We have an Acer Aspire X3910-U3012 desktop that runs Windows 7.  To our knowledge, there has not been any power outages, lightning strikes, or viruses that would affect the computer.  I’m not sure what other information is pertinent, so please let me know if there is anything else that would clarify that problem.

About a week ago our computer no longer allowed us to go online through our wifi.  It does not work on Internet Explorer, Chrome, or Firefox.  It claimed that there were “no network connections available” and we could not see out wireless signal on the list of available networks.  Our laptop worked fine connecting to the internet using the wireless signal.  We searched online for suggestions, yet most have not panned out.

 

We ‘troubleshooted’ the issue, yet it claimed that the “a network cable is not properly plugged or may be broken.”  The thing is, we have always used that computer’s wireless and has never had this issue before. 

 

 

We called our internet service provider and they had us plug the computer into our ethernet cable and we could connect to the internet via that, so they told us it was a problem with our computer, most likely with our wireless network driver.

 

As per some suggestions, we looked at the Network Connections and our Wireless Network Connection does not even show up there.  We only see the Local Area Connection. 

 

 

We tried to ‘update the driver software’ under the Device Manager, yet that appeared to have no changes.  It just looks like the LAN wireless is nowhere listed on the device manager. 

 

 

Please, we have been trying to solve this for about a week and still have been hitting a brick wall.  Any suggestions would be greatly appreciated!

Hello, and Welcome

 

First open Device Manager and click on your PC at the top of the tree. Select Scan for Hardware Changes and see if the Wireless Adapter is detected under Network Adapters. Are there any yellow exclamation marks listed in Device Manager?

 

Type CMD in the search box Right click > Run as Administrator and type the following command

 

ipconfig /all   <enter>

 

Copy and past the results in your next post. Is your Wireless Adapter listed? 

 

You may need to reset the wireless card. Open the case after removing the power. Touch bare metal of the case first and re-seat the wireless card. Here is your service manual.

I just wanted to thank you for taking the time to help.  In lieu of opening up the computer, we ended up getting a USB wireless adapter and so far that has fixed the problem.
