FTP Selective Access after Router Installation

I recently installed a router, after which, I can access only 1 of 4 FTP sites that I previously had access to. Of the remaining 3, two (both at the psych.utoronto.ca server) provide the message:

"Connecting to (psych.utoronto.ca) -> IP: 128.100.69.32 PORT: 21
Connected to (psych.utoronto.ca) -> Time = 46ms
Socket connected waiting for login sequence."

and the third one allows me to connect but I am unable to view any of the files held on the server. All are secure sites and require passwords of which I have. Any suggestions? Thanks.

Try to update the firmware of your router.
