wired connection not seen in device manager

Q: wired connection not seen in device manager

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 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.)

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
 

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.

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.

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!

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.

Might be a stoopid question ...

My XBox360 is wired by ethernet into my home network (via Devolo homeplug behind TV).

My music server (Win7 netbook) is not wired, but on the wireless network.

Can I get the XBox to "see" the media folders on the netbook (to play music etc.) using this setup or do I have to have both clients on the same wireless network ?

The Xbox automatically disconnects from the wireless network when ethernet is used.

Hi,
I have windows 7 Pro installed. I have a DSL connection that requires a username and password. I have read the tutorials for setting up ICS in windows 7, but it is not working for me. In my 'change adapter settings' page, I have 3 connections: LAN, Wireless and M 1 (this is the dial-up for the username and password). Here's what I have done:

I have enabled ICS for M 1, and created an ad-hoc wireless connection called 'M network'. I basically want to share my wired connection with my iPhone. Everything is ok as far as connecting my iPhone to M network, but when I try to use the internet, all i get is a 'connecting' message on my phone, and it doesnt go any further. I have used this network before to connect 'air mouse' on my phone that lets me use my phone as a touchpad. It still works fine that way, but I cant use internet.

I have even tried enabling the ICS on LAN instead, but got the same results.

Am I doing something wrong?

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.

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.

I've had this problem for a while now, and until recently, I was fine with having my wired adapter disabled. But now I want to use this computer to use ICS.

This has been a problem for as long as I can remember using my computer in this house. There's actually a few different things that happen, but I feel certain that they are related.

I have my computer connected wirelessly to the houses main router which provides internet access. I have plugged into my computer a connection to a switch in my room. Regardless of whether or not something else is connected to the switch, I often can't access the internet while it's plugged into the switch. Sometimes I can, but I'm not sure what situation allows me to do so. I just keep disabling the adapter or unplugging and replugging it or switching off the switch or some combination of the three until it lets me use the internet while being connected to the wired connection.

Even when it does work, it tends to be quite slow and drop out for short, irregular periods.

I have a PS3 connected to the switch, which I want to be able to go onto the internet with using the wires (keeping the wireless free to be used for AdHocParty).

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)

I started disabling all the devices one by one and I finally narrowed down the culprit: USB Connect Managers -> UCM-UCSI ACPI Device  (Hardware Id: ACPI\VEN_USB&DEV_C000) This device, when active, keeps appearing and disappearing from the device manager tree forcing a refresh every few seconds.And it only happens when my Lenovo Thunderbolt Dock (40AN0230US) is connected. When I disconnect the dock the driver stops disappearing and becomes stable. Opening the driver Properties -> Details I get: Status: 01802400 (DN_HAS_PROBLEM)Problem code: 00000016 Any idea what is going on?

Model is Acer Aspire One D270.
Internal bluetooth doesn't work.
Nothing in device manager.
Fn+F3 is meant to control it, but doesn't.
May be because I've messed with some programs.
Trying to re-install to factory settings.
Any suggestions at all?

thanks

What programs did you remove or mess with? Have you tried repairing these programs?

Hi Malware Specialist!

I started out in the "Am I infected?" Forum and a junior specialist sent me here to get further help, here is the link to the 4 logs I ran for him:
http://www.bleepingcomputer.com/forums/topic428124.html/page__p__2477667__hl__polarsnowfall__fromsearch__1#entry2477667

For several days I have been trying to complete the preliminary steps required by this forum, I can not back up to windows/microsoft program (Backup Configuration not valid 0X8100029), but hopefully the two other programs I used were successful, namely cobaine and driveimage. At the end of the driveimage session, it frozen and there was "Globalroot\device" followed by various endings. Then it completed and said finished. Also it went to blue screen the firsttime I tried to run GMER and rebooted.

The main problems of slow programs from startup, no devices in device manager, no audio device and no printing capability began after I ran some kids software games that kinda of frozen the computer, although I believe whatever is making my computer upset has been there for awhile and may have something to do with remnants of roxio 2009 and other shared folders. In services it says "Configuration Manager machine selected for remote communication is not available at this time."

I've got a regular desktop pc and a laptop. Both are running Windows 7.

If both machines are wired, file and printer sharing works like expected. If the laptop is on the wireless, things go sour...

The machines don't see each other, I can't ping the laptop from the desktop or vice versa. Strangely enough, if I ping the desktop from the laptop by IP address the desktop will reply. At that point the desktop will see the laptop too and sharing (file, printer & media) works fine. But if the connection is idle for a couple of minutes they won't see each other anymore.

I've tried all kinds of things: disabled IPv6 on both, reconfigured file and printer sharing, disabled the firewalls on both. But none of these changes have had any effect whatsoever. I have also tried to give everything the same name (SSID, workgroup and network name on the desktop) but that had no effect either.

More info:
- Wired and wireless clients are on the same subnet.
- The router is a Linksys WRT-350N
- AP isolation is disabled
- uPnP is enabled on the router

Does anyone have any clue how to fix this?

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.)

When I download that zip file from under "Install the Bluetooth driver:" it has so many files to choose from.... I don't know what to do?

I've also found out that I need to disable "boot from network" or "boot from lan" in bios to get rid of this unkown device issue?

Well it might be a good idea to look at the following tutorial:

Use the link in Step 7

Also I tend to find this tool useful:

Right click on each result in the list for more options.

Edit: On my machine a similarly named device appears to be a webcam.

In the list USB Composite Device doesn't mean much but matching the ID seems to indicate that it's the webcam.

Does anyone know what driver the Digital Microphone Device would use on the M920q Tiny.  I have installed a Windows 10 1809 image using MDT with the SCCM driver pack but Device Manager shows Digital Microphone Device not installed and I can't find a driver. Anyone else had an issue with this or know which driver, the driver on Lenovo site errors on install. Many thanks

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?

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

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.

The drivers can become corrupted, which is why a re-install will fix the problems.As to how they get corrupted, that's anyone's guess...
