FTP upload (upstream) problem

I am slowly but surely getting crazy

[henry0]

I run from a home office the faster cable connection that money can buy from Comcast.

My machines are plenty powerful.
I use FTP Pro
Run a wireless conn through a Comcast Linksys router.

I am allowed about 750 k upload speed (Comcast)
But when I FTP to my dedicated server (Hosted by a States wise reputed host) It's a different story!

FACTS:
My server network admin ran test while I was uploading and concluded that from its end it’s all OK
Comcast ran a test (I did see the results) my upstream speed only goes to 350 K
When uploading a dir via my FTP pro the speed starts at 20K sec then falls at 2 or 3 k sec.
The Comcast tech did set out of curiosity a single modem (not a router)
With the single modem his speed test shows the 750 k I am allowed to.
Then my FTP speed instead of falling to 2 k sec is consistent with 10 to 12 k sec.

Sorry for a long post but I need to give you the facts
Hmmm while typing the speed is down to 0.75 k sec

Is there anything I can do?
Buying on my own a good wireless router?
If so which one? But I am not a network educated person so will I be able to set it up?

I've found wireless to be a tad slow, even in house, when it comes to file transfers. I typically use a hard-line connection for bigger files. Other factors that will slow down transfers are your antivirus solutions that are running as well as software firewalls that monitor outgoing connections.

Thanks,
I was too thinking about the router FW
Wins on my XP machine has its own
PCC runs another one
I would like to disable the router one.
But I have no documentation
The router is a linksys, 4 connections with only one little antenna
It's supposed to be the newest one

How can I enter the router's FW setup?

[henry0]

I made a few searches
It might have to do with port forwarding
I found a very well written piece of info
at a site name portfowarding.com
Within the first paragraph is a link to something like "click here to learn about it"
Well-done and very easy to grasp internal, external IP and NAT concept.

Do a netstat -an and see what are the connections running on your system. If there are too many, then that is the source of your problems.

From the CL correct?
The commmand line window stays only open a 10th of a sec
So I cannot read it
Thanks

You will need to type "CMD" to get into the DOS prompt first, then type "netstat -an" so that it will not close on exit.

Results:
20 unique TCP, 8 similar TCP and 10 unique UDP.

thanks.

Doesn't seems like alot of connections to cause any slowdown in speed. Issue could be something else.

You could also try switching to/from PASV mode on your FTP software to see if it solves the problem.

I use CoreFTP which has that option on the connection settings.

This is what is mentioned on its documentation.

---------------------------------------------
PASV Transfers are transfers that are initiated by the client (you). When file listings and transfers are performed, the client connects out to the server from your computer. When PASV is not selected, the server will connect to the client. Due to the increased use of firewalls, it has become the more common choice for transfers. If you are having problems getting directory listings or transferring from a server, try selecting PASV options for transfers.

Thanks,
it is said to be PASV by default
<<<
MODE
Syntax: MODE (port or pasv)

What it does: set transfer mode to ‘port’ or ‘pasv’.

Note:

By default, transfer mode is ‘pasv’.
