HP 501 Bridge Disassociates from Wifi When Not In Use

Hello,

I have an HP 501 bridge attached to a vitals monitor. When the monitor is put into standby mode between patients or overnight, the bridge disassociates from the wifi. I can see when it happens in Cisco Prime.

I have the config for this bridge. My question is: what is the setting I need to adjust to tell the bridge not to go to sleep/disassociate?

Thanks in advance,
Anthony
