Iconia W4 820 - WiFi issue (WLAN Extensibility Module has stopped)

Hi!

 

I am using my W4-820 for over 8 months and i am generally satisfied with it. My company got me Iconia 8 W for work and despite lower hardware specs it performs well and it's good for light usage.

 

However, I have issues with my W4 that are bugging me for some time now. I tried to solve it but I am running out of ideas so I seek help here.

 

Issue: I often can't connect to new WiFi hotspots.

 

Additional info:

  • OS: Windows 8.1 Update
  • Drivers: I tried from Acer Support site following versions: 1.13, 1.15, 1.16

When I want to connect to a new WiFi I use standard method -> Charms bar -> WiFi -> select network -> "Connect". However, I get "Cannot connect to the network".

 

One odd thing catched my attention:

WiFi icon

 

When trying to connect to a new WiFi network that icons changes.

 

Initially when I want to connect it's like this: A)

 

Than, while tablet is still trying to connect, it changes to the one with red cross: B)

No networks

 

And after that it changes back to the A) and says it can't connect.

 

So, after some time sniffing around Event Viewer I saw that WLAN Extensibility Module stops every time when I want to connect to WiFi network.

After Googling for a while general advice was to install drivers. So, folks, I tried this:

 

  1. Restart tablet;
  2. Reinstall WiFi drivers, restart tablet;
  3. Install older version, restart tablet;
  4. Remove old drivers, install newest drivers, restart tablet;
  5. Reinstalled Windows from recovery partition, restart tablet;
  6. Removed recovery partition, installed Windows 8.1 (downloaded from MSDN) from scratch, installed latest drivers from Acer support page, restart tablet;
  7. Tried different access points, connecting with other tablets and devices
  8. Did I mention that I tried to restart tablet?

 

I can connect to known networks and it works okay. When I wanted to manually add networks it didn't work. I also tried restarting services but it didn't help. I restarted these:

  • Windows Connection Manager
  • WLAN AutoConfig
  • WWAN AutoConfig

 

I am by no means rookie. I think I am power user so I hope I'll get that sort of help Smiley Happy

 

What else can I do?

    Attach an inSSIDer report or similar showing the devices you are trying to connect to ? Could be having cross channel interferance.

    I'm guessing you have already tried the steps here. If so I'd potentially investigate turning that feature off in your device settings. If that's not possible I'm not sure where to turn, that module allows wlAN driver vendors to put extra features in the are supposed to provid a better user interface... I'd guess that 'better' means 'doesn't work' in your case. Is there anything special about the network you're trying to connect to? WPA2 Enterprise instead of Personal maybe?
