Question

A driver report shows a permitting-office PC advertises 40 MHz channel-width capability. How should the technician use that information?

Accepted Answer

Use the actual advertised client channel-width capability when troubleshooting or explaining negotiated widths. — Believe the driver's width number the way you believe the speed rating on a tire. If it says 40 MHz capable, do not pretend it is 160 MHz—and remember the AP still has the final say on the BSS width. Facts beat folklore in the ticket notes.

Answer

Invent 160 MHz operation for the PC because wider is always better in every BSS.

Answer

Ignore the driver and set client expectations using only the guest captive-portal logo colors.

Answer

Assume the PC can force every AP in the building to 40 MHz regardless of the design document.
