View Full Version : FTP problems with wireless connection!

10-24-2006, 03:00 AM
have had a long standing problem with FTP connections over a wireless network from my Powerbook.

The facts:
i) I am running OS 10.3.9 but have had the same problem with 10.4.8 on the same machine.
ii) FTP works fine from same machine using dialup or wired ethernet connection and same FTP client.
iii) FTP works fine from other machines on the same network using the same router and FTP client.

The problem:
FTP simply won't work reliably when I am connected wirelessly, the same problem persists regardless of the client - I use CuteFTP Pro for mac but have the same issue with other clients e.g. Fetch, Transmit, and even the terminal!

I can usually manage to connect to the remote FTP server and often view the directory but any kind of FTP transfer, down or especially up, results in a long hang which normally just sits there for ages doing nothing like it is being blocked. Since all other variables seem to be removed through testing, I can only assume this has something to do with the OS running on a wireless network.

Has any body else had this problem - or know of a potential solution as copying to a PC just to FTP is doing my nut! - Incidently, if I FTP into the powerbook from another machine on the network it all works fine - it is only when I try to FTP out to another server via a wireless connection that I have this problem.

Nice one.

Do you have problems on this computer with large downloads over http as well? That might indicate an MTU problem.

Are you set to use Passive FTP in System Preferences > Network > Show: Airport > Proxies tab > Check "Use Passive FTP Mode (PASV)"?

Active FTP vs. Passive FTP, a Definitive Explanation (http://slacksite.com/other/ftp.html)

Are you behind a router? What ports do you have open in that router? What ports are forwarded to this specific computer from that router?
