I think I have found a solution to this problem - and I don't think its a bug anymore.
Trying on another router, I found it not to disconnect anymore. The router causing the problem I had no access to (since its not mine), but reading through some man pages I found that Editing the following config file: /etc/ssh/ssh_config and add this line: ServerAliveInterval 60 Fixed it for me. Or should have fixed it, but didnt. Puttin the interval to 10 instead did fix it! :) But 60 should be enough for must people. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/377322 Title: Nautilus sftp connection breaks spontaneously after a while, needing re-login to fix it Status in “nautilus” package in Ubuntu: Triaged Bug description: When I have used an sftp connection for a while - started from Places/Connect to Server or from a bookmark - it breaks, typically after an hour or so.

Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken Sometimes when this happens, my computer freezes for about 60 seconds.
