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

Cadenzza

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:

 

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:

 

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

 

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.
