No Networking Connection in Device Manager

Q: No Networking Connection in Device Manager

Hello:
I truly have searched many threads with a variety of search terms and cannot zero in on the exact problem or a potential solution. Here is a concise description:

Old 2002 Dell Dimension 4500 which could not update to Service Pack 2 on Xp Pro. Reformatted and reinstalled operating system. Desktop appears and all functions seem normal except can not connect to Internet. There is an Ethernet connection to the motherboard, and the connection to the net is working (main computer on which I write this is connected via DSL to the net). Device drivers have been installed from CD backup disk, as well as downloaded from Dell support. Have repeated process twice, with same result.

Device Manager does not show an internet connection box; Other devices show four lines, all with yellow question marks. Typing ipconfig /all in the cmd window produces nothing--no error, no listing.

SIW profile program says, under "Network Service", that there is an Ethernet Controller. Clicking on this shows a description with one line saying: Status: "0x01802400 has problem".

Another profile program, Belarc Advisor reports, under "Communications:, the following line: "Network Card MAC 00:00:00:00:00:00".

I am really stuck on how to proceed and solve this problem. Hopefully, with this diagnostic information, some of you more knowledgeable people can help me.

Any advice?
Many thanks, Ken

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

A: No Networking Connection in Device Manager

I would logically guess that either no drivers are installed for the network adapter, the incorrect drivers are installed or the network adapter itself is not functioning.

I would lean toward you're not having istalled all the motherboard drivers and devices because you have so many question marks in your device manager, which doesn't preclude having a dead network adapter because I don't know if a MAC address would be reported by BELARC regardless of identification of the device or not. If it is supposed to, the "flat line" of zeros probably means its dead, if not, drivers.

My Windows 7 Ultimate 32-bit Dell froze completely. After a hard shutdown and restart, the computer wouldn't find my wireless network. It then told me that I have no networking hardware. I then went to the Device Manager and was told that "the specified service does not exist as an installed service." I then tried a System Restore and found that that won't work either. I am baffled as to what happened and what I can do. Any assistance gratefully accepted.

Lets try doing this:

Type this: sfc /scannow

I have an HP dx6500 with the service tag dx6667cl. I'm running Vista ultimate 64 bit. My problem is I can't connect to my home network. It has a wireless card in it but, I don't have a wireless access point. It is the only network device listed in the device manager. I have tried opening the bios but there is no way to enable/disable the integrated nic. I was not able to find any of the integrated devices in the bios. I tried flashing the bios to the newest version. That did not help any.

How do I get Vista to see the wired nic?

I had been using the IE well until yesterday I cannot open any web page. I'm sure the network works fine, because I can receive/send email using outlook. I thought maybe the IE had some problem, so removed the IE 7, downloaded IE 8 using another PC, then installed the IE 8, but it still cannot open any web page. I checked the Network Connections, found "Unavailable - device missing" under MSN Connection manager.

What should I do to solve this problem?

I noticed an icon in my "Network Connections" titled as MSN. It states under "type" that it is a connection manager. The strange thing is that it points to something looking like a telephone number (4255555555) and its status is unavailable due to a missing device...

I don't remember doing anything that could install the above connection...Also scanned my machine with Spybot S&D, Malwarebyte's Antimalware and Commodo Defense+ scanner. None of those programs found anything suspicious.

I accidentally started the msn messenger setup wizard (I don't use it - using windows live messenger) but canceled the setup process almost immediately. Could this be related?

Have you people ever came across this thing? Is it something harmless or should I start posting at the security forums???
 

A:Solved: MSN Connection Manager - device missing

The MSN Connection manager is installed when you start to install MSN Explorer -- Was that the setup wizard you started (has a butterfly icon) rather than MSN Messenger (has an icon of two people)? MSN Explorer is included with XP; MSN Messenger you would have had to download.

The missing device will be displayed if you don't have a dial up modem.

You can right click the Connection Manager and delete it.

To uninstall MSN Explorer, goto Control Panel | Add/Remove Programs. Check if you see MSN there (will be here if updated from the version included with XP).
If not there, click Add/Remove Windows Components, scroll down to MSN Explorer. If checked, uncheck it.

I use an ethernet cable connection, which the ethernet controller also states that there are no drivers; though that might be due to there being no local area connection.

Hi everyone

I have an emachines em350, I installed win7 as a clean install onto a new hard drive.

It's al sweet except the sound and network adapters have not installed. In fact it seems that win7 is declaring they never existed in the first place.

I have retrieved the latest drivers, win7 spits them out stating that the devices are not present. I have tried the older versions using compatibility mode. I have tried install legacy hardware. I have tried to flush them out through command prompt.

