A parks-department tablet advertises 80 MHz channel-width capability, but the AP BSS is set to 20 MHz per the design. What happens to the link width?
Select an answer to reveal the explanation.
Short Explanation
Capability is the ceiling, not a remote control for the AP. If the BSS is 20 MHz, the link settles there even if the tablet could do 80 MHz in a wider BSS. Read both sides before chasing a 'slow Wi-Fi' ghost.
Full Explanation
Client channel-width capability describes the maximum widths the station can support. Actual operating width follows AP/BSS configuration and negotiation. A client advertising 80 MHz will operate at 20 MHz when the BSS is 20 MHz; it does not unilaterally widen the channel or invalidate the design document's width choice.
