wow, wireless go BOOM!

[Kim Quirk]

Elijah,
Thanks for this information. It would be great if you can start a bug with
all this info and then we can follow the suggested steps and results.

Ricardo - can you add suggested tests for Elijah since this is an area you
have spent a lot of your time recently :-)

Thanks,
Kim
