Windows 10: WiFi “Cant connect to this network”

My wife’s computer was working fine a couple days ago but now we cannot connect to any WiFi signals in the house. I have reset the networks, reset the computer as Microsoft told me and connected to an Ethernet cable to update the laptop.

It’s now on version 2004 and the drivers for the networks are still not showing up. I’m not sure what to do now after this.

Do I need to run it in admin to fix the issue?

Thank you for the help in advance. I’ll check back in the morning

How to connect to an existing wifi network?

As you suggested, I tried disabling the ethernet adapter and that caused wi-fi to connect, so the desktop wifi does work. Also, I accessed the router and changed the wireless network name (to wfCHS). Thanks!

However many problems are still unresolved:

My laptop behaves just as I want it to. Assuming the router has wifi turned on and the laptop has an ethernet connection, connection to the internet is by ethernet (no private network name), and the wi-fi connection is to my private network "wfCHS", but with no connection to the internet. (If I disconnect the ethernet cable, then wfCHS becomes connected to the internet and stays that way even if I reconnect the cable.) A directory listing shows both laptop and desktop under "Network". Great!

Things are rather different with the desktop. With Ethernet disabled, the desktop shows a wi-fi connection to the internet. Under Settings > Status it's called "wfCHS" but under Network Connections it's called wfCHS2. If I then re-enable the ethernet connection, the wifi connection stays enabled for a minute or two, then disconnects. Further, the ethernet connection is given the name wfCHS2 under both Status and Network Connections.

Why does the desktop give an (unwanted) name to the ethernet connection while the laptop doesn't?

Why does the desktop disconnect its wi-fi connection a minute or so after the ethernet connection is enabled, while the laptop doesn't?

Why does the desktop give two different names to the wifi connection, depending on whether it's viewed under Status or Network Connections, while the laptop doesn't?

Why does the laptop show the desktop under Network, while the desktop shows only itself?

Things are so convoluted that I'd be happy to start over. I've had the desktop "forget" the wi-fi connection as you suggested, then re-established it, but this hasn't helped. Can the ethernet connection also be "forgotten"?

Really appreciate the help you've given so far!

Hi
Myamara,

It is possible that your drivers are outdated or the connection itself has the issue. We suggest that you perform
these methods of troubleshooting

  this command:
  
  • 
    netsh int ip reset
    and hit
    Enter.
    

Exit
Command Prompt
and
monitor your WiFi connection.

Method 2: Disable auto turn-off of WiFi device.

Go to
Network and Sharing Center. At the
right pane, click
Change adapter settings.
Right-click
on your
connection name(WiFi name)
and go to
Properties.Click
the
"Configure..."
button and go to
Power Management
tab.Uncheck/disable
the
radio button
for
"Allow this device to turn off this device to save power". And then,
Restart the PC(Important).

Method 3: Reconfigure TCP/IP

To do this, follow these steps:

• 
  Run
  Command Prompt
  as
  Administrator.
  
• 
  Run
  these following commands:
  
  • 
    netsh int tcp set heuristics
    disabled
    
  • 
    netsh int tcp
    set global autotuninglevel=disabled
    
  • 
    netsh int tcp set global
    rss=enabled
    

Update us on how it goes.

Regards.

 

Windows 10 cant connect to network

Welcome to Ten Forums allekup,

This sounds like it's more to do with the settings on the routers in the two different houses than on the PC....

If you have been looking just at the PC settings, then it's time to compare how the two different routers are set up.

In the house where you can connect without problems, when you click the WiFi icon on the taskbar do you see the 2.4GHz and 5GHz networks listed separately? A router can be configured to either broadcast a different SSID (name) for each, or to use the same SSID for both. If you see two names the router is using separate SSIDs for each.

In the other house where "...the 5ghz network doesnt even show up..." the router may have 5GHz turned off, or more likely may be using the same SSID for both networks. Once connected, you can tell if your connection is using 2.4GHz or 5GHz by looking in Settings > Network & Internet > WiFi > Hardware properties.





Does the WiFi in each house use the same SSID name? If so, that may explain the ...95% of the time it says “cant connect to this network” . You may be trying to connect in house 2 with the password from house 1. Give each router a unique name to solve this.


Another possibility is interference from nearby WiFi routers using the same channel as yours. You can see all the WiFi signals and their signal strengths with WiFiInfoView from Nirsoft. If other WiFi on the same channel is the problem, this will help you pick a new channel for your router with less interference.
