Pico W oddity.

You know those days when everything seems to be like a crack in the matrix.
The power went out for 6 hours.
Everything came back up, but two hours later a broken RJ45 fell out of the router, and the next day a PICO W suddenly stopped wifi-ing.
I reinstalled code and it still wouldn't work, then I reinstalled code again and now it does???

     “I know that most men, including those at ease with problems of the greatest complexity, can seldom accept even the simplest and most obvious truth if it be such as would oblige them to admit the falsity of conclusions which they have delighted in explaining to colleagues, which they have proudly taught to others, and which they have woven, thread by thread, into the fabric of their lives.”
