Why Does My WIFI Drop on Battery Power?
In fact, the reason why you have no WIFI connection or WIFI is in poor performance lies in your power settings and power saving options. To get to the bottom of it, it denotes that you have set your power settings to reduce the power supply for the wireless network adapter and that you even allow your PC to turn off the device to save power. In this way, you are experiencing now the WIFI connectivity issues due to the network adapter power management on Windows 10, 8, 7.
How to Fix Windows 10 WIFI Drops on Battery Power?
In accordance with what causes severely reduced WIFI on battery on Windows 10, there is much need to change the power management settings and power saving options for the WIFI adapter and the power. What’s more, keeping the WIFI driver updated can also be a useful method.
Solution 1: Change Power Saving Mode Performance
One reason why your WIFI has a poor performance on Windows 10 lies in that you have used the WIFI hotspot with wireless Adapters or the routers that grant little support for the 802.11 power save protocol on Windows 10. You need to configure the power saving mode performance to make it work as maximum performance even if your laptop is using the battery.
Under this circumstance, you would better manage to make changes to the power saving plan, which in another sense is to turn off the 802.11 power save protocol.
1. Stroke Start > Settings > System.
2. Under Power and Sleep, click Additional power settings.
3. Choose Change plan settings. Here you choose the one according to your power plan. If your power plan is Balanced, click the one Change plan settings beside it. This holds true for Power Saver.
4. Locate Change advanced power settings.
5. In the Advanced settings window, scroll down to find out Wireless adapter settings.
6. Then expand the Power save mode and choose On battery to set it as Maximum performance. And then set Maximum performance when Plugged in as well.
7. Here if you choose to set the performance as Medium power saving, you will turn on 802.11 power save mode.
8. Hit Apply and OK to save changes.
Once you have set the wireless adapter as maximum performance when you plug a mobile PC into a power source or on battery power on Windows 10, you have also turned off the 802.11 power save mode. And in this way, wireless AP would not buffer the packets that network adapter receives which can also fix the WIFI slow connection or a poor performance issue on Windows 10.
Solution 2: Disallow Windows 10 to Turn off the Device to Save power
If you have made your laptop turn off the device to save power, it is likely that WIFI disconnects when on battery power as it tries to save power when using the laptop battery.
1. Go to Device Manager.
2. Expand Network adapters and then right click the WIFI adapter driver to open its Properties.
3. In WIFI adapter driver Properties, under Power Management, uncheck the box of Allow the computer to turn off the device to save power. If this item is grayed out on your computer, you can fix it from here.
Or you can also choose a value for the advanced power saving option.
4. Under the Advanced tab, choose one setting in Property and change Value for it.
Here you can choose power management for the properties list and change to the best-matched value for it.
5. Click OK to save changes.
Although you may have already closed the 802.11 power save mode, your WIFI on Windows 10 still drops now and then.
Now your PC won’t turn off the WIFI adapter so as to lose WIFI connection when on battery power.
Solution 3: Use High-Performance Power Plan
When you connect a PC to a WIFI but find it not smooth for the power saving mode included in Windows 10. You should have found that when you are using WIFI on battery power, this WIFI connectivity issue can also occur to your Windows 10.
Maybe it is time for you to change the poor performance to High performance.
Follow the path to complete the process: Start > Settings > System > Power and Sleep > Additional power settings > High Performance.
Then you will find your WIFI on the PC has become faster and you have successfully solved the WIFI connectivity issue on Windows 10. In most cases, laptop WIFI connection issue will be solved and WIFI icon missing is nowhere to be found as well.
