uploading via ftp

hi all, hi oleg ;-)

i still have problems using the router.
when i connect my notebook (thinkpad r52) to the cable i can upload a file (350kb) to my ftp somewhere located in the internet.

then i deactivate the LAN, ensuring that there's no firewall enabled, that the windows firewall is also deactivated and that the MAC has no IP.

now turning on the WLAN, ensuring that a valid IP is assigned and calling google.de works fine.
BUT
Uploading the same file is not possible.

i'm totally sure that there is no firewall...
i also allowed all icmp traffic in the windows network properties dialog for the wlan unit.

any ideas?
i really need help...

best regards
alex

:(

please tell me something to test.
may be it's my fault again but i don't know how to test this.
the strange thing is that the transfer over LAN works fine and only WLAN has problems.

please help me :o
