Dell :: Vostro 2520 - Realtek Network Controller Not Found
Mar 1, 2013
I am facing this trouble since i purchased this laptop i have a Dell vostro 2520 running on windows 8 pro X64, so the problem is that whenever i try to install drivers for Ethernet which i downloaded from the drivers and download section of this website it gives me an error "Realtek network controller was not found If in deep sleep mode please plug in the cable" now the thing is that it cannot be a problem in my windows as i was running on windows til few days ago, I got the same problem in windows 7 as well,
I have searched everywhere and i have tried almost every solution i got but to no avail the problem still persist and i cannot use LAN for Internet or file transfers,
P.S:- I looked for the adapter under the "control panel system and security system device manager Network adapters" But didn't found anything there saying Ethernet or something like that.
I am uploading the screenshots of the problem i am facing.

Dell Inspiron laptop n4110-6 gb RAM- 575 gb HD- intel i-5 processor 1333mhz. Win 7 -64 bit
everything was fine until yesterday...started up laptop and noticed the network connection icon in my task bar hd the "red-x" through it...i knew something was up cuz i had ethernet hardline in to my machine. after I had inspected every possible home netwrok issue...i noticed it was more pc related.now i go to my device manager to check my network adapters..... there are NONE listed...i go to "View" to find that unhide all devices and note there are only wireless drivers in this device and NOT the typical "realtek-8111E" controller that SHOULD be listed.
So far...i have done these steps
1) ensured BIOS (my cmos is phoenix tianos build) lan settings are correct- done
2) Removed RAM from slots
3) Removed Cmos Battery
4) waited for 15 minutes.it is still not working ....a i even tried a clean install of win 7 and that doesnt work?

Everything was working fine, I was able to make everything work fine. Then yesterday morning I started up my computer and it was not connected to the internet. My ethernet was plugged in and everything was as it should be. I went in to device manager and noticed that my realtek network controller was not in the device list under network adapters. I then tried to reinstall my LAN drivers from ASUS (my motherboard) which is how I got it to work in the first place. However, this time when it "finishes" installing an error pops up and says "The realtek Network Controller was not found. If deep sleep mode is enabled Please plug the cable."

I have 10 Vostro 460s, the network cards are not being found on startup. You have to reboot the systems 3-4 times to get Windows to find the Network cards. All drivers are up to date. This may be related to a Windows update, since the machine were fine for a month or so until an Update came out.

I've bought a new Dell N5050, first it was on Ubuntu, then I formatted my disk and now working on Windows 7. Due to that, I've lost many drivers specially for wireless and network. I've downloaded many from here, but I'm still unable to find these 2. In other words, I can't connect to the wireless connection unless I use the Ethernet cable.
here is an image, it's french.
by the way, I've downloaded a lot of drivers, I wonder why I still got these two missing. ( did I download wrong ones?)

i just reinstalled windows on my laptop and i figured i could just download drivers from the dell website. after following the installation order specified on the website.. installing first the NSS and then the chipset, etc.. I realized there wasn't a driver for the NIC on the website. i also noticed that the steps didn't include a step for ethernet drivers, so i replaced the NIC step with installing the broadcom integrated controller. unfortunately, after completing the rest of the installation steps, my Network Controller driver is still not installed (looking in the device manager), a hardwire connection through the ethernet cable gives me "limited or no connectivity" and there is no wireless capability whatsoever.

On receiving my new dell vostro 3550, I reinstalled the windows 7 cd that came with the computer.
Before I did, I had internet connection, now I don't.
It says it finds no device. All i did was install windows. What else do I need to do for it to recognise the devices are on the system?

I'm still having problems (as seen in 'Network Controller Not Found (Clueless!)) and have a quick query.I'm trying to locate a specific driver and so far have exhausted my search, can I get anything from the Hardware Id from the Unknown Network Controller?

I've got a Philips MT1800, Intel Core 2 Duo package. My network adapters are recognised (1394 Net Adapter, Intel Pro/1000 PM Network Connection), but in unknown Devices the 'Network Controller' drivers are not found (there was a Ralink RT2500 slot before, I'm assuming this is the missing driver??). EVEREST Home Edition recognises a Ralink RT2500 802.11g Wireless Network Adapter (PCI), and my PC finds new hardware on reboot, but it cannot find drivers at all. I've tried a few methods, such as Driver Detective etc. but don't have the original restore CD any more, so don't want to tamper with any other "out of date" drivers. I am not in a situation where I can order a restore CD, so I'm hesitant to System Restore in case something else becomes unresolvable.

we're running some HP ProCurve 2520's (24 port PoE for desktops/phones) and 2510's for our server racks. The CPU's are a bit weak from what we can tell and sometimes end up with issues on them. The specs on the EAS series look like a decent jump compared to the older HP's. However I've never worked with these ever.
My other option is to go back to Cisco. However to make it fit our budget, we have to dump gig switches for 10/100 + PoE. Which isn't really a major issue on the desktop switches. We'll naturally put gig versions on the server racks. I like our ProCurves, however they cause issues from time to time.
I've also considered going back to Adtran, however I haven't kept up with what they have to offer. I'm tempted to play it safe and go the Cisco route. We're using ASA5510's active/passive for routing/firewall (gig versions).

