On my MacBook, I lose my wireless connection rather frequently. When I go to the menu bar to change my network when I lose the connection, it seems like there are more wireless networks available from when I first connected. It seems as though I lose the connection when more or less wireless networks become available. How can I solve this? In fact, as I type this, I just lost the connection and have to reconnect. It's not a big deal, but it's frustrating.
