Thanks,

Considering the situation maybe this is a good sign. Perhaps those two resistors are broken. Can you measure them? They should be both 10K.

I went ahead and checked all the resistors on the board. I found 3 bad ones. R8 & R15 are measuring around 1K instead of 10K and R16 is measuring 5.5K instead of 10k. 

I'm not sure what I did to cause this, but obviously the damage has been done. I will replace them and report back.

Hold on. That is quite strange.
What is the number imprinted on R8, R15? All should be 103. Can you post a picture of your board?
Measuring R16 in the circuit should give a value of 5.5K or 5.6K, so it is correct.
I checked all the Pro2 PLUS boards I still have from the same batch and all have the correct resistors. Even if those resistor are wrongly 1K, they don't cause the damage of the WiFi module.

You may haven't did anything wrong, it never happened before but there is also the possibility that the WiFi module was faulty from factory.
We will solve the problem, please check your inbox, I sent you a PM.

R8 and R15 are both imprinted with 103. See pictures below.
