Acer Iconia W700 Wi-Fi problem

Hi everyone,


Yesterday, I bought an Acer Iconia W700 tablet and for some reason, the wi-fi disconnets all the time. If I have the tablet really close to the wi-fi spot, it work fine but when I go to my living room, the internet disconnets or it get's limited. The farest thing I can do is open google and search for something. Then the internet crashes..

It's frustrating these situation... And I was wondering if I have to return it or if there is any thing I can do to fix it. I also saw other users online complaining about the same problem...


Thanks for the help!

[ Edited ]

I would like to contribute to this thread.


I have tried the following steps which have resolved the issue for me:


Download the latest driver from Acer Support site.


- Please make sure the version of the Wirelesss Lan Driver to be downloaded  is:

As this is a combo dirver it will also upgrade the bluetooth to Hence the big filesize 220MB.

- Go into control panel and remove the current wireless lan + bluetooth drivers.

- Once removed you can go through and install the newest downloaded driver.

- Restart tablet after installation

Re: Acer Iconia W700 Wi-Fi problem

Thanks for all the suggestions about the wifi driver.  I'm happy to say that my wifi issue is finally fixed.  My third attempt to update the wifi driver seems to have worked. 


It looks like there are multiple ways to update the wifi driver, not all of which work completely.  Previously, I though that I had successfully updated the driver since I saw the new driver version number (i.e. and date (i.e. 11/23/2012).  On my 1st and 2nd try to update the driver, I went tot he Device Manager and clicked "uninstall" on the driver tab for the wifi adaptor and checked the box that said to delete the driver.  I then proceeded to install the new Atheros driver by clicking the "setup" application that came in the new driver.   Appearently that does NOT completely uninstall the old driver.


For my third successful attempt, I did the following:

  1. Went to Control Panel > Programs and Features and uninstalled "Qualcomm Atheros WLAN and Bluetooth Client Installation Program"
  2. From Settings > PC Info > Device Manager > Network Adaptors > Qualcomm Atheros AR5BMD222 Wireless Network Adpator > Properties > Driver I clicked "Unistall" and checked the "delete the driver software for this device" checkbox.
  3. After the uninstall finished, from the Device Manager window I selected Action > Scan for Hardware Changes.
  4. A new unrecognized device showed up in the device manager list. I selected the properties screen for this new unknown device and selected install driver.
  5. I then selected the unzipped Qualcomm Atheros driver directory and clicked Install. 
  6. After the driver finished installing, I rebooted and have had zero disconnects ever since. 

Appearently it is possible to show the latest driver and NOT have the part of the fix that affects the dropped WIFI connections.  You must ensure that you completely remove the old driver before trying to install the new one. 


thanks again for the help!

You should probably call technical support, maybe they can help you get it worked otu since it is still under warranty.

Well You could always try and use (Windows key and X) click on the Device manager then go under the network adapters and right click the wireless card and uninstall the driver (do no click the check box) and reboot and allow it to reinstall the driver. this may help.

Re: Acer Iconia W700 Wi-Fi problem

Hey there,

The wifi problem (random deconnections) is mainly caused by the sleep mode and the wifi 802.11n.

All you have to do is to force the connection to a 802.11g from your tablet and your internet spot. It worked for me Smiley Wink

I don't know whether my explanations are clear enough or not sorry my bad english.

Re: Acer Iconia W700 Wi-Fi problem

Hi all,


I'm having the same issue.

I've tried all the suggestions from another web link and didn't work thus far.

So, how do I force my device to use only in G mode?

I could change from my router but it will affect all other devices which is something I do not desire.

Re: Acer Iconia W700 Wi-Fi problem

This solution from Microsoft's Windows 8 support community seems to have fixed the issue for me:


i went to acer and downloaded the wifi drivers, uninstalled the device in device manger, restart pc, went back to device mmanager and looked for the unknown device. i then right click unknown device and installed the driver from acer.
