What consideration could one make if a deployed network has good 2.4 GHz coverage with lackluster 5 GHz coverage?

When faced with a situation where a network exhibits strong 2.4 GHz coverage but inadequate 5 GHz coverage, a sensible approach is to reduce the transmit power in the 2.4 GHz band. This strategy is effective because it can help balance the signal strength between the two bands. By decreasing the power on the 2.4 GHz frequency, you can reduce the interference and contention for resources from clients that might otherwise connect to it. This can encourage devices that support both bands to connect more frequently to the 5 GHz network, where performance is typically better due to less congestion and higher available bandwidth.

In mixed-environment networks, it is essential to encourage devices to leverage the capabilities of the 5 GHz band, especially in areas where it is underutilized. Balancing the coverage effectively can lead to a healthier distribution of devices across the two bands, optimizing overall network performance.

The other options, while they may seem plausible at a glance, do not address the fundamental issue of unbalanced coverage effectively or may lead to other complications within the network.