My computer started shutting off and not turning on. I had installed new parts a while ago and so I switched the new parts with the old ones (power supply and Graphics card) and it worked again. But i couldnt connect to the internet and i did a diagnoses and it said adapter not found or correctly installed or something like that. I couldnt find the adapter either. I was going to download the network adapter driver from the dell website on to a thumb drive and install in onto my desktop but i do not know which one to download.

Today I replaced my motherboard to fix the graphics card issue on my Vostro 1400. After installing the motherboard I installed the driver's from Dell's site for the networking card.
I get an error stating device driver/software was not successfully installed. I tried a restore point, that didn't work either. I tried the original driver disc that came with the laptop - same problem.
In device manager it is showing: broadcom netlink adapter fast ethernet #2 - does that mean it thinks I have more than one network card? I'm not sure what to do next. I can't access any wireless from that laptop, not even from a hard wire.
I'm running Windows 7 32 bit.

I can't connect to the internet. I'm currently using a USB internet, but the problem still exists. So it's not working with either cable or USB internet. It just won't connect. I've thought for a long time that there is probably something wrong with my network card, but I've run some tests that I saw on the internet, and it appears as if the network card is fine. I've also thought that there might have been a program or something that I installed that could have caused this problem, but I can't find the problem. When I go to the device manager, I can find one network card called: "Realtek PCIe GBE Family Controller". I've tried to reinstall the card, but it doesn't work. I can't find any software on the internet for this card either.

I have a DELL Latitude 630 running Windows Vista. I checked into a hotel and just cannot find the wifi network on this laptop..IT is a named network and yet all i see is an unnamed network on my list of networks found. My blackberry device can easily locate the network..but the laptop simply refuses. I have tried restarting, playing around with the advanced propoerties of the wifi adapter but all in vain. I can use the office wifi ont he same laptop without any issue..but not in my hotel.

My Dell XPS83000 does not find the network card when the PC is started in a "cold" condition. I have to restart the PC 3 - 6 times before the card is found. When the PC is "warm" the card is found without any problem.

Ive just downloaded wireshark just to mess around and ive noticed that even when ive got nothing open its still capturing packets. It gives me a choice of interfaces i want to choose to monitor and i would of thought it be "Realtek PCIe Family Controller" as this is normally the default one (im using wireless) but its saying no packets are being captured from this interface its the "Microsoft" Interface thats capturing the packets. Ive attached a screenshot, i know this isnt nothing bad but was just wondering 1) why isnt my Realtek PCIe interface capturing anything (even when i have youtube open it doesnt capture anything) and 2) why is Microsoft capturing packets? what is this microsoft interface and why is it capturing packets when nothing is open.

Having just solved the missing network controller on my Dell Inspiron laptop I thought I would try the old Dell dimension 455-0 desktop I have. It too is missing the network controller, I can access web through wireless usb but not though cable or wireless. I have the disc but I can't install from it as I get message saying it is outdated. Tried Intel but the download ends prematurely and so doesnt work.

I have tried everything to install my broadcom driver with no luck . My chipset driver has two identicle drivers in device manager. Are they supposed to be there twice? I have downloaded it and it looks like it installs but it never makes it to device manager? It will not install directly fron device manager. It is the only driver that will not install. I already know the chipset driver goes first.

I recently bought a new Dell Inspiron 7600 pc running on windows 7 home premium and to enable access to our wireless internet I installed a Realtek 8185 wireless pci adaptor. It has worked fine (although not without the occasional blip) but recently it has stopped working. I could connect to our wireless network but connection came with a small exclamation mark on the wireless connection icon in the system tray. I tried reinstalling the most up to date drivers I could find on the realtek download website and this has removed the problem of the exclamation mark with the wireless connection claiming it now has internet access. However the internet is now so slow (vastly slower than before these problems began) I get timed out errors whenever I try to access any web pages. I have ruled out the router being an issue as my two housemates' computers are working just fine.
