i don't know why everyone complains about the wifi reception on powerbooks... we just updated from 802.11b to 802.11g in our house. with the hub in the basement, i can be in my bedroom (two floors up and across the house) and always have a full signal. something i would like to mention though is that upon making the upgrade from 'b' to 'g', there has been a phenomenal increase in speed. i would advise anyone that uses wireless to seriously consider an upgrade if you're not already there. 😎
