Windows 10 - Extremely slow WIFI

I am having a very frustrating time with Windows 10 Home 10.0.14393 Build 14393.

I cannot get my WiFi download speed up. Here is what I've tried so far:

I updated all my drivers.
I do not have an anti-virus running.
I disabled Windows Firewall
I made sure Windows was not updating. I also stopped Windows from updating programs automatically.
I re-installed Windows 10.
I ran the Network troubleshooter which said "Troubleshooter could not identify the problem."
I updated the firmware for my router.
I tried making several adjustments to my router.
I tried netshwinsock reset catalog
I tried netsh int ipv4 reset reset.log
I tried netsh int ipv6 reset reset.log
Rebooted several times. I turned my internet connection on and off via the keyboard.
I tried inetcpl.cpl and unclicked all the boxes in the LAN section. 
Tried Network Troubleshooting and Windows Network Diagnostics but neither could "identify the problem"
I should be getting 50/50. I am getting 4/45.
Here is my ipconfig:

C:\WINDOWS\system32>ipconfig

I know that it is windows because I can connect my ethernet cable to the modem and get over 50mps.. Additionally, this slow WiFi problem is on 2 laptops both running Windows 10 Home.


Can ANYONE offer some help? Please.

Hi Joanne,

It seems that the slow download speed only happens on your wireless devices. Since you've basically performed almost all necessary troubleshooting on both laptops, we would like to ask a few questions to help us further isolate this issue.

  • How far is your computer from the router?
  • What's the make and model of your router? Is it a single-band or dual-band?
  • Are there other devices connected to the WiFi network?


In the meantime, we suggest that you change or specify the channel of your wireless network. If you have access to your router, set it to either Channel 1, 6, or 11, then change the Channel Width to 20 MHz only. Once saved, try checking the download speed again.

Update us on how it goes.

Regards.

I made a mistake, the other laptop is fine.

I am about 2 feet from the router.

I have an Actiontec router, yes it is dual band.

I've already tried changing the channel on the router.

I also connect with my phone which gets speeds about 40.

The only problem is my laptop.

Hi Joanne, 

There are a lot of possible causes for this issue to occurred. And since resetting your TCP/IP did not work. We suggest that you Reconfigure your TCP/IP and check if there's any changes. To do this, follow these steps:  

  1. Run Command Prompt as Administrator.  

  2. Run these following commands:  

    • netsh int tcp set heuristics disabled  

    • netsh int tcp set global autotuninglevel=disabled  

    • netsh int tcp set global rss=enabled  

Let us know how it goes. 

Regards.

Hello,

Thank you for your reply. I did as you said and tested my speed but no improvement. I re-booted but still no improvement.

I've had this laptop less than a month. Is there anything left to try? This is bizarre.

  • Was this laptop working before on this same router, or is this the first time you are using it?
  • Have you tried connecting the laptop to the 5GHz band?
  • What is the brand and model of the wireless adpater? And the current driver version?
  • Have you encountered this problem after the upgrade to that build version?

For isolation, either try:

  • Connecting the laptop to a different WiFi network
  • Or use a different wireless adapter

I bought the laptop 3 weeks ago. I upgraded from 25 to 50 mps about a week and a half ago. I never tested the speed until I upgraded. 

I tried:

802.11b/g/n)  my d/l is 2.56 and u/l is 48.08    2nd laptop is d/l 24.85  u/l 24.50  cell phone  d/l 45.14  u/l 47.96

802.11b/g - my  d/l 18.07 and u/l 7.74            2nd laptop d/l 20.06  u/l 16.75      cell phone d/l 6.72   u/l 22.19

802.11n - my d/l 8.41 and u/l 31.79                 2nd laptop d/l 33.17 u/l  15.17      cell phone d/l 17.42  u/l 16.80

I have a Dualcomm Atheros QCA9377 Wiresess adaptor. The driver is the most recent, dated 8/23/16 ver 12.0.0.278. 

I have an Acer Aspire. In the product description Acer says about the adapter, "Wi-Fi featuring MU-MIMO technology (Dual-Band 2.4GHz and 5GHz)" if that helps.

I have had the same low speed before and after updating the driver.

I do not have another network to connect to, there are no unsecure networks available to me and I do not know anyone nearby who would give me access to their network.

Wouldn't I have to open the laptop to install a new wireless adaptor? If so, I may as well return the computer, no?

Hi Joanne, 

Apologies for the late response. 

Is this issue happening when you are using a different internet connection? It is also possible that the issue is due to your hardware or the device itself. Have you contacted your Internet Service Provider (ISP)? If not, kindly contact your ISP to double check the connection and pin point if either your Software or the Hardware has the issue. In the meantime, kindly perform a Clean Boot and check if there's any changes afterwards. It is also possible that the applications running in your computer's background are causing your internet connection to drop or slow down. 

Note: Reset the computer back to Normal Mode once you are done with the troubleshooting by following the section "How to reset the computer to start normally after clean boot troubleshooting" from the same article. 

Let us know how it goes. 

Regards.

I do not have another connection to test. My phone gets 45 d/l 43 u/l on this connection. A 2nd laptop in the house also gets high speed. It is just m laptop with the problem.

I spoke with Verizon and they say there is nothing wrong on their end.

I performed a clean boot but the speed was still poor. 3.95 download, 41.57 upload. 

Perhaps I should just return the computer as it is only a month old and I am thinking there is a problem with the hardware.

Joanne,

I'm inclined to agree with you that this might be a hardware issue on your laptop. But just to be sure, try bringing your laptop to Starbucks or McDonalds or other place where you can connect wirelessly. If you experience the same problem, then definitely, problem is with your laptop.

Now, your question, "what if it works with other Wifi hotspot?".  Then, we may need to look at the configuration of your router's wireless settings.

Just curious, do you know how to access your wifi router's configuration page?

I do know how to access the config for my router. I have tried changing the channel and tested speed on each band but my d/l speed is still too slow.

I am returning the laptop. I have spent so much time trying to get the speed to work already, I'm sure this is a hardware problem now.

Thank you all so much for your time and suggestions. I really appreciate the help!!

Joanne
