I think A and D could be the issues. Renovations can mess with signals.

Yeah, but if it’s not enabled, it could still affect performance.

C seems less likely. BSS color mode usually helps, right?

D could be an issue as well. If the client can't use certain channels, it's bad.

B is definitely a possibility. It limits call capacity.

I lean towards B too. Low Call Admission Control can cause issues.

Agreed, A makes sense. New walls can block Wi-Fi.

Wait, the client doesn't support U-NII-2 channels? That seems unlikely.

I read that if a client doesn't support certain channels, it can cause issues, so option D could definitely be a contributing factor too.

I feel like we had a practice question about BSS color mode before, but I can't recall if it directly affects call quality. Maybe option C is relevant?

I'm not entirely sure, but I think if the Call Admission Control is too low, it could lead to poor call quality. That makes option B a possibility.

I remember we discussed how recent renovations could impact Wi-Fi coverage, so option A might be a factor here.
