I recently had to re-setup my wireless network and now all of a sudden whenever my Macbook goes to sleep it disconnects from the network. Not only that but it pops up a message saying none of the preferred networks can be found. Granted I have my network set to invisible, but I thought once it had the name and password as a preferred network that didn't matter? Any ideas what's going on? The only thing I changed on my network setup was the password as far as I can recall.
I'm running a 2.16GHz C2D with 10.4.11 and using a D-Link DIR-655 Xtreme N Gigabit Router.
