My "problem" is that Ubuntu One upload rate goes from 30 kbps to 15, then to 8 and 4 kbps, then again goes to 30, 15, 8, 4 kbps... what's wrong?

I'm using Ubuntu 12.04 LTS AMD64, connected to the Internet through an Android Wi-Fi hotspot.

Sorry for my bad English.

Thanks.

The pattern you describe sounds like your upload is being throttled, but not smoothly, which is why you see these bursts followed by very slow speeds.

connected to the Internet through an Android Wi-Fi hotspot.

  • If you are using your mobile connection (via a "hotspot" created on your Android device), then note that cellular upload speeds are often much lower than download speeds.
  • Your cellular provider may deliberately be throttling your data upload speeds.
  • Your speed may also be affected by the extra "hop" -- between your computer and the Android device.
  • On your/Ubuntu One's side, all you can do is check that you have not set Ubuntu One to itself limit upload speed:

This may also be partly due to varying signal strength on the cellular network. If you have exceptionally strong signal strength, you will get smooth connectivity, if you get widely-varying signal strength (high -> low -> medium -> low -> none -> low ...), it'll increase and decrease your connectivity crazily (and when you see 'none', well, you can guess what's there :P) –  Thomas W.
