So, I call Comcast to come out today because my internet is going slow. 55k instead of the 4MB I'm paying out the ass for. Long story short, here are the results of our speed tests today.. PowerBook on internet connected AirPort Express = 1900k PC on AirPort Express (with a wireless B card, mind you) = 3200k PowerBook wired directly to modem = 1900k PC wired directly to modem (same ethernet cable) = 4200k AirPort Express slows things down, then the PowerBook makes things worse, yet the PC (XP SP2) seems like it's doing everything it can to go as fast as possible. Can anyone offer any insight to this? I'd really like my PowerBook to be as fast as it can online... Thanks. EDIT: BTW, the testing was done at Speakeasy.net using the same server each time. Results are similar at pcpitstop.com (lower scores but same pattern of results).
