Selected Answer: B

Answer: B. Use a spectrum analyzer and check the 6GHz spectrum. In a standard troubleshooting methodology, after identifying a likely cause (suspected 6GHz interference), the next step is to collect evidence to confirm or rule out that cause. You would use a spectrum analyzer to observe the 6GHz band directly and verify whether there is indeed interference and on which channels. Once you have that data, you can then decide on the appropriate remediation steps (such as changing channels, etc.).
