Since downloading the 10.5.1 update I can no longer see other wifi networks with my Macbook. I have no trouble seeing them with my other computers but my Macbook cant see anything but my network. Last week I was at another location looking for connections and for a split second I saw the networks but before I could join one they all disappeared. I have tried starting and stopping Airport same result. Restarting does nothing either.
Any ideas?
