No. 63/592,289, filed on 23 at 10 at 2023, each of which is assigned to the assignee of the present application and is hereby expressly incorporated by reference in its entirety as if fully set forth herein below for all applicable purposes. Technical Field The present disclosure relates generally to wireless communications, and more particularly to aspects related to selecting a bandwidth configuration for a network supporting multiple channels to contend for access to a wireless medium. Description of related Art A Wireless Local Area Network (WLAN) may be formed of one or more wireless Access Points (APs) that provide a shared wireless communication medium for use by a plurality of client devices, also referred to as wireless Stations (STAs). The basic building block of WLANs conforming to the Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards is the Basic Service Set (BSS) managed by an AP. Each BSS is identified by a Basic Service Set Identifier (BSSID) advertised by the AP. The AP periodically broadcasts beacon frames to enable any STA within wireless range of the AP to establish or maintain a communication link with the WLAN. In some WLAN scenarios, devices share access to a wireless medium. In such scenarios, contention-based channel access is a mechanism for sharing wireless media. This mechanism allows multiple devices to access the same wireless channel without a centralized coordinator, making it suitable for use in a scenario with a variable number of devices. For example, a device that wants to send data first listens to the wireless channel. This process is called carrier sensing, where the device first checks whether the channel is idle or busy. If the channel is sensed as busy, indicating that another device is currently transmitting, the carrier sensing device will wait for an idle period before attempting to transmit.
