Question

Internet Access is Good. Internet Connection very weak on laptop.

Steve Travia 0

This is not a Internet issue. I can access internet on another laptop and mobile phone, but not on MS Notebook Service Pro. It happened in the past 5days. I'm on Windows 11 and was working fine up until the other day.

I tried every trouble shooting and can not fix. I can even run updates cause I can't connect to internet. Please help.

Answer 1

Since other devices connect normally, the problem is likely on the laptop or its connection path rather than the internet service.

Try these steps in order:

Run the Windows network troubleshooter.
- On Windows 11, select Start and type settings.
- Go to Settings > System > Troubleshoot > Other troubleshooters.
- Run Network Adapter and follow the prompts.
Check whether the network works on another device.
- Since another laptop and phone already work, that points to the Windows 11 laptop as the likely source of the issue.
Restart the modem and Wi-Fi router.
- This creates a new connection to the ISP.
- Everyone on the Wi-Fi network will be temporarily disconnected.
If using Ethernet, check the cable and port.
- Make sure the cable is firmly connected on both the router and the PC.
- Make sure it is connected to the correct Ethernet port on the router, not the modem/router internet port.
- If possible, try a different Ethernet cable.
If Ethernet is failing, try Wi-Fi instead.
- This helps confirm whether the issue is only with the wired connection.
Reset the network stack from an elevated Command Prompt.
- Search for Command Prompt.
- Select Run as administrator.
- Run these commands in this order:
  - netsh winsock reset
  - netsh int ip reset
  - ipconfig /release
  - ipconfig /renew
  - ipconfig /flushdns
Use Network reset as the last step.
- Warning: this removes and reinstalls network adapters and resets their settings to default.
- VPN clients, Hyper-V virtual switches, or other networking software might need to be reinstalled or set up again.
- Known networks may be changed to Public profile after the reset.
- On Windows 11, go to Start > Settings > Network & internet > Advanced network settings > Network reset.
- Select Reset now > Yes.
- Wait for the PC to restart, then test the connection again.

If the laptop still shows a very weak connection after these steps while other devices remain normal, testing the same network with another device in the same location helps confirm the laptop is the source of the problem.

Hi, I'm Bernard. I'm happy to help!

Based on your inputs, this issue occurs when there is a miscalibration in the network or internet configuration. To sort out the issue, kindly follow the steps below:

Method 1. Roll back Network driver:

-Press the Windows key + X

-Go to Device Manager

-Expand the Network Adapters

-Look for the Wireless driver that was installed

-Right-click and click Update Driver

-Select Browse my computer for drivers

-Click Let me pick from a list of available drivers on my computer

-Choose an old driver or another driver name, then select it and hit next until it installs.

-Restart the PC and check.

If the issue persists, run the following command in Terminal (Admin). Follow the steps below to do so.

These sets of commands will reset the internet connection and recalibrate the internet settings you have.

Press Windows Key + X.

Click on the Terminal (Admin) or Windows Powershell (admin)

Type the following commands, and hit Enter after each command:

netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

If the same issue follows the methods below:

Do a clean boot:

A “clean boot” starts Windows with a minimal set of drivers and startup programs so that you can determine whether a background program is interfering with your game or program.

In the search box on the taskbar, type msconfig and select System Configuration from the results.
On the Services tab of System Configuration, select Hide all Microsoft services, and then select Disable all.
On the Startup tab of System Configuration, select Open Task Manager.
Under Startup in Task Manager, for each startup item, select the item and then select Disable.
Close Task Manager.
On the Startup tab of System Configuration, select OK. When you restart the computer, it's in a clean boot environment.

Hi Steve Travia.

Are the laptop and the router in the same room, or are they in different rooms or on different floors of the house? Do you connect directly to the router's Wi-Fi network, or via a Wi-Fi repeater or range extender?

Right-click the Start button > Device Manager, expand "Network adapters," and post a screenshot.

Yes. I tried all locations in my house and in front of my modem/router. Same problem

What is the exact model of your Wi-Fi adapter? Otherwise, go to Device Manager, expand "Network adapters," and post a screenshot.

Hi Steve Travia.

Temporarily set up a 5 GHz hotspot on your smartphone, then connect your computer to the phone's hotspot and check if the Wi-Fi connection is still slow or if it seems normal.

If the Wi-Fi connection to the phone's hotspot is normal, the issue lies with your router or home network configuration.

Hi, thank you for the update. In this case, I recommend downloading and installing the Wi-Fi driver from your manufacturer's website and/or updating the BIOS with the help of the PC manufacturer.

If the issue persists, and since it only started happening 5 days ago, I suggest performing a system restore to a point when the PC was working properly. To do that, kindly follow the steps below:
