Sony Vaio VGNFW378D - Wireless Network Adapter Is Missing From Device Manager
Aug 22, 2011
I have a Sony Vaio VGNFW378D that runs with Windows Vista. Ever since I got this computer (about 2 yrs ago), I have had problems with it suddenly disconnecting from the internet. When this happens it could never detect any wireless networks and I would have to restart the computer to temporarily solve the problem. It usually happened after the computer was in hibernation.
Yesterday this happened again, only this time restarting the computer did not solve the problem. When I could not connect to a network I clicked on "Diagnose why Windows cannot find any additional networks" and it said "Install wireless networking hardware, and verify that the correct drivers are loaded".
I went onto the Sony website to download the Intel Wifi link 5100 AGN wireless LAN Driver and updates. The download was not successful and I received a message indicating that the latest updates of this driver were already installed in my computer.
Representatives at Sony only directed me to links that had steps to finding out what my problem was, which I followed with no success. Most of the steps included enabling the adapter in the device manager, uninstalling and reinstalling the driver, etc...I could not do any of these things because the driver does not appear in the device manager at all.

I have a Sony Vaio Laptop VGN-NS20M and have rebooted it as had a few issues with it. Now the internet drivers have disappeared from device manager. The only thing there related to the internet is under modems. Which has nothing to do with the wifi or the ethernet port.So cannot connect via wireless or the ethernet. Seems strange both have failed. There is no ? or yellow! there, as there is no devices there.I have tried the drivers from the Sony website but they just do nothing, and the troubleshooting from the network icon just says Windows cannot find a driver for your network adapter.Its a dual boot laptop with Vista and Win7 and have the same issues on both OS.

I have a Sony Vaio Model VGN-NS20E (Vista) that has built-in Wireless. The PC was heavily infected by Virus and I had to re-install Vista Operating system. The system is now running fine (picture, DVD drive, sound etc )although, it will not detect the Wireless Adapter, hence the wireless will not work.I went to the manufacturer's computer website and downloaded the driver and (I think ) installed the driver on the laptop.The yellow "wireless" light on the front of laptop is not lit, even though it is switched to on.Am I right in thinking it is the wireless network adapter that isn't working and not the driver as when I go to "Device Manager" and look at the Network Drives, it only shows the wired Ethernet option. This added to the fact the yellow wireless light doesn't come on, on the front makes me think it is the adapter and not the driver.

I just formatted my laptop and realized that the network adapter is missing from my device manager. When I checked with the troubleshooter, it said "Windows did not detect a properly installed network adapter. If you have a network adapter, you will need to re-install the driver". What should i actually do ? I have acer aspire 5742 laptop. I downloaded Acer Aspire 5742 Wireless LAN Driver (Broadcom)Broadcom Wireless LAN Driver 5.100.249.2 23.1 MB from [URL]... into my usb and run the setup file. And restarted the computer. Still nothing has changed. It is not listed in my device manager.

There is no wireless connection icon under network connections neither is there a device listed under network adapters in the device manager. My laptop used to connect to wi-fi but i think somehow the adapter was uninstalled or just plain broke... is there any easy way to find out if i can just reinstall it or if i need a usb adapter now?

I'm trying to install my WMP600N wireless adapter. It's not showing up in my device manager. The thing is I've installed it in the past and ran into some driver issue which made me give up. But it showed up in device manager before so I know it's not a dead card. Right now, plug and play isn't working. How do I get a Wireless Connection to show up in my device manager? This is for my PC. I also have a couple drivers I could use but I don't know how to install them because they are not exe files. I can't select upgrade drivers because the network adapter isn't showing up in the first place.
I have tried unplugging and replugging, and also scanning for hardware changes in device manager.

I'm typing this on my Droid X so pardon the typos. I don't really know where to start or what direction to take so I'll list my major problem, then all the facts/info/and actions I've taken to attempt to fix the problem.Problem - I can not connect to the internet and no network adapter shows up under device manager I have an Asus 5671 running windows 7. I purchased the unit about a year ago.It's outside of the manufacturers warranty. Power went out about a week and a half ago and I believe this has something to do with the cause of the problem. I have repeatedly spoken to ASUS about this downloaded the network drivers from their site. When I install them I receive no error message saying they were installed incorrectly or failed to install, but my network adapter still does not show up. I have recovered my computer to factory settings and the problem has not gone away.
While attempting to recover my computer to factory settings, I found out it didn't already come with a recovery disk set up, so I followed the prompts to make a recovery disk (after all this trouble was already happening), so I wonder if creating a recovery disk was pointless since the network issue was already present. I have my router hard lined to my computer, and it's wireless on. The wireless works with my PS3. My computer itself is not wireless. Asus first said the problem was 100% digital, now say it's a hardware problem. I was told I will have to buy a new motherboard to fix the issue.

