+===== WiFi + “jerky typing” fix for low power wifi cards!!!! =====
+Run <code>ip addr</code> to find the wlan card, mine is wlp2s0.
+Test if this is the problem first.
+<code>
+iw dev wlan0 get power_save
+</code>
+if its on, it will report:
+<code>
+Power save: on
+</code>
+Turn off power save via:
+<code>
+sudo iw dev wlan0 set power_save off
+</code>
+If that works, make it permanent via (also note this isn't the "right" way, just the fastest way)
+<code>
+vi /etc/systemd/system/wifi-powersave-off.service
+</code>
+Add the following snippet
+<code>
+[Unit]
+Description=Disable WiFi Power Save
+After=network.target
+[Service]
+Type=oneshot
+ExecStart=/usr/sbin/iw dev wlp2s0 set power_save off
+[Install]
+WantedBy=multi-user.target
+</code>
+Make it permanent
+<code>
+sudo systemctl daemon-reexec
+sudo systemctl enable wifi-powersave-off
+sudo systemctl start wifi-powersave-off