Nothing.

The sound 'card' (which I believe to be onboard) is seen by device manager, but refuses to have anything*to do with drivers.

The LAN I also believe is part of the motherboard, but it just won't show at all.

For the love of all that is holy, please help me out if you can or I fear this netbook will be going out the window at a rate of knots.

Thanking you in advance

hi - i was just playing music on my dell latitude e4300 via bluetooth to a belkin bluetooth receiver connected to stereo.

somehow the connection got dropped - during a phone call on a land line. may be irrelevant.

now, i cannot get bluetooth connection back. there is no bluetooth icon in the system tray.

i cannot find 'bluetooth' devices in start>control panel> devices
--i have 2, and both ought to be there.

i unplugged bluetooth receiver, and had win 7 search for devices to add - no luck.

sure, i can reboot, and everything will probably come back.
but i am hoping for a better answer. i don't want to have to reboot every time the bluetooth connection gets lost.

i searched the web for a little, but only found unrelated posts, or posts with no answer. THANKS!
 

A:Bluetooth connection lost, icon gone from system tray, not in device manager

bluetooth light/icon on laptop, not screen is on; no bt

ok, i rebooted, thinking the bluetooth icon would again be in system tray, with the red in the middle, showing i have bluetooth capability, but that sound is not currently being directed to bluetooth.

no icon.

the dell laptop does have bluetooth icon illuminated on the laptop, just above the function keys - not on the screen at all / not in sys tray.

the bluetooth receiver is on, is working.

Two of my USB external Hard drives, a Fantom 600 GB and a Western Digital My Book 500GB cannot be seen in My Computer. I can see them in Device Manager and that says that they are working properly and the drivers are up to Date. In Disk Manager the 2 external drives had a black bar unlike the other drives which had blue bars. The 2 external disks had a number assigned to them but no letter.

I have tried diskpart in the command prompt, was able to assign a letter, then had to format the drives and they did show up in My computer as valid empty external hard drives with the correct amount of space on them. But when I tried to recover the backed up data for one of the disks (less than a third of the capacity of either drive) they went back to not being recognized by My Computer ans in disk manager had a black line with no letter again.

I just went through that process again, got both drives back and tried to recover the backed up files to my Fantom drive and lost the Fantom drive once again.

I am attaching screen shots of my current My Computer (Computer in 7) Device Manager and Disk Manager. In Device Manager you can see the Fantom. The My Book is the WD 5000AAV. In Disk Manager the My Book shows healthy with Disk 1 and the letter L. The Fantom is Disk 2 with no letter and a black bar. In My computer, the My Book is there but not the Fantom.

A:External drives show in Device Manager & Disk Manager but not Computer

Hi Dick1030,

Welcome to Seven Forums.


Please do as follows:

1. It is unusual for the System Reserved Partition to have a drive letter. Please remove the drive letter.

2. Please remove (always Safely Remove) all the external drives including any card reader and do a drive cleanup as indicated here. http://www.sevenforums.com/hardware-devices/298744-usb-thumb-drives-not-recognised-not-drive-letter.html#post2477076 It will clean your system of all non-present devices and you will be starting with a clean slate.(Incidentally this can resolve many drive letter assignment confusion of Windows OS, as you can see in the referenced thread.)

3. After you reboot on completion of the drive cleanup, plugin only your WD My Book and the Fantom drive. As you plug-in the driver for each device will be installed ab-initio. You can watch it.

4. Now take a screenshot of the Disk Management and post. While taking the screenshot, click on "Show/Hide Console Tree” and “Show/Hide Action Pane” buttons on the toolbar on top to hide those and also pull up the center partition line up as much as possible so that we get a clear and full view.





5. Also tell us whether you are sure that you had formatted the Fantom drive and it contains data and whether you want to recover the data..


(Your statements and the screenshots are so confusing - atleast to me - it is necessary that you do the above and restate the problem.)

Yesterday, I started a download and kept the pc on with my Seagate FreeAgent GoFlex External HDD 1TB plugged in. After I woke up I realized that there was a power cut and the computer went off unexpectadly (I had no UPS or any backup system).And, I found that my Ext HDD was not seen in my computer anymore (It was working perfectly until before I went to bed).
In device manager, under 'Disks' it shows 'GoFlex Hard Disk', but in BIOS or Disk Manager there is no sign of this HDD.

I really need the data in the HDD badly. Please help me recover it.
P.S. I read somewhere that keeping the HDD in freezer might help and give a little more time. Is that true? Worth the risk?
 

