgrade the controller to the latest software and verify that these APs are running 4-1-185 software.
Hope this helps.
