Correct answer: allocating nonoverlapping channels to access points that are in close physical proximity to one another.
Why this is the answer
Allocating nonoverlapping channels (1, 6, and 11 for 2.4 GHz) to nearby access points is crucial to minimize co-channel interference and maximize wireless network performance. When APs use the same channel in close proximity, their signals interfere, leading to reduced throughput and increased retransmissions. Disabling TCP is incorrect; TCP is a transport layer protocol essential for reliable data transfer and has no role in AP signal negotiation. Configuring a maximum of 5 Mbps artificially limits performance and is not a best practice. Setting the maximum data rate to 54 Mbps is relevant for 802.11g, not 802.11b, which has a maximum theoretical rate of 11 Mbps.
