Net connection suddenly goes down! after 4 weeks of use!

My Net Connection is too slow! It says in the Card that its one month with 512 KBPS. But they said that there's another one month free. After Four Weeks my net connection goes dow! When I check speedtest.net It says 400+ KBPS. So When I Open a PDF File...

from the internet, while it downloads, I can See the speed that ranges 1.2 kbps to 2.2 kbps!!!

That's not necessarily your net connection, buddy. It's the HOST. I've got high speed cable at home, and a T1 connection at the office, but if the person HOSTING the file you are downloading has a slow connection speed, then you're going to download it slow. Think about it like this: you've got a funnel into a jar. Your jar is your computer, and the funnel is your internet connection. Some guy has a funnel filled with sand, (your files) and he's pouring it into your funnel. It doesn't matter how big your funnel is; if his funnel has a very small opening, it's going to pour out very slow.

Now I know its the 3 cable! Between egypt and italy. 1 severely damaged the other two were partially cut.
