I havea Dell Studio XPS 8100 with 64 bit operating system, running Windows 7 HomePremium w/ Service Pack 1. I purchased the computer in January 2011.
AfterI purchased the computer I purchased a NETGEAR Wireless Router to set up aWireless connection to two Lap Top computers but since my Desktop was merelytwo feet from the Router I hard wired it to the Router with an Ethernet Cable.
Irecently moved to a new location and found that I had to connect the XPSA 8100to a Wireless Router. I purchased a newer NETGEAR 27, and had no issuesconnecting the Laptop Computers to the new Router regardless of the distancefrom the router.
WhenI attempted to make a Wireless connection to the XPS 8100, It gave me a message“Microsoft Virtual WIFI Miniport Adapter Unable to Connect with a CODE 31”.
In reviewingmy Network Adapters I found both the “Microsoft Virtual WIFI Miniport Adapter”,and a “DW1525 (802.11n) WLAN PCIe Card” Status indicated they were not workingproperly.
Iwas able to visit the DELL website and reinstalled both the Microsoft VirtualWIFI Miniport Adapter and the DW1525 WLAN Card. Now they both indicted thatthey ARE working properly. I also located two Antennae’s that came with theDesk top and I installed them on the machine.
HoweverI still cannot get a Wireless connection to the Router and I currently have thecomputer sitting merely 3 feet from the Router. I continue to receive an “Unableto Connect Prompt”.
Can you connect in the same room as the router?
Go to Drivers & Downloads enter your service tag. Then select your operating system. Under network, download and save the drivers to your desktop.
Make a system restore point.
Start, control panel, device manager, network, right click on DW1525 (802.11n) WLAN PCIe Card, left click uninstall. Tell it to remove the drivers and software.
Restart your computer.
When you log back in, then new hardware wizard will try to install the adapter and drivers. Look and see if it installed in the device manager. If it didn't then install the drivers from the desktop.
What is a Dell Service Tag and how do I locate it?

Welcome to the Community.
You will have to have the Microsoft Virtual WiFi Miniport Adapter, both disabled and removed, as it is going to interfere when the wireless adapter is trying to connect to the wireless network.
Please open command prompt as administrator, and type in these two commands and hit enter one after another:-
netsh wlan stop hostednetwork
netsh wlan set hostednetwork mode=disallow
Restart the computer. Delete the old profile on the wireless adapter or refresh the wireless card driver. Establish a new wireless connection with the router.
Please reply with results.
Thanks and Regards,

Did you recently install/reinstall the operating system?
Can you run an ipconfig /all log and post it back here.
I completed the steps as you instructed except I could not find the wireless adapters' old profile, but where you suggested to refresh the wireless driver I did an update and it prompted that my driver was up to date. However after restarting the computer I attempted to connect to the Router but it still will not connect. I am currently connected through an ethernet cable; I did disconnect the ethernet cable before I attempted the connection.
No, the operating system has not been reinstalled. Here is a copy of the log:

I currently have the desktop situated about two feet from the router so I can use it with the ethernet cable, and have been attempting to establish the wireless connection before I move it to another room.
I attempt to do the steps as you have instructed. But first I will run a current Back-up.
That's why I asked you to make a system restore point. If it doesn't work, you can come back to what you have.
Have seen members with desktop wireless adapters and they forgot to put the antenna(s) on the adapter. Do you see antenna(s)?
Yes, I do have the Antennas installed. I followed your instruction and I now have a connection. THANK YOU MUCH FOR YOUR HELP!
Glad you got it working! Thanks for posting back.
