How to Fix: Slow WiFi Internet Connection on Windows 10 Laptop

So, you have a slow WiFi internet connection on your Windows 10 laptop! Guess what? I had exactly the same issue!

The good thing is that I don’t have the issue anymore and I would like to share with what solved the problem in my case.

Note that each case might be different, and there is always the possibility where you might have a faulty hardware component, in this case, a faulty wireless network card or router.

This article, assumes that your hardware works properly.


What I have tried but did not work

I have tried several things in order to overcome the issue but unfortunately all failed, or maybe helped a bit, but not to an extend that solved the problem.

So, here’s what I have tried first:

  • I have rollbacked my wireless network adapter’s drivers to an earlier version
  • I have installed the latest drivers for my network adapter
  • Multiple restarts of my laptop and router
  • Made sure that my laptop was not away from the wireless router
  • Made sure that no other devices on my network were consuming all the bandwidth
  • Reconfigured my TCP/IP
    • netsh int tcp set heuristics disabled
    • netsh int tcp set global autotuninglevel=disabled
    • netsh int tcp set global rss=enabled
  • Disabled the the Peer to Peer Update Process on my computer
  • Disabled the Windows Auto-Tuning feature


What finally solved the problem with the WiFi

So, even though I had tried all the above, still, the internet connection through WiFi on my Windows 10 laptop was still slow.

I was desperate!

Then it occurred to me: I’m experiencing a slow WiFi internet connection on a laptop

It is well known, that laptops, in order to save energy, have by default, energy-saving power plans in Windows so that the laptop can work on battery longer. So, I directly opened my Windows 10 power options (Control Panel\All Control Panel Items\Power Options\Edit Plan Settings – “Change advanced power settings“) and started checking. Eventually, I have ended up in “Wireless Adapter Settings” and then “Power Saving Mode“. There, I have noticed, that the “On battery” setting was not “Maximum Performance”.

So what finally solved the slow wifi internet connection on my laptop was to set both “On battery” and “Plugged in” settings for the “Power Saving Mode” for my “Wireless Adapter Settings” in Power options to “Maximum Performance”:
