I just started using Ubuntu not too long back (6.06), I everything about it's better than Windows AFAIK, except for one thing.

I noticed that my Internet keeps disconnecting whenever I download something that takes longer than 3-4 mins on Firefox to dl, i get disconnected with this error on plog:

Dec 19 14:04:43 localhost pppd[3622]: LCP terminated by peer
Dec 19 14:04:43 localhost pppd[3622]: Connection terminated.

I'm using a Aztech DSL600E and Streamyx for my modem/ISP.
