I ran one from here but I'm not sure how accurate it was. It said I had about 130 Kbps upload and 300 Kbps download capacity (vista laptop). Ran it again on SuSe desktop and got 300 download, 360 upload. Ran the same test while actually downloading something (Vista laptop) and it read about 20 download and 100 upload. The download failed, so the answer is yes, there are problems connecting (probably with everything).

I am able to download some things (sometimes) - earlier I downloaded a video (not quickly).
