Make sure 'Wake for Ethernet network access' is checked under the Energy Saver preferences. However, I have never been able to get the MacBook Pro to wake from sleep with the cover closed. I suspect this is done for cooling purposes. I have had some success when a 2nd monitor is connected and turned on. Your mileage may vary.
With respect, iFixit, add additional puns. We love your extremely contrived attempts at humor. They simply work, never detracting from the articles. They are as welcome as caviar on toast. Please, be funny! We come here for two things, stripping and comedy. No one else does it better.