A:External HDD gets detected in Device Manager but not Disk Manager or seen in 'My Computer'

Power outage probably killed something in the enclosure or its PSU. The drive in the enclosure is probably fine. I would remove the drive from the enclosure and put it in a dock or install it in a desktop computer before considering freezing it. Freezing is usually reserved for click of death drives, and a last ditch effort.

Dell Vostro 1400, Core2Duo. Installed Windows 7 64 bit a year and a half ago. For those not familiar, the Vostro is not entirely compatible with 64 bit, so the drivers are a little hit and miss.

Computer runs slow sometimes, has since the install. I don't think I've ever seen the yellow triangles before, but I may have never looked at the device manager ... the computer is a secondary machine in the house.

My question is, do these indicate a performance problem or can I ignore them and assume the computer is working as best it can?

The AUDIO FADE PROBLEM is an issue with this laptop and I am wondering if it is related to the above.
I have upgraded to the latest BIOS and drivers using the Dell Product Support pages.
Every other day I have to reinstall the Realtek Audio Device to get audio from streaming media.
The current Driver Version is 6.0.1.7908 from Realtek Semiconductor Corp. Date 12/08/2016 which is what it defaults to upon reinstall.
I suspect that for whatever reason Dell has not yet come up with a fix. Has it something to do with the fact that although I bought the laptop new, it had been upgraded from Windows 8 to 10? (A fact that I only discovered later)

Not sure which forum category I should use, thus using software (for Driver Problems).  Various times to fix a device you can go into Device Manager  and uninstall the driver, go to top of page click on Actions and click on Search For New Devices.  I am under the impression this will uninstall the device driver, then reinstall the exact same driver (code).  Why does this work?  It appears that the exact same code is now reinstalled and many times fixes a problem.  I have used this technique on mouse driver, internet driver, keyboard driver.  THis is a good and easy first process to try and make a quick fix.
 
Again, I am just trying to figure out why it works - I know I am missing something.  As an ex-programmer trying to figure out why the same code now will work when it had stopped working.
 
Why or under what circumstances does the driver code stop working, and then why does a reinstall of it at times lets it start working again.

drivers but remain greyed out/hidden. Windows & IOS are up-to-date. Phone works perfectly fine on old laptop so I know it's not the phone and the connectors. Grateful for advice that's more than the basic Apple advice. Many thanks.

i have installed the correct driver for this belkin bluetooth usb dongle model: F8T012XX1

but in device manager, it has the belkin device and microsoft bluetooth enumerator, which is great. but when u get further down the list. it has a tab named "other devices" and then a subtab with "bluetooth peripheral device" which has an exclemation mark on it.

i have searched for driver software using the update service but it cant find no update.

i have looked for the name of the manufacturer but found nothing.

i then disabled the unknown device, and sent a picture to my mobile phone. which confirmed that it was not the belkin bluetooth device. so i uninstalled the unknown device, restarted the computer. then when i logged in, it said that it had found a new device and wanted me to find the CD that came with it..

i would be greatful if any1 could help me on this..

thanks in advance

Hi,
My 7270 latitude touch screen stopped working shortly after first use (after win update worked again but for a short time).
All drivers are up to date.
In device manager a USB device shows as unknown (yellow warning triangle), otherwise there are no indications to the source of the problem.  There is no other touch screen device showing in device manager. 
How do I perminently solve this?
Thanks

How do i figure out what driver or even component windows wants software for when in the device manager under other devices it lists an unknown device and windows update cannot find anything.

Oh and is it appropriate for me to use this topic to ask another question regarding explorer.exe as while i am inside a folder i delete (by choosing delete from the context menu in the tree view) while inside that folder on this particular laptop PC explorer. always crashes, collect information, sends it and restarts explorer. I have not experienced this problem on any other pc running any version of windows 7, oh and the same happened with build 7264 x32 and the current install of build 7600 x64.

I am having an issue where my DVD/CD RW has a code 19 error in device manager. The drive still works as I used it to boot a Windows CD and run a startup repair to see if that found anything. I tried uninstalling the drive and then scanning and it failed to install the drive. I also tried uninstalling the drive and rebooting, but it wouldn't install. Any suggestions?

Hi everybody.

I just bought myself a Powercolor Radeon HD 4890 yesterday. After installing the card and the required drivers everything works like a charm. However, every time I start up my PC I get a message saying that a new device has been found on my system. On checking Device Manager I found an "Unknown device" entry under "Other devices".

I'm attaching a screenshot of Device Manager.

Are there any drivers I'm missing? It only happened after removing my old card (after uninstalling all its drivers) and installing the Radeon.

Any help is greatly appreciated.

Thanks.
 