I have an i7-2700K system with MSI Z68A-GD80 MB running on Window 7. Awesome system. Only one issue. The Network Adapter section keeps disappearing from Device Manager, causing my ethernet to fail, no lights on either of the RJ45 ports with cable plugged in. All of the latest drivers are installed. I've Googled it and see others with the same problem and have followed the "temporary" solution - shut down the system, unplug it from the power supply, yank the memory out, press the power button with PSU unplugged to "bleed" the caps (or use the pwr/reset button on the MB before shutting it down), let it sit for several minutes (it takes mine at least an hour, so I'm thinking the system needs to be completely cooled down) and then put it all back together and turn it on. Network Adapter section shows up again, Ethernet lights return, internet works again.
This works until the next time the system shuts down and then I have to do this all over again. Extremely annoying problem. I'm not sure if it's a faulty MB or if there's an actual permanent fix.

can't find my wireless adapter in Device Manager.I was able to detect wireless connectivity yesterday. After we replaced our router, my laptop says my wireless adapter is disabled.I am unable to find the "Manage wireless networks" in Open Network and Sharing Center. My Fn+F2 buttons used to enable and disable wireless is not working either. I tried setting up our previous router but it still won't work. I am using Windows 7. Gateway NV59C.

I can't get my Sony VAIO to connect to the Internet via wireless or ethernet. It was working fine and then suddenly lost all Internet connectivity. Under the status it says "connected with limited access." I have an iPad and my smartphone running on the network so I know it's not a network issue.

i just bought a new Sony Vaio VPCSB 490 X Laptop. I should preface this with the fact that my old vaio i had to get rid of because it stopped connecting to any wireless networks (among other reasons.) I had it looked at and was told the wireless card was broken.
My problem with the new one is that i can only get limited connectivity to the network, even though all other wireless devices in the house are fine. Here's the ip configuration i brought up when the computer was connected to the router with an ethernet cord:
Microsoft Windows [Version 6.1.7601]

Have a desktop computer running xp which is connected to modem and router...Am running a D-link DSL-502T and Linksys wireless-G broadband Router, model :WRT54G.My issue is i can connect to the wireless network through the laptop but when i switch the wireless switch on the laptop every few minutes the desktop PC will drop the connection and display network cable unplugged, then goes back and fourth connecting and disconnecting every few minutes....as soon as i flick wireless switch off on laptop all is fine again.....wireless works as have another laptop running windows 7 pro and can connect mobile phone through wireless and ipad etc...I have had the internet load web pages but connection doesnt stay on...Does the same thing when i try connecting directly using network cable.

I have a Sony Vaio SVE1512B1EW and have connected it to my wireless. Works absolutely fine. However recently whenever I turn on my laptop the Internet will work for 2 minutes and then not work, even though it says its connected at full bar signal. When this happened again I tried the Internet on a different laptop and found that it is not the wireless! What will I do? It's telling me there's a connection but not working?

I know there is internet connection, but the computor won't recognise that fact. when I go to repair the internet connection, I get a message ( windows cannot detect any wired or wireless cards on your machine) things I have done is to download drivers for the ethernet card and also the motherboard chipset to see if that would work, but no change. the yellow question mark is still there.

I am using Dell Inspiron N4010 for more than a year now. It was running good. At office i am using wi -fi and at home i was using through cable connection. Fer last few days my wired connection was not working and i got all cable checked and replaced, but could not solve the problem. Then i found that in device manager, network adapters, its not showing and wired adapter. Only wi-fi and blue tooth adapters are there. I can still connect to internet at office via wi fi but its not working at home now with wired connection.I am not able to understand how it stops working and why its not showing in device manage (Network adapters).Yes one more thing i want to disclose is that earlier i have only one drive i.e. c drive wich few days back i compressed and created another drive.

I use a hardwired Ethernet adapter to connect to the internet from home. I cannot connect to the internet on the N5110 but can connect on my desktop PC. I look at the hardware device manager and cannot find an Ethernet adapter. This leads me to believe something happened to the card. It should show up in the hardware profile. I don't want to use a wireless connection. I want to use my hardwired Ethernet adapter.
How can get the system to recognize the device? I don't need to send it in for repair. There is some work I do that can only be done on this computer.
