Alienware M17X-R3 unable to connect to wireless networks

                I have an Alienware M17X-R3 and I’ve been experiencing several networking problems with it recently- most importantly that I can’t connect to any wireless network. It detects all the networks in the area, but when I select and try to connect to one nothing happens. I can still use a wired Internet connection, though. “Troubleshoot problems” or “Diagnose” just tells me that I have no preferred wireless networks. When I go to the Network and Sharing Center, the “Set up a new connection or network” button doesn’t do anything. When I go from there to “Manage Wireless Networks” the “Add” button doesn’t do anything.

 

                I’ve tried disabling and enabling my DW1501 Wireless-N WLAN Half-Mini Card, and reinstalling the drivers. I’ve disabled the “Allow the computer to turn off this device to save power” option on all my network devices. I’ve used a system restore. I’ve run a scan with Malwarebytes and my computer had crashed by the time I looked at it again thirty or so minutes later; it had tried to restart but was unable to because there was “No bootable device”. I powered it off and started it up again and it worked fine. I also ran a Superantispyware scan that completed successfully without finding anything and immediately crashed, but restarted normally.

               

                A few other things that may or may not be related:

-When I boot I get a message that says “Could not reconnect all network drives”

-When I booted I used to get a message from GoogleCrashHandler64.exe that said “C:\Windows\system32\dbghelp.dll is either not designed to run on Windows or it contains an error.” When I went to msconfig and disabled all non-Microsoft processes under services and startup I no longer got the message.

Re: Alienware M17X-R3 unable to connect to wireless networks

Thanks for your quick response. This happened recently, when we got a new combination modem-router. It's a Netgear DGND3300 RangeMax Dual Band Wireless-N Router. I was able to connect to a school wireless network that was still listed under my "Manage Wireless Network" tab but can't connect to the new wireless router or the school network now since I removed it from the list as part of a troubleshooting procedure.

Re: Alienware M17X-R3 unable to connect to wireless networks

spuriusfelix,

 

The DW1501 Wireless-N WLAN Half-Mini Card adapter works ONLY on the 2.4GHz band.

 

When you setup the wireless router, did you make a spuriusfelix_G network using these Recommended Wireless Router Settings and then make a spuriusfelix_N network?

 

Start, control panel, network and sharing center, click on your connection, click on properties. Make sure your settings match mine.

We set up all the settings as you suggested and I still can't connect. I should also mention that when I go to "Manage Wireless Networks" there are no networks displayed.

Re: Alienware M17X-R3 unable to connect to wireless networks

Thanks again for your time. I checked the connection under the BIOS menu and device manager and they said it was enabled. Windows Mobility Center also said it was on, but not connected. I also set up the power plan as suggested and reset the winsock catalog and it still isn't connecting.

Re: Alienware M17X-R3 unable to connect to wireless networks

spuriusfelix,

 

There was an issue with McAfee a month ago, Software Updates Causes Wireless Connectivity Issue Or Unable to Connect to Internet

 

Go to Drivers & Downloads enter your service tag number, then select your operating system. Under network, you'll find the drivers for your adapter. Download the drivers and save them to your desktop.

 

Make a system restore point.

 

Start, control panel, device manager, network adapters, right click on your adapter, left click uninstall. Tell it to remove the software also.

 

Restart your computer.

 

When you log back in, the new hardware wizard will try to nstall the adapter. It may or may not work. Check in the device manager. If it doesn't install, then use te drivers saved to your desktop.

 

What happens?

Re: Alienware M17X-R3 unable to connect to wireless networks

I don't have McAfee, so that won't be a problem.

I reinstalled the drivers for my network adapter and restarted and I still detect the networks and still can't connect to them.

Re: Alienware M17X-R3 unable to connect to wireless networks

spuriusfelix,

 

Did you log in to your wireless router and set it up?

 

Can you connect to another unsecured network?

 

What virus program and firewall are you using?
