Laptop wireless doesn't work after device reinstall
Hi all,
I had consistent problems with Limited Access and losing connection in general on my one-year-old Samsung laptop. After trying various fixes, with none of them working as needed, I eventually decided to try to uninstall the wireless device, as suggested here. And following the described procedure I expected the device to reinstall after reboot and to have wireless access once again, whether that solved the mentioned problem or not. Procedure was: Device Manager > Select device (Qualcomm Atheros AR9485WB-EG Wireless Network Adapter) > Right click "uninstall" and the device was removed.
However, after Windows installed available drivers after startup (v10.0.250 or something of sort), I couldn't connect to home wireless network. Check the Image-1 to see the dialog box in lower right. I updated the drivers to the latest ones I could find, even before uninstalling, but it didn't help. I pulled out a cable, connected and right now I'm ~7 hours total searching for a fix and I finally decided to come to you all as there's nothing I could find to fix it myself. Below are some info that might be relevant.
1. System: Windows 7 Professional, 32 bit
Laptop model: Samsung NP270E5V - X01HS
Network Adapter: Qualcomm Atheros AR9485WB-EG Wireless Network Adapter (current driver v9.2.0.470)
Network Adapter Hardware ID:
2. One of the fixes for the Limited Access problem suggested to disable Microsoft Virtual Wifi Miniport Adapter or something of sort. Don't really remember as I didn't pay much attention to it. My Network and Sharing Center showed four connections previously and one was disabled after turning off that device. Now, after reinstall of Atheros device, neither Miniport Adapter nor related network show anywhere (Device Manager or Network and Sharing Center).PCI\VEN_168C&DEV_0032&SUBSYS_4105144D&REV_01

3. I tried to uninstall the device again and "Scan for hardware changes" before reboot as suggested somewhere else. After that the device received "#2" after its name in Device Manager window (see here). And now I can't update drivers as I get the following message.
4. As far as I can tell, the device is enabled (see Image-1 above). I tried disabling and enabling but didn't help. However, ipconfig/all shows various disabled/ media disconnected statuses:
Some of laptop's Fn + Fx combinations aren't working - particularly one for turning on/off the wireless (from what I can tell) - as I didn't previously install the necessary software to configure them. Now that I tried, it's Samsung's "Easy Settings" utility (v 2.0.0.45) which won't start at all. I'll try compatibility mode and to install older version in hope it will give more clues as to what's wrong.Microsoft Windows [Version 6.1.7601]

5. I tried installing drivers Samsung's "SW Update" utility suggests but installation always fails. It failed even before the Windows' ones did. Also, it suggested to try manual installation so I downloaded driver in question but it's a package with two older version drivers - v9.2.0.500 and v10.0.0.67 - which can't be installed as nothing happens after waiting for a minute.
6. Lastly, Atheros Client performed some tests and gave following results:
This is all I can tell you for now. If you have any questions I'll try to offer the best answer I can.Driver installation test
This test is to check the radio driver installation.
The radio's registry keys are OK.
The radio driver has been installed.
Card insertion test
This test is to check the radio insertion.
The radio has been inserted.
Card enable test
This test is to check if the radio/driver is enabled.
The card is not enabled
Enable the card.
Association test
This test is to check your client adapter's association to an access point.
Link Status . . . . . . . : Not Associated
Your client adapter is not associated to an access point.
Configure the radio card and set SSID and other properties.
Authentication test
This test is to check authentication.
Authentication test bypassed, because authentication is not in use.
Network test
This test is to check your network settings.
You have not configured your computer to use the client adapter.
I really hope you'll be able to help me as my first next solution is Acronis Restore to a 8 month old backup, and final solution is Windows reinstall, neither of which I'm too fond at the moment.
