I don't know what kind of equipment you have either at home or work
but it seems there are some routers that will give you the exact
symptoms you are seeing. For example, here is a conversation I ran
accross where someone else is having what seems to be the same
problem as you:

I have just connected my new DI-764.
All seems fine, except my SSH sessions now get disconnected after 10
or so minutes of inactivity (SSH is like an encrypted version of
Telnet)
Prior to using the DI-764, I was using a switch connected to a PC
running windows 2000 'internet connection sharing' and had no
problems (idle sessions
never timed out).

Dear Chris,
Products: DI-764
Operating System: Windows XP Pro
With our routers, idle sessions on any ports are dropped to free up
resources for other connections that are active. To keep your SSH
connection open you
should configure your client to send some sort of keep alive so that
there is always traffic going through the connection.
Thank you for networking with D-Link.
Sincerely,
Matt
