[Wine] Question about Steam.

[gaijin]

I am running wine1.3, installed from the winehq repo on ubuntu 10.10. I installed steam through winetricks, nothing else. After this i told steam to start installing civ V. And for some time it just downloader with 1.4mb/sec. then suddenly everything stopped... and all i could squeeze out of my connection was 150kb/sek.

Is there anything in wine1.3, or perhaps steam running under wine1.3 that makes my connections slow?
