I have a mid-09 13" MBP. I just bought a display (dell U2311H), wireless apple kb and magic trackpad, with the intention to use just the external display and kb/trackpad, and stow my MBP away to save some space. Everything works fine when my MBP's lid is open. But once it is closed (or nearly closed), Wi Fi disconnects. Does anyone know how to fix this? I don't think it has anything to do with my wireless router, but more to do with some MBP setting. Thks!
