Used a friend's laptop today, and it achieved much higher bitrate than my mini. It also was a b/g compatible wifi card. I also noticed that the speed is low enough to make youtube videos lag (not enough buffer). I don't know if this is related to the mini or if it is a problem with mine ? I tried to measure from the web, and I get ~400 Kb/s, when both my iMac and iPhone achieve >2 Mb/s.
Now if every mini is this way, I'll deal with it, but if it's a problem with mine, I'd like to fix it. Any ideas ?
This issue aside, this is a great machine, and I thank you once again for making this possible !
