Recently one of our writers at Howtechwork found herself in this same condition, a week ago. But here are the good news, and the news is that she got it fixed by our administrator.

Before then, she has tried many ways of thinking she could be able to troubleshoot the problem.

Unfortunately, she couldn’t fix it until she summons one of our technical administrators to solve the slow WiFi internet connection.

However, we will tell you all the solutions she has tried by herself that failed as well as the solution that fixes the slow WiFi internet connection.

NB: you have to be aware that each case might be different. This means the cause of my slow internet may be different from your own.

Sometimes the problem might be from a faulty hardware component. It may be a faulty wireless network card or router.

In such a case, the fix or solution might be different. So this blog post assumes that you have a working hardware component.

Though maybe the solution that she has been trying on her own also contributes to the admin success.

Below is the list of solutions that she has tried that failed.

  1. Restarting the computer as well as the WiFi router many times.
  2. Rolling back the wireless network adapter’s driver to an earlier version.
  3. Ensure that no other devices on my network were consuming all the bandwidth.
  4. Move the laptop closer to the wireless router, to be sure distance is not the cause of slow internet connection.
  5. Disabled the Peer to Peer Update Process on the computer.
  6. Updated the network driver adapter to the latest version.
  7. Disabled Computer Windows Auto-Tuning feature.
  8. Reconfigured the TCP/IP configuration using the below commands.
  9. netsh int tcp set heuristics disabled.
  10. netsh int tcp set global autotuninglevel=disabled.
  11. netsh int tcp set global rss=enabled.

After trying the above-listed solutions, none was able to fix the problem. Despite all the effort put in, it all failed.

Finally, the computer was brought to one of our system admin. And the solution he applied that fixed the slow WiFi internet connection is ridiculously simple.


A solution that finally solved the Slow wifi problem

For the fact that she has tried all the solutions mentioned above and failed, she still did not relent. Still, the slow WiFi internet connection on the Windows 10 computer persist.

So, therefore, She decided to take the Laptop to someone who has more knowledge in ICT than herself.

When the laptop gets to the hand of one of our Technical experts at Howtechwork, the problem got solved magically.

She explained every single solution that has been applied to fix the system that all failed to the administrator.

So the admin decided to plug the PC to a power outlet and test the WiFi speed. Behold, the WiFi speed became blazing as the speed of light.

I was now wondering what could cause the laptop internet to be slow while on battery alone.

The Howtechwork system administrator now explained to me that, It is a common practice by the windows operating system for laptops, to save energy.

They put the laptop computer into energy-saving mode by default, once it is not plugged in so that the Computer can work for a long on battery.

The whole trick is just to save battery and extend its usage time.


How I fixed the slow Wifi connection

So, now that she has known the cause of her problem. She quickly opened her Windows 10 laptop and go straight to power options in Control Panel and Edit Plan Settings.

Under the “Change advanced power settings“ option, continue searching until she finally found the “Wireless Adapter Settings” then “Power Saving Mode“.

On getting there, you will notice that the “On battery” setting was not set to “Maximum Performance”.