A:Unknown Device In Device Manager After Installing Radeon HD 4890

I have a Powercolor Radeon HD 4890 (I also have a Gigabyte 4890 and XFX 4890 in two other PCs). I think you need to install the latest ATI Catalyst Suite. You may have installed the driver only package. Anyway, I think it has to do with the HDMI capabilities of the card. High def sound is built into the card (the HD part of the card name) and the HD sound driver is part of the Catalyst Suite. When you use an HDMI cable to an appropriate display, HD sound is also transmitted through the same cable from the Radeon graphics card.

Of course, be sure to install .NET Framework 2.0 as it is required before you can install the full Catalyst Suite. The HD sound driver won't install without it. At least I had trouble before I installed .NET 3.5. I went to Windows Update and installed .NET Framework 3.5. 2.0 is included in that update and 2.0 wasn't available separately.

I have a Toshiba laptop, model L505-ES5018. I had Windows 7 Home Premium 64 bit installed on here, but decided to reformat my hard drive using Windows 7 Ultimate 64 bit. After the reformat was finished, I ran Windows Update and it found several items to download and install for me. I noticed that it also found optional items to download and install for me, so after all the important updates installed, I ran the optional updates. After all of this installed, I checked Device Manager to see if there were any errors and I found nothing. I assumed everything was fine. I decided to check Devices and Printers and under my laptop icon, there was a yellow icon with an exclamation point on it. I decided to run the troubleshooting option when I right-clicked the icon....it gave me a solution to download a Toshiba password utility program, so I did that and nothing happened, even after restart. Same icon appeared. When I clicked on the icon a second time, I noticed that the model of my computer at the bottom of this window, changed from L505 to TIAS. I have no idea what this is. I decided to do another reformat on my hard drive. This time, I ignored the optional updates. I checked Devices and Printers again, the same icon appeared but the model of my computer said L505, like it should. There is something in the optional updates that is changing this. Could it be the Intel chipset driver that the optional update is pushing? I'm not sure. I went back to Device Manager, th... Read more

Hello,
My integrated speakers and audio port do not seem to be working. It happened after I was playing around with bluetooth trying to get that to work. Now only bluetooth is able to connect. 
So far I have tried:
System restore
Deleting and redownloading audio drivers
Adding legacy hardware for Realtek
ePSA test was able to hear the tones
The audio logo has a red X through it and only the bluetooth headphones drivers appear in device manager. Any ideas what might be the issue and how to solve them?

My touchpad somehow didn't have a scroll up/down feature. I tried to install a new driver from HP website. Now, the touchpad has stopped working entirely and the touchpad device is not visible in the device manager nor in the mouse settings. I installed a number of drivers and updated drivers again but to no avail. Please guide (step-by-step) as to how should I proceed after downloading the requisite driver.

I had some trouble last night and today with getting rid of a virus. Now that it is gone, I am having sound problems (maybe related, maybe not). This morning, when I opened iTunes I got a message that there was no audio device detected. After trying several things, I rebooted. Magically, I could play music again. However, a short while later, I again got an error message telling me that there is no audio device found, even though it shows up in Device Manager as working properly. The problem goes away for a short time after I reboot, but returns. It is Realtek AC 97. Why won't my computer keep recognizing it?

(It tried going to Realtek's site to download an update. It has updates for Windows 98, 95, etc., but not for XP. Or at least I couldn't find it.)

Hello,
I recently put together a new computer, and in the process of of installing the USB 3.0 connector from the front of my GX500 case, I either bent numerous pins on the motherboard USB 3.0 header or the motherboard shipped that way and I inadvertently made matters worse. Anyway, that header on the motherboard is without a doubt unusable.
Since I don't really need the USB 3.0 functionality, I bought a USB 3.0 -> 2.0 adapter cable, connected one end to the connector on the front of the case and the other end into the USB 2.0/1.1 header on the motherboard. Unfortunately, when Windows 7 boots and I plug a device into the front ports of the case, Windows detects the front USB ports as "Unknown Device" within Device Manager yet says the driver is successfully installed. I've already downloaded the most current Intel chipset drivers for my motherboard, deleted and reinstalled all USB drivers, and all rear USB connections are working perfectly fine - it's just the two front ports that are connected from the case to the USB 2.0/1.1 ports via the adapter cable.  I've tried both USB 2.0/1.1 headers on the motherboard, and I've tried plugging in several devices to the front USB ports, and this problem still persists.
I've ensured the connection inside the case is solid, yet I cannot get Windows to recognize the front USB ports.  However, I have confirmed that power is being sent to the front ports because it charges my phone when I connect it to the front USB ports via m... Read more
