I have Cisco Wireless Controller: 4402. Current Software Version: 184.108.40.206. I want to update current software version to AIR-WLC4400-K9-7-0-230-0
I download two files from Cisco website: AIR-WLC4400-K9-7-0-230-0.aes and AIR-WLC4400-K9-7-0-230-0-ER.aes.
I try to firstly upload the AIR-WLC4400-K9-7-0-230-0.aes to the controller by tftpd32 or 3CDaemon. However, when the data has been transferred to 66MB. Stop. I get the error from tftpd32
Connection received from 10.203.220.200 on port 7714 [28/02 20:20:14.195]
Read request for file <./AIR-WLC4400-K9-7-0-230-0.aes>. Mode octet [28/02 20:20:14.196]
Using local port 53336 [28/02 20:20:14.197]
File <.\AIR-WLC4400-K9-7-0-230-0.aes> : error 10054 in system call recv An existing connection was forcibly closed by the remote host. [28/02 20:20:52.521]
I know maybe it is because of big size file.
What shall I do to handle this problem.
5.0 has the large tftp fix, so you should be able to directly upgrade.
I would try rebooting the WLC, then doing the transfer again.

the version of tftpd32 I use is 4.0. Where can I download the 5.0? I google it. Not available.
tonight I will reboot the controller to have a test
If you still have issues after the reboot use 3cdeamon I use 3cdeamon with no issues.
I reboot the WLC. However, it is still at the issue.
I tried 3cdeamon. I get the error code "66MB, Got socket error. Aborting!Code=10054"
I tried tftpd32. Also problem.
I reboot the controller. it is still at the issue.
