MacBook Wireless Problem Plague.
There is something amiss with the MacBook wireless adapter - I have read on many another a place that other folk are experiencing very much so the same problems as me in that when either resuming from sleep or just intermittently the wireless connection drops sometimes not to be recovered for an hour or so - the diagnosis for many a folk was to adjust router settings but to have to go through all that, especially when you don't own the WiFi network is just plain crazy - perhaps a Firmware update will do the trick but as of now, there is DEFINATELY a problem with all MacBook wireless adapters - in short, being unreliable.
