I think it's true that it shares space with two channels, but nobody is dominating your experience!
They are spread out evenly on channels 1, 6 and 11, but maybe it’s better to pick one near the least busy channel, such as 7 or 4. Is overlapping with another channel actually worse than overlapping with the same one? I just shifted mine by one channel to the right or left, and wow—connection at the other end of my house turned into watching YouTube videos!
No way! Picking 1, 6 or 11 lets the AP detect other overlapping signals. Choosing a channel in between means it can't transmit and will try to go over top of other traffic, making it unstable. Plus, because of how the channels function, you'll be overlapping with about two-thirds of the whole spectrum.
Two close APs sharing the same frequency work by pausing briefly to check for other transmissions. Once conditions are clear, they broadcast, but they wait a short interval to see if another device is active. If both detect a collision from the same timing, they randomly select a retry time before attempting to resend. On overlapping channels, they follow the same process, ignoring other signals and rarely spotting collisions. Packets that don’t reach correctly are either discarded or retransmitted after a timeout. If APs are well separated or under light use, the network can achieve better throughput. Focusing on channels like 1, 4, 8, or 11 is often advised, as these reduce overlap. This approach works best when you manage all nearby devices—such as in offices or hotels—so everyone aligns with the same settings.
Issues arise consistently; collisions and data drops are inevitable. Random timers and slot allocation are employed to mitigate the problem, though it remains a half-duplex technology.
This feature aims to resolve issues by letting all access points coordinate their transmissions, ensuring no two APs send signals simultaneously and sharing equal time slots. This setup prevents any single AP from overwhelming the network. Currently, it only functions when every AP supports WiFi 6, which won’t benefit most home users for a while. However, it’s ideal for businesses, schools, hotels, etc. Upgrading my laptop to WiFi 6 makes sense since I might soon encounter a fully upgraded hotel room and could see a significant difference in performance.
