Qualcomm Atheros AR5BWB222 Wireless Network Adapter Issues

I have tried everything and finally switching the black and white wires for the WLan adapter solved the issue.

The problem is not the software but the hardware. The antenna connections of the WiFi module is placed naar the metal protection plate and it is possible that they make contact with the metal plate. The only option is to open the computer, take of the keyboard en see how the connectors are placed. You could see that throughout te opening in the metal plate. The module is placed under the letter W of the keyboard.

For those still having trouble with the Atheros AR5BWB222 wireless drivers, especially on the Acer Aspire V5-573G, this is the solution:

Power saving, but somewhere else than you would think!

All forum threads say that you have to right click the device in the device manager and turn power saver off there.

WRONG

I noticed that my WiFi only crapped out when I wasn't plugged in to the power outlet. Read on to find why.

The solution in Windows 8 is to go to the down left corner (Windows logo), right click, and select 'Power Options' from the popup menu.

You will see three power settings (power saver, balanced and high performance).

You will need to do the next steps for both 'balanced' and 'power saver':

Click 'Change plan settings'.

Now click 'Change advanced power settings'

Now scroll down to 'Wireless adapter settings', and change 'Power saving mode' on battery from 'maximum power saving' to 'maximum performance'. (The reason WiFi keeps working while plugged in, is because the power saving of the adapter is only done when using battery life.)

Remember, do this for both the 'power saver' and 'balanced' power profiles!

I am not sure how much more power the WiFi adapter will use. You may want to try some other options than 'maximum performance' and see at what option wifi keeps working consistently... I just went to maximum performance directly.

After doing all this, restart the laptop, and you SHOULD be fine. :-D

ok so you are saying to choose the old driver

do you remember the steps to do it? :B

I had the same issue on my Acer Aspire laptop.

When I went to the device driver and tried to update it, it also showed me the older driver that was still on the laptop.  I selected that and all was good.
