Network / Sharing :: Windows 8.1 - Operating System Doesn't Detect Network Cable
Dec 15, 2013
I re-installed Windows 8 yesterday evening (thought it would be quicker than to cleanup and fix my old install) and then directly upgraded it to Windows 8.1. The problem I am experiencing is quite weird: The Operating System doesn't detect the network cable.
With that being said, do not jump straight to the "Did you turn it on and off again" questions. Here is what I have done so far:
Hardware-Side: Cross-check the cable with another computer --> Working fineCross-check the wall plug with another computer --> Working fineTest the connection with the BIOS's connection diagnostic utility --> Link detected
Software-Side: Checking if Windows was up to date --> Nothing to updateUpdating the motherboard's BIOS --> Not betterUpdating the LAN's drivers with the ones I found on the manufacturer's website --> Not better
I am wondering what is wrong with my installation. It was working A1 a few days ago, except for the issues I re-installed the operating system for.

The cable works on a different computer, the computer gets wireless fine (typing to you from it) but will not read an ethernet cable. The motherboard manual (built the PC myself from components) says an LED should light-up if an ethernet cable is connected, no such LED appears when I connect the cable.

I went to a PC-Shop that fixed it by putting another driver on the PC.But now I have a new PC and after 6 months without any problems Windows suddenly decides there is no ethernet cable plugged in the PC. I've googled for hours and hours trying diffrent things, but nothing seems to work . The cable itself is fine because when I plug it into my laptop it works fine. I've updated my driver, deleted it and try to reinstall, which also failed. I tried out some commands through CMD, which also failed.
It is a custom-build PC with a Asus Z87-A motherboard (in-case that's necessary to know) and the driver that's installed is Realtek PCIe GBE Family Controller. OS: Windows 8.1.

At random, Windows would refuse to shut down, although it would cancel out the display. Hitting the power button it would bring the PC back to life in a state half in shutdown and half alive. Upon restart, Windows will refuse to detect my LAN driver. It wouldn't even show up on the device manager (not even as an unknown device).
I have Gigabyte G1 Assassin motherboard with BigFoot Network LAN card. To make the LAN work again, I have to delete the Big Killer Network software from my PC and re-install it again. But after two days, Windows will do the same thing all over again.

I had a hard drive crash the other week and I got a new one and went on and upgraded to windows 8.1 64bit. Well I had a hard time getting it to work correctly but now it seems to start up fine with no BSOD.
My problem I'm having now, is that my internet will not work on it, unless I plug in a wireless for it.
My mobo is rather old, (msi k9a2 platinum) and it uses a Realtek PCIe GBE Family Controller on it. I first tried to go and upgrade the drivers. It said I had the newest. Though upon reading online I see that they have upgraded the driver for the Realtek to the 8.26.218.2014 driver on 2/18/2014. Well I uninstall my old driver, restart the computer then install the new one from the Realtek website. Then do a restart and still nothing.
It looks like the router is getting pinged or something as it will start flashing in the bottom right with the triangle with the ! in it, about three times then go back to the x in the red circle. In the device Manager the realtek pcie gbe family controller doesn't have the yellow triangle with the ! in it showing that something is wrong. But it's not even reading the ethernet cable is plugged in. I tried detecting the problem and that is all it says is to plug the cable in.
I restarted the computer again and noticed that the number showed up on my router that the computer was connected. When the computer was starting windows with the blue windows logo with the balls circling at the bottom, about half way through the router dropped the number and it doesn't come back up after I unlock the computer.
So I followed the sticky and got the cmd prompt and this is what it is showing...

Since yesterday the internet began to act unsoundly (through WiFi). As in I never had this problem before. There were periods where it was fast enough to play some online games, watch Youtube no problem, and then it would shut off randomly. So since yesterday I have been restarting the modem with only very short term resolutions to the issue.
I accessed the modem through my web browser and it says the connection is always working fine. Despite that, I called my ISP and they claimed there was an issue, and forwarded it to Deutsche Telekom. Since then I did some experimenting and plugged my computer into the modem with the ethernet cable.
Boom. No problem whatsoever. It's been top speed and reliable.
I downloaded and installed updates for Windows today. There are 18 optional ones that I did not download yet, but I did download and install the important ones no problem. I checked the network adapters and they all state "The best driver for your software is already installed."

