The keywords for my issue are too common among other issues, so, I couldn't find anything that could answer me: why will it take around 30+ seconds for any of my browsers to open a page? happens even with google.com... with both Firefox and Chromium. This does not happen while I use Windows, from exactly the same point at my house (I've got enough wi-fi signal here for sure).

Also, the standard torrent client won't hit the max download speed... I can hit 1 Mb/s with utorrent on Windows, and can't go over 300 kbps here. I tried changing the program settings, no results.

Please help me. I REALLY don't wanna go back to Windows.

Thanks in advance, I admire this community, and I'm sorry that I couldn't find something that could help me. I already solved a lot of issues without asking, but couldn't do it this time.
