Intel Wireless AC-9560 Slow Internet Connection Fix

Disabling power management on the device remedied a batch of anomalous events ... perhaps it will work here.

Here's how I did it:

Create: /etc/network/if-up.d/wifi-powerman-off Enable: chmod +x /etc/network/if-up.d/wifi-powerman-off

Replace interface name (Use ifconfig to know the wifi interface name)

#!/bin/sh

IWCONFIG=/sbin/iwconfig WLAN_IFACE=<>

if [ ! -x $IWCONFIG ]; then exit 1 fi

if [ "$IFACE" = $WLAN_IFACE ]; then $IWCONFIG $IFACE power off fi
