I have brought some games from yahoo and from real arcade and I am having problems downloading them. As for the yahoo games the downloading stops and never resume. For the real arcade games I keep getting an error stating make sure I am connected to the internet. I call real arcade and they sent me a cleaner but that didn't work. I also restore my computer back to factory use and that didn't work either.

Go here:

Speedtest.net - The Global Broadband Speed Test

do the test over, say, three days, recording the results at different times of the day.

Afterwards report back.
