Help, internet connection up and down.

[mystvearn]

I am using a DSL line with the Aztech 305E external modem. This morning, waknig up I saw my connection disconnected. I am online 24/7. I don't know if some lightning hit the modem. My internet connection from max, then zero, then max again. Tried all applications, its like that. Bittorent, FTP, download anything, it will become like that. Even loading websites will stall during this period. I am just afraid that I loose packets, and have to refresh everytime.
here is the picture of what I meant.

Is there some way to fix this? I tried the reset button, before this it was worse, longer lag times. Then I tried the reset button again. This is the most I could get from the modem.
Help

Also if anyone know a better bandwith/time monitor that I can use to really determine how long the lag, the peaks are please tell. The pictures are just from the azureus bittorent activity layout.
