I didn't try a "cold reboot" that did not involve the removal of battery and power supply, so maybe it would work.
Honestly I am still perplexed (given modern hardware and software), as to why/how: 1) Hibernate and un-hibernate, regardless of what happens in between with the wireless card, could somehow result in it stopping working 2) Rebooting (warm), regardless of how the wireless card is messed up in my situation does not fix the problem 3) Cold rebooting and warm rebooting are different in any way whatsoever (all of the above involve zero changes on the hard disk during the time when the OS is not running) Is this behavior some sort of "feature" with unintuitive results, or is it a bug? And what is the buggy component, exactly? It seems like something that would happen with early 1990's technology. Also, are you saying that there is some sort of known problem that results in you having to "recover the wireless" via a cold-reboot? What is this problem and is it similar to my situation?