I was happily using file history, it was backing up to my G partition, which is located on my second hard drive (both drives are internal)but now I get error message:
I think the problem is that this partition got added to my user, that's what the network path shows:
How do I get it out of my user, and back on a normal path?

my network connection on my laptop. I recently moved up to my college and am now on their network. However, I didn't have this problem at first. But recently if I go to my network connections, there is always a wired connection listed named "Unidentified Network" which has "Limited" access. The problem here is that I am not connected to any wired networks. There is no cable plugged into my computer so I don't understand how this is possible. The only thing I have installed recently is Virtualbox, just in case that could affect it.

I have been having issues with sharing my internet connection via an ethernet cable. I read online that there is the ability to 'share' your internet connection. I have learned how to do this, but it doesnt work for me. I tried connecting my laptop. I went through everything and I was able to get the connection (it showed the LAN connectivity icon) however, there was the little yellow triangle next to it. I waited but it won't connect. What I am trying to do with this is be able to play multiplayer on computer games with other computers on my LAN. I also tried to connect my XBox 360 with this, but it doesnt have an internet connection.
Things to keep in mind The only way I could get a good internet service was through my cell phone service provider, so I get my internet connection through my phone via USB tethering
All of the computers I am trying this on have Windows 8 Pro, except for one

I'm having problems with my Asus NV56VM laptop (windows 8). Whenever I try to use an ethernet cable to access internet I either get a SSL-error, the website doesn't load at all or it loads VERY slowly and not the whole website (it says that I have internet acces and that it's not limited). Wireless works fine though.
I've also tested playing some games (ex Call of duty) and it works fine for like five minutes and then I get an error message saying something about packages didn't receive correctly. So I'm guessing it have to do with not all information is transferred when I use ethernet.
According to the Device Manager I use "Qualcomm Atheros AR8161 PCI-E Gigabit Ethernet Controller (NDIS 6.30)" and the drivers is up to date.
Things I've tried:
Using a different ethernet cable.
Testing it on a different network (at my friends house)
Reinstalling drivers (both from Asus website and from Qualcomm's).
Disable wireless
Empty cache/cookies
Restarting computer/router/modem
Turning off firewall
Searching for virus (didn't find any)
Ipconfig /release /renew
Tested it on different browsers (I also affects games though)
Formatting my laptop
SSL and TSL is enable

Just curious ... do PC-to-PC file transfers count towards cable Internet service usage? For instance, if I move 10 GB of data from one PC to another in my Homegroup, is that 10 GB counted as part of the 100GB+ of cable data that I've used?

My PC is unable to detect 5Ghz band where rest of the devices at my home are detecting both the bands.
I have recently bought D-Link dual band router and installed at home. Router is working absolutely fine because I could see my other laptop and Ipad are able to detect both the bands. So that says there no problem with the router configuration. Also the router which I have bought is recently released, so there are no new updates are released yet.
As per the installation guide, 802.11a supports 5Ghz and IEEE 802 11b/g/n supports 2.4 Ghz.
My PC details :
Model : Sony SVF14A190X (an year old laptop)
Operating System : Windows 8.1 Pro, 64 Bit
Network Adaptor drivers: BCM43142 Wireless Network Adapter
Router Details: D-Link DIR-850L VER A.1 wireless AC1200 Dual Band Gigabit Cloud Router.
The network adaptor which my laptop supports IEEE 802 11b/g/n..i.e.2.4 Ghz. I tried installing the Network Adapter drivers in compatibility mode, but that doesn't fix the issue.
When I checked in Command prompt, it says : Radio Types Supported : 802.11n 802.11g 802.11b.
How should I upgarde network drivers to : 802.11n 802.11a 802.11g 802.11b

I generally create a hosted network with this command:
netsh wlan set hostednetwork mode=allow ssid=foo key=foo
netsh wlan start hostednetwork
However, after running that script and restarting, it is unable to set the IP address (See screenshot).
Also, there are many logs in Event Viewer which says this: The DHCP allocator has disabled itself on IP address 169.254.212.34, since the IP address is outside the 192.168.137.0/255.255.255.0 scope from which addresses are being allocated to DHCP clients. To enable the DHCP allocator on this IP address, change the scope to include the IP address, or change the IP address to fall within the scope.
I need to get this hosted network up and running!

