Xp sp1 outgoing data corruption need advice

[powr]

While sending files via ftp or over trillian, the recipient says the data is corrupt. Whether it's a zip or a jpg.
I've tried the winsock reset tool and have done a memory test.
Xp Sp1

This is xp - linksys - cablemodem.

The only thing I can think that changed was sygate personal fw update.
Aside from testing a fresh xp install any advice?
What's strange is I can receive fle via ftp without any corruption via ftp.

Any thoughts?

Thanks

It may be an MTU issue on the remote side. See:
