Okay, this will be a lengthy post, but I'm going to try and get you thorough this :D 

First go to your start screen and type "Network and Sharing Center" then click on the settings option on the right. You will see the result in the left view, click on it.

You will see the name of your network, and you will see "Access type", "HomeGroup", and "Connections" please click on your network name, beside Connections. Please click on "Diagnose" at the bottom, what does it say? Also provide me with the make and model of the notebook.

I've done what you told me to do and it says "problem with wireless adapter or access point". I'm using Acer V5 Touch. Hope you'll reply this message as soon as possible.
By the way,
thanks.

Okay you can tell what kind of card you have by 1 or 2 ways... First way is looking on the bottom of the notebook it will have a sticker somewhere (maybe under the battery and sometimes inside the HD and memory bays) saying "This model contains raido ___________". The second way is just trying each one until it works :D 

And just for you CD:

First off I assume you meant the V5-571PG not 571GP (cause there is no such thing according to Acer)

And this is the driver you want to instal:

Atheros chip http://global-download.acer.com/GDFiles/Driver/Wireless... V5-571PG&OS=ALL&LC=en&BC=ACER&SC=PA_6

Broadcom chip http://global-download.acer.com/GDFiles/Driver/Wireless... V5-571PG&OS=ALL&LC=en&BC=ACER&SC=PA_6

Hello All, I have an Acer v5-471p-6467 touchscreen laptop with the atheros ar5bwb222. When I use my mother's internet connection, it has limited (she has an older belkin router. I just purchased a newer netgear for myself and it works just fine. I have tried to uninstall the included driver and install another. However, I always get the message that the driver I have is more current and the operation aborts. I am highly frustrated!

First off download these (save them do not run them)

Atheros: http://global-download.acer.com/GDFiles/Driver/Wireless... V5-471P&OS=ALL&LC=en&BC=ACER&SC=PA_4
Broadcom: http://global-download.acer.com/GDFiles/Driver/Wireless... V5-471P&OS=ALL&LC=en&BC=ACER&SC=PA_4

Then go to your add/remove programs list (open your charms on the desktop and select settings then select control pannel) and remove your current driver. Restart your machine. Then install the correct driver listed above. (you MUST first uninstall your current driver before installing your new driver which during this time you will not be able to access the internet)

When installing the new driver from the .zip file please be sure to UNZIP first, then just run the setup.exe file from the unziped folder.

If you have the Intel Wireless card you need to download these 2 drivers:
#1 http://global-download.acer.com/GDFiles/Driver/Wireless... V3-571G&OS=8P1&LC=en&BC=ACER&SC=PA_6
#2 http://global-download.acer.com/GDFiles/Driver/WiMax/Wi... V3-571G&OS=8P1&LC=en&BC=ACER&SC=PA_6

Install them in that order. If you have Atheros Wireless card then this is your download:

I've tried the 10.0.0.25 driver from @JefferyD90's link, and updated the bios, and updated the bluetooth driver, and disabled bluetooth. I've tried deleting everything and going down to the 10.0.0.17 driver, but no luck.

I think the problem is simply that these wireless cards stink, but not so bad that they would be replaced under warranty.

Anyone have any good suggestions for wireless cards?

There is nothing wrong with those cards. Yours in perticular might be defective, but nothing wrong with them in general. What isnt working?

In that case it's strange that so many people are ousting probems, It coudl seem like the wifi sesitivity is low. When you are close to the wifi router it's fine, but if you are just 10-20 meter from the router the speed drops dramatically. and a few more meters Awa it Looses connection and freezes.

On Acers recommendation I'm running the 234 qualcomm driver. But according to some unofficial websites the 234 is a win7 driver and win8 require the 239 driver. Whats right and whats wrong?

I have exactly the same problem here. I have an aspire v3 571G, have had it since Jan and nothing I have done so far seems to fix the WiFi. I have tried multiple drivers, upgrading/downgrading them never seemed to change the outcome, constant drops every 5 minutes. Doesn't show a lose in connection or a drop in signal, but downloads and streaming content hang and sometimes fail due to lost connection. Haven't tried the BIOS upgrade but I'm not sure if that will really help. Updated Bluetooth and then shut it off..... no help. Did the power management settings that some have had success with in other forums and this did nothing again. Contacted acer and they said if they serviced it and found it to be a software problem and not hardware they would charge me around £80 for the fix as it isn't covered in the warranty. So fed up with it. If anyone has a possible fix for this please share, I have got to the stage where I will try anything.

Sorry for the long post......

Okay, so let me explain a little bit. When you buy a product, they ship it with the latest drivers as of the time it was manufactured. As time goes on, and as more people use the devices and complain/complement about them the drivers are updated. Almost all updates are done within the first 3 months of sale. I assume most of you didn't go on Acer's website and buy the notebook directly from them, so the chances you got that notebook during its "building" phase is slim to none. Most people buy their notebooks from Wal-Mart, or Target, or even on Amazon of which the retailers wont buy them until they see how they are going to sale. No one would buy a product right off the market without seeing how it sales originally.

Now with this said most of these were manufactured BEFORE Windows 8 even released. So a lot of your systems have Windows 7 drivers, of which they cross their fingers and hope it works. It is STILL up to you to make sure your drivers are up to date and working. This is totally normal. They will make the same physical notebook and offer 2 options a old OS and then a new OS version. This lets people, and manufactures, make the transition more smoothly.

If you need help finding the correct driver send me a message here on TomsHardware. I will no longer be tracking this forum as it has got way out of hand of the Original Poster. Please include your EXACT model of PC with your exact OS.

