hi all, is anyone else having problems with connecting to wifi networks? my Macbook Pro C2D with airport N enabled, sometimes cant connect to internet open wireless networks, while guys with windows (either Visa or XP) do it all the time. I'm also having problems with my home internet. it just cant get a permanent connection while if I use my Acer with windows XP, it connects with no problems. Is there anything I can do to fix this?
