2.9.27 - CANNOT FTP into unit via wireless interface

We have built a pile of fresh 2.9.27 units built on WRAP boards with CM9 wireless cards.

We can FTP to the units via the ethernet port no problem.
We cannot FTP to the units via the wireless connection. (Using IE, the login prompt appears, you type in the username and password and then the FTP session just hangs)

Wireless signal/interference is NOT an issue. The same thing happens with a unit on the bench 2 metres away

Have tried Passive/Active FTP - no difference. Have tried various other FTP client programs (SmartFTP, CuteFTP) and they all throw up errors.
There are no firewall rules.

Snippet from SmartFTP:

The problem is, these units are now mounted remotely, we do not have acces to the ethernet ports and cannot install additional packages via FTP/wireless.

Am I missing something here, or is this a bug ?

I have not seen such a problem have you you used the dreaded windows internet explorer to attempt ftp??

Have tested with 3 different FTP client apps, they all hang.

Are you FTPing in through wireless with absolutely no problems ?

For the life of me we cannot get it to work.

positive that it was thoug wireless i updated the login pages for over 16 nodes all wirelessly my next questiuon is this a bridged or routed network is it ptp or ptmp??

look at your firewall(s)?
