Are there any tricks with u/g to 4.1.185.0 with WiSM). It's size it 37,511,776 bytes.
Current s/w is 3.2.171.6 on WiSM (it's new & came with this.)
TFTP keeps dying at exactly the same bytes at every attempt. I've tried 3COM & Pumpkin TFTP servers & same error.
I believe there are known issues with TFTP & the 32MB boundary. Last time I hit this with a Sup32 I had to use FTP but I don't think WiSm supports FTP, right?
I succeeded in u/g to 4.0.179.11 who's size is 27,426,896 bytes.
I would still like to u/g to 4.1.185.0.

PS:You should be good to go with TFTP32. Many others have used this successfully for this upgrade.

Hi Rob,
Thanks for your encouraging words.
I successfully u/g to 4.1.185.0 who's size is 37,511,776 bytes. Hence the greater than the TFTP 32MB threshold.
Not only do you need a TFTP server which supports > 32MB (TFTP32 worked for me) you need to be running WLC s/w which supports > 32MB transfer. The cisco doc refered to above spelts it all out.
I started at 3.2.171.6 (what WiSm was delivered with). This does not support > 32MB transfer, so I went to 4.0.219.0 size 30,498,252 bytes. then went to 4.1.185.0.

The TFTP standard has an limitation on files greater than 32MB however several of the TFPT servers can handle this. Try using the newest tftp server from SolarWinds (free) or version 3.0 or later of Tftpd32. If you have a WCS version 4.1 you can use this for upgrading controllers as its builtin tftp daemon supports files greater than 32 MB.
