PPPOE Connection hangs up automatically in FC12

[slaith]

I have a DSL connection(BSNL) in my FC12 computer. I have free downloading after 2 AM until 8 AM so I generally start dowloading some large file(in this case, FC14 DVD) and go to sleep.

However, in FC12, my connection automatically hangs up within an hour or so. So this results in nothing being downloaded. In my last install of FC12, I noticed that after sometime, there came to be a new connection Auto-eth0 to which the computer would automatically connect. When this connection was present, everything would work fine. I once removed it, and the problems, but it came back.

Now in this fresh install the auto-disconnect problem is still there.
Please help

Also is there any CLI command for connecting and disconnecting?

PS: This problem doesn't occur in Windows