JefferyD90, you are making this a general issue. It's not. It's very specific. We are very much aware that drivers need updates. The Aspire S7-391 newer shipped with Win7. It only shipped with Win8 according to Acer suppport. Further our S7 was shipped to Acer support and their technicians reinstalled the PC and upgradede/ensured all drivers was updated to the latest supported version. But the problem did not go away.
I've tried the PC at 3 different wifi sites and compared to other laptops. In all cases (and with all drivers) the S7 seems to have a problematic low wifi sensitivity compared to other new and up to 5 years old laptops running Win7 and AppleOS
Would you still claim that we have problem caused by lacking driver updates and not not caused by weak hardware design ?
(It's an Acer Aspire S7-391 w qualcomm atheros wifi chipset)

Here we go. I had, as many others, exactly the same problem you have (or had, don't know if you solved eventually). I have tried ALL drivers release over internet, and read tons of post of ppl suggesting different solutions, but nothing worked for me until I have found the right one on an italian forum (www.pctrio.com).

I have already wrote a post explain what is the real problem and how to solve it...you can find the complete post here:
http://community.acer.com/t5/Notebooks-Netbooks/Acer-wi...

Making a brief resume, just to be sure in case Acer decide to delete the post (I have not been so kind :p ), the real problem is that the driver cannot switch between the two antennas properly, so each time the Diversity take in account, the connection get lost. Right now, at release 10.0.0.251, no driver can solve the problem. The solution is pretty tricky, and maybe a little scary for someone, but it is actually easy and fast: open your laptop, disconnect one on the antennas cable (the black one, the auxillary antenna), put some tape to ensure isolation, close and enjoy.

You will not loose anything, as the Antenna Diversity is something good when properly done, so with two different receivers. In the Qualcomm board is not like that, is one receiver with a signal switch that has a signal loss surely bigger than the double antenna advantage...so don't worry about, you can do it. I did it on mine, and many other people on theirs, right now no one complains and no disconnection at all (yesterday night, for the first time since when I bought this ugly laptop, I have been able to watch a full movie without any disconnection.

I also am having a problem with a qualcomm atheros ar5bwb222 in a new GAteway desktop computer (model dx4380), Windows 8--mine says it cannot find any wireless networks, even though a usb wireless adapter that I have from my old computer, works perfectly. I also have updated the driver to 10.0.0.225 and it has not helped at all. I am hesitant to start taking my computer apart to fiddle with antenna wires.

Well, I've tried all the possible solutions listed in this topic, I own an Aspire V5-552P-X684 Touchscreen (Windows 8 64-bit) with the Atheros AR5BWB222 Wlan card... and the wireless connection keeps failing and failing...

-I've unchecked the box "allow the computer to turn off this device to save power" (doesn't work)
-Try to update the driver to it's most recent version 10.0.0.256 (July 4th 2013) from this link:
http://www.atheros.cz/atheros-wireless-download.php?chi... (doesn't work)
-I try to disconnect one of the two physical antennas from inside the laptop (the black wire) (doesn't work)
-I have updated the BIOS driver (doesn't work)

At this time I don't know what else to do, I have to connect the ethernet cable to my laptop because the wireless connection doesn't work for enough time to see anything in the net... please if you have any suggestion it will be too much appreciated...

Thanks for your help atulmaniya... let me say that the only thing i haven't tried is to upgrade windows 8 to 8.1 and install a driver for that version, i will do it this weekend and let you know if it works at last...
And for other people with the same model of ultrabook (V5-552P-X684) i have to say that any of the other solution have worked on mine's...

thanx again to all of you for your time :)

Hey !!
I forgot to let you know if the windows 8.1 upgrade finally works... The answer is NO...
I called Acer's customer service and they told me to bring the laptop to an authorized repair center in my city, and they also told me that that issue is a recurring problem in that WLAN card...
They change the wireless card and install a Broadcom 4321 AG instead of the Atheros, so it works perfectly right now...

I guess WLAN card's price is around $15.. and you can change it manually, no need a technician...

Before you change the WLAN card:
Try to put the modem-router wifi config to channel 11 instead of auto (by default), just google search according to your router how to do it...this is to avoid any interference with microwaves or something that uses invisible waves at home... give it a try... nothing to lose... good luck buddy !!!

Hi,

Here's what worked for my Acer Aspire V5-552P-X637 (also listed as V5-552P-X440) / Windows 8.1 with the same network adapter. First I uninstalled the driver because I was going to use one of the driver downloads posted here. Instead of using a driver download, in the Device Manager I right clicked on "Network Adapters" and selected "Scan for Hardware..." from popup menu. Network adapter reappeared as device, right clicked it and selected "Update driver software" > "Browse my computer for driver software" > "Let me pick from a list of Drivers on my computer" > there are two drivers listed by default, I selected the second driver and clicked next to install. My laptop hasn't disconnected since!

Before my the driver properties were:
Driver Provider: Microsoft
Driver Date: 5/3/2013
Driver Version: 3.0.1.155
Digital Signer: Microsoft

Now it is updated to below and has not disconnected once:
Driver Provider: Qualcomm Atheros Communications Inc.
Driver Date: 3/11/2013
Driver Version: 10.0.0.234
Digital Signer: Microsoft Windows Hardware Compatibility Publisher


Below are additional steps I took and didn't help prior to changing the driver. I'm not sure if they are necessary but I made sure these steps were still in effect after the driver was changed:

Disable/uncheck the "Allow this computer to turn off this device to save power" option under the Power Management tab of device properties.
AND change the settings here: Control Panel\All Control Panel Items\Power Options\Edit Plan Settings
Click "Change advanced power settings" > select Balance in drop-down menu > click "Wireless Adapter Settings" > "Power Saving Mode" > click "On Battery" > select "Maximum Performance" then click Apply button.
Also repeat these steps for Power Saver option in the drop-down menu.

Hope this is helpful! :D