We have a nice signal from the router until about the same time each day. Only cable tv modem is available. Evidently the country neighbors do lots of internet during the afternoon.
Is there a way to boost the signal coming down the cable line ? The cable tv company has installed new cables from the pole into the house. We have installed all new cables in the house.
All of the boosters I've seen are for after the wireless signal gets to the cable modem.

Randomly, my wifi disconnects many times a day (Limitted conectivity or ), sometimes every 5 minutes. I solve the problem temporarly by:
1.)Running the Troubleshoot of the wifi connection, and it resets the adapter automatically( and at the end of the troubleshotting it says: "WiFi doesnt Have a valid IP configuration, or sometimes The default gateway is not available")
2.)Sometimes the Troubleshooter cant reset the adapter, and I have to do it manually.
By resetting the adapter, the problem is solved only temporarily, because I have to do that mayby 20 times a day, sometimes more, sometimes less.
I use Windows 8 on Asus K55 VJ , Intel Centrino 2230 adapter with up to date driver.

I recently got windows 8 and have found it to be rather volatile. I use WiFi in my house on my desktop Intel PC and my computer strangely sometimes works to get to the internet and sometimes it doesn't coming up with connection limited and after troubleshooting it "doesn't have a valid ip configuration". Ive tried the netsh winsock and the ip reset commands in command prompt (admin) and nothing happens i'm really at a loss. According to some people A/V programs can mess stuff up so i uninstalled them.

I have a new desktop with Windows 8 that replaces a Windows XP system. I plugged in the existing Ethernet cable to my router, but I cannot contact my (ancient) Windows 95 system in my local network. My XP system did so just fine. What can I do to get my new system to talk to the old 95 system?

I'm not much of a VM expert. I have a couple of win7 systems running a WinXP VM that I installed manually, in all those cases, the virtual network has always just booted up and worked. Under Windows 8 Pro-RTM, I did a XP VM that I loaded myself (versus an XP mode) and it loads the virtual network adapter but it reports that the cable is unplugged
I'm not clear on what this means. Obviously, it's a VM so there is no cable to plug in. I'm guessing I'm suppose to match that Virtual Nic to the regular (aka Host's) NIC but I'm not see any options to do so.
On the same system I run windows 7 Ult and a XP install and the network loads up on boot.

Recently I have been intermittently getting disconnected from the internet while gaming / streaming. If I ran the troubleshooter, the error that I got was "Default gateway not available". Resetting my router/modem and restarting the PC every time it happened seemed to resolve this for a while. and is now accompanied by another error saying that "Ethernet" doesn't have a valid IP configuration. This is much more frequent now, every 10-20 minutes or so. I am on wired internet coming from the combo router/modem from my ISP/Cable co.
Attached is my ipconfig /all while working and after the error.

My fully updated Windows 8.1 notebook suddenly will not show any wifi connections when I click on the icon in the system tray (it shows "No Connections are Available", although it is connected, and I can surf and browse normally).
To connect to a new network, I have to manually enter the details of the network, and then it connects. This is something new, since previously it would show all the available networks, and allow me to make a selection (which is normal). What setting could have flipped do enable the above situation?

My Internet is fine. I can connect with my iPhone, and with Ubuntu OS.
It's just the button in the bottom right hand corner (the wireless signal bars) doesn't do anything after I click it on my windows laptop.. It happens every so often disallowing me from connecting to the Internet in times when I need it.
