A warehouse puts every access point on 2.4 GHz only, and capable laptops and the old scanners all share it. Airtime is exhausted. What change helps the laptops without taking the scanners off the air?
Select an answer to reveal the explanation.
Short Explanation
Everyone is crowded onto the band that only has a few clean channels. Let your laptops use 5 GHz, where there is more room, and leave 2.4 GHz for the scanners that cannot follow. More radios on the same channel just lengthen the line.
Full Explanation
The 2.4 GHz band has only a small set of non-overlapping channels, so a warehouse that puts every access point there exhausts the airtime. Laptops that can use 5 GHz should move to a 5 GHz WLAN, where more non-overlapping channels exist, and the scanners stay on 2.4 GHz. Adding access points on the same 2.4 GHz channel adds contenders, not new airtime. A 2.4 GHz-only scanner cannot retune to 5 GHz. An 80 MHz width is not how 2.4 GHz yields three clean channels. That band does not have an 80 MHz plan that creates three non-overlapping channels. Putting every access point on 2.4 GHz guarantees contention because that band has few non-overlapping channels. Clients that can use 5 GHz should not all be stuck on 2.4. Check one live client after the change and leave the rest of the floor alone until that client matches the result you expected. Exam caveat: the laptops only benefit if they actually join the 5 GHz WLAN. A policy that keeps steering them back to 2.4 GHz undoes the split. Operational check: put a test laptop on 5 GHz, leave a scanner on 2.4 GHz, and confirm the laptop's airtime is no longer waiting on the scanner channel.
