MacBook Pro Early 2011 Wifi (Airport Card) not connecting after sleep!

Question

hi, i have a MacBook Pro Early 2011, and it has been fine since purchase, up untill about a week ago.I had Snow Leapord and upgraded via Mac Store to Lion shortly after its release and have had no problems up until now.i know other users have complained of delays and slow booting times but mine has been fine, never crashed or anything of the sort.i am a moderate user and have been looking into the issue and seem Apple themsevles are yet to address the issue. (typical)Some have suggested sending it off for repair, i have the additional warrenty on mine so that will be fine but i will then be without it for weeks which i cannot afford to miss at the minute, and i do not think this is nessesary as it is only intermittant, and only happens when the laptop is in sleep state for an extended period of time, therefore suggesting more of a software problem.i have tried deleting the system configuration preferences as others have suggested and it seemed to work for but now after about 4 days the problem has returned and i have to reboot in order to activate the airport card again.when i check on system information it says that the card is disconnected but then reboot and it says its connected and fine?

Try the basics first:   Change your router channel number.  Most times this works &amp; is all you have to do.Disconnect &amp; reconnect your modem.  unplug it for about 10 seconds.  Plug it back in.  Do the same for Apple’s routers.  Wait for everything to reboot.System Preferences&gt;NetworkClick the Assist Me button.In the next window that pops up, click the Diagnostic button &amp; do the necessary.
