Re: Acer wifi limited connectivity issue

What laptop model are you having issues with?

Did the unit ship with Windows 8 or was this an upgrade?

If this is an upgrade, is the unit listed on the Windows 8 Upgrade page as a support unit?


All Windows 8 drivers are uploaded for systems that are eligible for the upgrade program.

Re: Acer wifi limited connectivity issue

I think what Acer-Tommy is trying to say is resinstall or update the driver ;-). This came from another forum but it was the same issue and others said that it worked:




Open computer management
Clicked on device manager
double clicked Atheros AR5BWB222 Wireless Network Adapter
selected driver tab
selected Update Driver...
selected Browse My Computer...
selected Let me pick from a list of device drivers...
selected Have Disk...
navigated to the directory where the win 7 driver was and installed it
(for me the path was C:\Users\myname\Documents\Drivers\Wireless LAN_Atheros_10.0.0.38_W7x64_A\WLAN_Atheros_10.0.0.38_W7x64\ndis6xWin7\netathrx)

driver date: 2/15/12
driver version:

Re: Acer wifi limited connectivity issue

I mean, evidently there is a HUGE PROBLEM with the connectivity issues and seems that it has been happening for a while.

I am in no way computer literate when it comes to drivers or installing them, but since my windows update a few days ago, my aspire V3-771 has had limited connection to the internet, whereas before my connection was very fast and the wifi did not drop at all.


Why can't Acer address this issue? I've downloaded the Live Updater and the HW Detection tools from Acer and it tells me that there is nothing wrong with the atheros AR5BWB222 wireless network adapter, but through my research I see that there is.


Once again, can ACER address this because its becoming increasingly frustrating

Having the same issue with Aspire v3-731, wifi drops every 5-10 minutes.

Removed old and installed wifi/bluetooth driver also updated the bios to latest at support site.

Seems the problem is wie spread. This is my first Acer laptop and is not a good experience!

I did a PC refresh and after doing this a couple times to see the issue, I have finally pinpointed where the culprit lies.


After playing around with my router, uninstalling my anti virus and everything else in between, I found out that the QCA Wifi Driver and the Atheros Blue Tooth Driver are the drivers that have the conflict. In other words, these two drivers are the ones that are making the connection 'limited'.

Everytime I reinstalled these after my PC refresh my computer internet connection became 'limited'. However, after my 3rd PC refresh I decided not to reinstall these drivers. Because of this decision I have had no further issues whatsoever with my internet connection dropping or becoming 'limited' at all. Furthermore, as soon as I boot my computer, the internet is connected, whereas before, with these drivers installed, this was not happening at all.

Clearly, there is a massive issue with these drivers. I had to - as computer illiterate that I am -  figure this out for myself.

In conclusion, I will not be installing any new drivers for my Windows 8 Acer Aspire V3-771, until I get official confirmation from an Acer technician regarding these issues. Clearly there is some major problem as after days of research, I see that so many folk who have Windows 8 are the ones who are suffering from this major malfunction; I'm not sure if it is affecting any other models of Acers laptops/PCs, I just know, from what I had to learn that a lot of folk are having these issues.  And that is not a good thing at all for the brand name of Acer.

I have the same problem with my Aspire V5-571 WIndows 8 64 Bit with the Atheros Wireless LAN Driver that I just bought last week.  I can't stream any videos because it would just pause due to disconnection every 10 minutes.  I am ready to return this laptop but I can't because Microsoft store don't accept returns onced opened. Terrible!


There is an updated Wireless LAN Driver dated 2012/12/04 and I installed that but I am still having issues. Wost than before.  I was so pissed yesterday trying to stream the NFL Sunday Ticket on this laptop because it kept disconnecting every 15 minutes!!!!!  


Someone help!  I tried doing the 'Verify eligibility for In Warranty Phone Support and nothing works.  What's the tech support number?

Re: Acer wifi limited connectivity issue

I am seeing all kinds of problems by consumers related to this.  The only reason I bought a laptop is to use the internet and I can't use it for that main purpose!   ACER should be ashame of themselves.  Talk about a class action law suit waiting to happen.

OK, it seems to be solved for my Aspire v3 -731,

Install new bios (UEFI)

Totally uninstall the old bluetooth and wifi drivers


install the latest bluetooth and wifi driver from support


Working without the dropped connection issues.
