I have bought a new 1921 router (IOS :C1900-UNIVERSALK9-M), Version 15.1(4)M4) and connect my ADSL link to it. After router connection i am facing frequent disconnection during uploading any file through coreFTP though i haven't face any problem in downloading any file from FTP server .
if i connect back the ADSL link directly to the PC there is no problem in uploading or downloading.
I have checked the MTU configuration on router and PC (Windows XP) still the same problem arises.
Please find my Router dialer and inside lan interface configuration.

Hello,
I do not see any obvious issue with your configuration. This must be something quite minuscule. A couple of suggestions:
