The network adapter on my desktop stopped working, and it has no PCI slots, so I picked up a Gigaware "USB to Ethernet Adapter" from RadioShack. There's no product number, just the name.

 

Using this adapter I'm unable to connect to the internet (Windows 7), while another computer using the same Ethernet cable connects just fine. The troubleshooter tells me the adapter ("Local Area Connection 2") "doesn't have a valid IP configuration." I have tried setting the IP and DNS manually. If I do so it still doesn't work, and the troubleshooter cannot identify the problem.

 

I have tried using the same adapter on a laptop. The laptop had the exact same problem, being unable to connect, until I turned the Wi-Fi on. At that point, for some reason, having the Wi-Fi for our network on allowed the adapter to auto-configure itself to connect to the same network. Now, when used with the laptop, the adapter works permanently, even with the Wi-Fi switched off.

 

I can't figure out how to fix this on the desktop. The desktop doesn't have Wi-Fi, so I can't use the same solution as with the laptop. If you think the adapter is hopeless I'm open to buying a different one online, or even replacing the desktop. You can find the results of the command "ipconfig /all" here: http://pastebin.com/JedsZMxE

Did you set it to a private network? Or tell it to obtain an IP address when it connects?

 

Okay, just read what you said about the laptop. I think this adapter is a WiFi adapter with a cord connected where the antenna would be, lol. You may want to try configuring like a standard WiFi device?

 

And also, did you try looking at it like a storage drive? The drivers, at least I can see, are on the stick like a USB pen drive.

Sorry if I snap at you. I can't stand stupid for more than 5 minutes at a time.

Right now it's set as a public network. I'm not sure how to change that, but does it matter?

 

This is the IP setting that I tried changing: http://i.imgur.com/QZgueWH.jpg It didn't work, so I changed it back.

 

You're right about the USB drive part. It appears in My Computer as a CD drive, with an autorun program that sets up the driver. It also includes a .cat and a .inf file.

 

If it's actually a Wi-Fi adapter, it doesn't look like it in the network settings. It appears as a standard LAN connection, with no wireless settings or anything.

Sounds like the driver didn't install, or didn't install properly. Try clicking on the autorun program.

 

If you open the Network and Sharing Center, does it appear there? If you go into Device Manager, does it appear under network adapters there?

The driver is definitely installed; the program says so and I can see it in System32/Drivers.

 

It appears in Network and Sharing Center as a LAN connection: "Unidentified network." It also appears under network adapters in Device Manager.

Hmm. Have you tried using the USB connector on another computer?

 

From the first screen shot, it's clear that the connector isn't seeing your network, because it's defaulted to the APIPA address of 169.254.x.x. That's also the default IP address when you set up a workgroup. You may have to use "set up a new network or connection" in the Network and Sharing Center.

I've tried it with another computer. Info in the OP.

This appears to be a known issue with Gigaware adapters. Try right-clicking on the device when it's plugged in, click on Explore, and in Windows Explorer you should see the Windows and Mac drivers. The drivers are there, but seems they don't necessarily auto-install. Scroll down to read the reviews: http://www.buzzillions.com/reviews/gigaware-usb-ethernet-adapter-reviews

 

If it still doesn't work, it may not be compatible with Windows 7.

“The network adapter on my desktop stopped working”

--- I see it has a Win7 OS but is it an upgrade from XP or Vista?

--- Have you tried troubleshooting the network adapter?
