FileZilla 3.5.0 takes down my wireless router

Description

after update to 3.5.0 (was working fine between same two machines a couple of days ago - only significant change is FileZilla client upgrade) connecting to one of my servers takes down my wireless router. By which I mean it kills the connection between client machine and router, and also connection between iMac (different machine) and iPhone.

Steps:
1) wireless connected fine on all three devices. these are the only devices connected to wireless, and client machine (Win7 laptop) and iMac are not using DHCP (iPhone is)
2)Attempt connection to a specific server (which happens to be running FileZilla Server - message logs from both ends of connection at bottom of report). Initial connection fine, but on the PORT step connection hangs. As I say, this worked fine between the same two machine in 3.4.x just a couple of days ago
3)All three devices are no longer able to connect to wireless.
4)Physically reset wireless router
5)Rinse and repeat (6 - 8 times before filing bug report)

Other notes:
1) windows command-line ftp works fine to drop files between these two machines

Also, FWIW I would have put this in the forums first except that you won't let me register for the forums with a gmail account. I can understand the issues with forum spam - I run a couple of forums for my day job as a web developer so I'm familiar with the problem - but I use gmail for all my day-to-day emails and don't want to have to check one of my lesser-used accounts just for filezilla stuff - using your forums for pre-ticket troubleshooting for *your* convenience isn't that important to me.

If you really want folks to use the forums before creating tickets you should make it easier to create a forum account, not harder.

By specification, an unrelated application running on a network host cannot bring down a router. If it can, the router has a flaw. So please update the router firmware. Maybe it has some (broken) security options? Try to disable them.

I do not see this is a bug in FileZilla itself.

Note: See TracTickets for help on using tickets.
