Upload probems

Hello everyone, I can’t figure if it’s just a problem of mine, or everybody else is getting it. I cannot upload a zip file (with a pack) - 150 mb. Uploading through the browser results in 17 percent, and then gives out an error, the same thing is with FTP uploadinng - no sooner it reaches about 17 percent, than it starts all over again, a new cycle. What can be the matter?
My previuos upload was just one wav track, and still the uploading process was hevy enough.
What can be done, or how much should I wait until it gets fixed?
