Windows 10: Wifi cross symbol and unable to connect

Hello,I’m having a problems on my windows 10 computer. I changed my wifi security because I didn’t want it to say weak security everytime I open my computer, so I changed it to wpa2 to wpa3. All my devices are able to connect to the new network but my computer gives a cross mark next to the wifi symbol and says unable to connect and my wifi’s are at the bottom of the available ones. What is the reason of this and how can I solve this problem.Thanks in advance.

Unable to connect to WiFi on Windows 10.

Thank you for replying.

• 
  What is the make and model of the computer? HP
  
• 
  Did you see a red cross on the Internet connection near the Action center? Yes, there is a red cross at the lower right corner when I am unable to connect.
  
• 
  Is the WI FI symbol visible for you in action center or does the WIFI detects nearby connections? There is no wifi visible and no nearby connections detected. Everything will be fine and then when my computer updates -- I have no connection.
  I'll contact the lifetime it support group that came with the laptop when it happens. They fix it and I'm good to go until my computer updates again -- then no wifi. It's been doing this since I've updated to Windows 10 (a few months ago).

  Did you install any third party security application? I have not installed a third party security application.
  

 

RPi2 from Windows cross compilation Error "The test for linking against libxcb failed!"

Error in Cross Compilation, I am using Qt5.0, Windows10, Raspberry Pi 2.
I was following this tutorial and the process failed at step 16 and tried with its suggestion but cannot find a solution.

Error prompted after step 16 is:

Running configuration tests...
The test for linking against libxcb failed!
Use of pkg-config is not enabled, maybe you want to pass -force-pkg-config?
You might need to install dependency packages for libxcb.
See src/plugins/platforms/xcb/README.

and when I printed log in file as tutorial suggested, there are some errors mentioned like:

• cc1plus.exe: error: unrecognized command line option '-fuse-ld=gold'
  
• error "Symbolic function binding on this architecture may be broken, disabling it (see QTBUG-36129)."
  
• etc.
  

I tried but still find no solution.

 

Intel Dual Band Wireless-AC 7260 constantly drops connection

Hey guys,

first of all, thank you for reading my post. I got a massive problem with my Intel AC 7260 Wireless Adapter in my Alienware Area 51 R2.

For some reason, after nearly 3 years of constant performance and no hardware problems at all, the WiFi card of my Area 51 keeps losing Internet Connection.

The strange part is, that the connection to my router is still intact, but the Internet access gets crossed out red. I also have a notebook, an iMac and an iPhone connected in the same network and every device works just fine.

To proof furthermore that my router works just fine, I tested LAN connection on the Area 51 and there are no connections drops at all.

Back to WiFi Connection: I searched in some forums and there are some people who seem to have the same problem like me. For example: Alienware Forum - Killer wifi keeps losing internet connection

What I already tried was:

• installed latest driver from KillerNetworking (v.1.6.2149) x64

• installed latest driver from Intel 20.70.0.4 for AC 7260

• deactivated and activated Wifi Card in device manager

• deactivated IPv6 (altough it worked 3 years with IPv6 settings on)

• Power Management -> disabled "Allow computer to turn off this device to save power"

To make it as understandable as possible, I'll try to list a scheme of the problem:

1. WiFi Connection is "stable"

2. Suddenly the current application stucks because the PC has no connection to the Internet. After 10 secs, the WiFi symbol gets crossed out. Windows displays that I'm still connected to the router, but there is no Internet connection. (every other device is still connected and has internet connection though)

3. For 1 sec, the crossed out WiFi symbol changes to a crossed out Ethernet connection Symbol (like I had a LAN cable connected, with connection to the router, but not Internet connection)

4. And 5 secs later, the WiFi symbol pops up again and the Internet connection is back again.

5. Repeat multiple times a day



I can confirm that the connection drops are not coming more frequently when the download/upload-traffic is high. The connection drops in an idle state on the desktop of Windows as well.

Do you have any ideas? Do you think it's a hardware defect?

Keep up the good work!

Best regards from Germany,

Felix
