No internet connection and Ralink Wireless Adapter Not Exist

Running: Windows Vista 32bit
Asus P5ND Motherboard (Nvidia Network Controller built-in)

If you need any more information about the computer I can post. I thought this was all that was relevant to the issue.

I came home about a week ago and turned on my desktop computer to find that it would no longer detect being connected to the router despite being physically connected with an ethernet cable (and thus had no internet). Looked at the back of the computer and the light was on recognizing that the cable was in it, but still would not find router.

Checked my other computer, a laptop and it could still connect wirelessly to the router. I thought maybe it was the cable. I disabled the wireless on the laptop and plugged the ethernet cable that was in the desktop into the laptop. The laptop was able to connect through the ethernet to the internet. So it's not the cable.

I uninstalled the ethernet adapter under network adapters, rebooted, and reinstalled. Still no connection. It is part of the motherboard, so I am unable to physically take it out.

I ordered a wireless card (Ralink wireless adapter, $15 on Newegg http://www.newegg.com/Product/Product.aspx?Item=N82E16833166021 ) to hopefully take over for the ethernet card on my desktop as I needed to get one soon for logistical purposes anyway. Installed the driver for the wireless card, powered down, disconnected power, installed wireless card in available PCI slot, reconnected power, booted back up.

Desktop did not immediately detect new hardware which I thought was strange but maybe nothing. In the tray next to the clock, there is a black icon. When I hover over it, it says ''Ralink Wireless Adapter Not Exist''. Neither of the two lights on the wireless adapter come on upon powering up (I would imagine that one is to show that it is powered and the other is to show connection but can't confirm with manual).

Please help. I am to the point where I was about to do a clean install of Vista and cross my fingers that that will solve the problem.

You need to enter the wireless key from your router once before the adapter will connect. The key is either on the label on the router or in the wireless section of the router.

Sony UWA-NA1 - no available driver for Windows? what specs does it have? It seems that with a Giga Juke Hifi-stereo, it will only communicate with WEP encryption, but the Wireless Giga Juke player station...


I found it! Sony UWA-NA1 USB Wireless Adaptor is a OEM products of Quanta Microsystems Inc, it's using the same USB adaptor as Ralink RT73 USB Wireless LAN card with RT2571WF chipset. I did it work ok in window 7 64-bit. But in the link below, its support XP, Vista as well.
1. Download Drivers for XP/Vista/Win7 here: http://www.station-drivers.com/page/ralink.htmChoose Ralink RT257x/RT2671/RT520x (RT73 series USB Wireless LAN)
2. After download it, run it to install the Ralink Wireless App, check for the driver only. When it done, find the folder it has installed. 3. Open device manager in window managerment, choose the Wireless USB (have no driver with yellow !), right-click, update driver software..
3.a Click "Let me pick from a list of device drivers on my computer". Find the "Network adaptor" in the category devices list, click on it, OK.
3.b In a new window name "Select Network Adapter", choose "Have Disk..." then browse the path of folder Ralink has installed. Your will see a file "netr7364.inf" (may be in XP-32bit or Win7 32bit you will a difference *.inf file). Click on it, click open, then OK.
3.c In the left box, find Ralink Technology Corp. click on it, the find RT73 USB Wireless LAN card, then click NEXT, a "Update Driver Warning" pop-up will appears, just click yes. Then windows will install the driver for Sony UWA-NA1 as "RT73 USB Wireless Card". Good luck! (You may try another devices in the list at your own at risk)P/s: Sorry for my bad english! English is not my primary language.

Ralink wireless lan card not exist


You have to remove the PCI card or USB from the computer, uninstall the software. Reboot, now install the software. Power off computer. Install network card or USB, then power on computer.

The key is that you have to install software before installing hardware.

General Networking question


lets see here, your NVIDIA thing is for your ethernet port in your computer.

the wireless PCI adapter, is well, a wireless adapter, its used to connect your wireless, and a 1394 Net Adaptor Connection is basically Win2k/XP's way of telling you that you have a Firewire interface installed in your system.

so, if your going wireless, you dont need NVIDIA, and as your device manager shows that it has a red x on it, it shows that its disabled. as for everything else, i wouldent worry about it.

ECS GeForce6100SM-M Onboard Network Adapter does not show up in windows???


I had the same problem. Tyr this.. Install windows x64 1st install the ide driver (it's a setup program) reboot 2nd go to device manager, you will see a PCI bridge device, update that driver to the lan driver on the cd. reboot Then install the rest of the drivers. If you don't do it in that order you will NEVER be able to install the Lan driver without reinstalling windows.
