FTP Help Needed....really badly

[IBM]

Okay, I don't know what to do...I can't FTP...for some reason it uploads a percentage of the file and then falls over...

Downloading via FTP works fine.
Uploaded just doesn't.

If I'm sending a 5KB file through SmartFTP, it'll get through about 4.5KB and then I get a timeout error with an associated 'an established connection was aborted by the software on your host machine. Connection closed.' error message.

If I go through IE to the FTP address...this applies to the three different addresses I've used on different servers...it'll start to copy, with the smallest sliver of progress appearing, then it just hangs...

I've tried different FTP clients, I've had BT out, even had the alarm system disconnected from the phone line, but nothing is working....

Please, please, please help...I've got stuff that needs to go online and nothing is working....I even tried uploading from a Mac, and that didn't work either...

Possibly a router problem? Or the server you're uploading to is having problems?

Have you had this problem before? Have you tried to ftp it from the command prompt?

[IBM]

thinking possibly a router problem, I can't see what could be killing it off otherwise

nope, haven't tried command prompt, but that would really bypass anything that a regular client or through IE would be using, would it?

[IBM]

and command prompt doesn't work either

poo

if you're going through a router with a firewall enabled, try running the FTP client in passive mode (Tools | Options | Advanced in IE, check Use Passive FTP. Not sure about SmartFTP).

[IBM]

nope, done that...I always ftp in passive (didn't realise there was an alternative tbh)...

any other sugestions? For those of you who know telephone/broadband, are there any reasons why this might be happening at those levels?
