You are troubleshooting a client issue on a Windows laptop. The laptop can see and connect to 2.4 GHz APs, but is does not even see 5 GHz APs. While evaluating the issue, you determine that this problem is happening for all of the laptops of this model in the organization. Several other tablets connect on channel
48 and channel 52 in the same work areas. What is the likely problem?
The issue is likely with the client drivers, which should be upgraded. Given that the problem is occurring consistently across all laptops of the same model within the organization, it suggests a systemic issue rather than one limited to individual hardware components such as antennas. Additionally, the fact that other devices, such as tablets, can connect to the 5 GHz channels in the same work areas further supports the likelihood that the problem lies with the laptop drivers rather than the access points or antenna gain.
I think the low gain of the antennas could be the problem (option B). I would not asume a drivers' problem due to there is not so much information about the operating system used in the laptops, neither their upgrading configuration.
Usually Tablet has less sensivility than Laptos so I think the gain of the antenna is not the problem
Correct answer: D. The client drivers are faulty and should be upgraded.
B is the answer. While D may also be a possible answer, it is unlikely that all the Laptops of that model will at the same time all have faulty drivers. So B is the only realistic answer.
