AAsk a local member of staff to change the frequency of the microwave and see if the disconnections stop

BAsk a local member of staff to take some pictures of the microwave, including some close-ups of the door seal so that you can assess it

CAccess the microwave remotely and run a diagnostic check

DPlace one of the London APs into spectrum analyzer mode and monitor the situation over lunch time

Show Suggested Answer

Suggested Answer: D

The best way to test the theory of microwave interference from the New York office is to use a remote spectrum analyzer. By placing one of the London APs into spectrum analyzer mode, you can capture and analyze the RF spectrum in the London office over lunch time. You can then look for any signs of microwave interference, such as high duty cycle, high amplitude, or frequency hopping on the 2.4 GHz band. This method does not require any physical access to the microwave or any changes to its frequency.Reference:[Wireless Analysis Professional Study Guide], Chapter 3: Spectrum Analysis, page 64

I think we should go with option D and use the spectrum analyzer to monitor the situation.
