Realtek RTL8168D/8111D PCI-E Gigabit Ethernet NIC Won't Detect Ethernet Cable?
Aug 8, 2012
I am having a problem with my Realtek RTL8168D/8111D PCI-E Gigabit Ethernet NIC. It is not detecting my ethernet cable, and thus leaving me without internet on my desktop, after i updated its driver. The cable is not the problem as I have tested the cable with my laptop. I tried rolling back drivers, doing system restore and removing drivers with driversweeper and letting windows install the drivers again. However, none of these worked for me. I doubt the NIC is faulty as it was working before i updated the drivers. I am using windows 7 home premium 64-bit.

I recently said to hell with wireless and wired my apartment with Cat6. My desktop computer next to the router is running fine at 1Gbps. My media center one room over is only running at 100Mbps, and I cannot figure out why.
The motherboard has a Realtek RTL8168D . I have green ethernet enabled... could that be it? Auto disable gigabit is disabled. I tried changing speed & duplex from Auto to 1Gbps, and that didn't change anything. The latest driver is installed. Their ethernet diagnostic utility shows the link speed at 100.

I recently moved into the dorms of my college and tried connecting my laptop to the internet using an ethernet cable. It worked, so I decided to try and play Xbox Live through the use of the ethernet cable and it did not work. After messing around with it and failing to get it to work for my Xbox 360, the ethernet decided to quit working for my computer as well. (To try and get my Xbox to connect to the internet with the ethernet cord, I tried network bridging by bridging the ethernet connection with the wireless connection, then unplugging the ethernet cable from the wall so as to connect it from my laptop to Xbox 360. This didn't work so I just deleted the bridge. This is when the problem started happening as the local connection stopped appearing.) I am able to plug it in and see that in the Network and Sharing Center, however, it shows up as being unplugged. After a couple seconds though, it disappears. If I click on it fast enough, it shows up with an Error Code 45 after looking at the properties. I have tried typing in ipconnfig /all and the ethernet connection doesn't show up there either.

I'm having an issue with my network adapter. It's not detecting the Ethernet cable, thus not able to connect to my home network. The trouble shooter (Windows 7 home 64) says it canning detect the cord. But the cable works fine on my other computer. The network adapter is a Nvdia nforce networking controller. All the drivers are up to date. The computer was completely formatted so it's a blank slate

Today when I came home from school, I opened my computer like everyday. Suddenly I noticed that my Internet isn't working. It said I need to connect the Ethernet Cable. Well, my cable sometimes gets loose, so I tried to tighten it up a bit but that didn't work. I tried the cable with another computer and it works fine. I checked device manager and everything should be fine there.computer is running Windows 7 Professional.Drivers are up to date, and nothing changed in the computer since yesterday when it was still working. Could it be just that the Ethernet cable port suddenly broke down? I also tried another cable, and that didn't work either. I restored the system to previous saved point.

i have a DSL connection which is established using a dial-up (PPPoE) modem. I recently bought a wifi router, and I found that when I plug the cable to one of the LAN ports and the laptop, it seems as if it wasn't connected at all (not detected on either side).I tried to format the system running on XP and I installed windows 7 but the problem persists.The only thing I can think of right now is using a crossover cable, but I somehow doubt that it should work since I tried plugging the router to my netbook (using a normal cable) and it worked like a charm. But maybe the fact that it's a quite old laptop (PB MV51-101) has something to do?

I tried 3 cables, and even one of them was new. So im sure the problem isn't the cables. For some reason, whenever I connect a ehternet cable to my computer, I cannot seem to get internet connection through it. Some days ago I installed this Wireless Lan device from a CD, that came with a sort of antenne I had to put on my computer. It works great, BUT its slow. Thats why i would like to go on internet with cable again. I remember one day to another that my computer didn't detect the cables anymore, what could be the problem?

My roommate and I are trying to set up the internet, but my computer won't detect the Ethernet Cable. Whenever I go to Network and Sharing Center and try connecting to the internet, the computer simply says "Windows did not detect any networking hardware", even though the light is clearly on and should be working. The cable is also new so it should be fine. I've also been looking around on the internet a bit, and in trying to fix the problem it looks like some of my Services are turned off, which seems to be causing the problem. However, whenever I try and turn them on, I get an error message saying "The dependency service or group failed to start".

Is there a difference in an ethernet cable and an Ethernet networking cable? I have an Ethernet cable and a 6 port splitter I am trying to connect. I have 4 ports in the router that are in use. When I connect them to the splitter nothing s working.

I have an Ethernet Loopback Plug (4 Pairs) made and trying to test the Gigabit Interface on a 3845 Router with a fail result. The interface will show up/up only if I set the interface to 100M/Full Duplex when I plug-in the Ethernet Loopback Plug (4 Pairs). I don't see this Gigabit Interface @ 3845 router has any option to set it to internal or external loopback.

I have a Dell XPS M1530 with Vista 32 bit. When i plug in a cable i get nothing, no error, and the comp does not recognize that a cable has been plugged in. I think that this started after my Hard drive failed and Dell replaced it but i'm not positive. No errors (? or !) in Device Manager and I can't find the Marvell 88E80XX 10/100 Ethernet Controller in device manager. I have attempted to Reinstall the drivers. The wireless is still working. I have one Light to the right of the port that is on all the time solid but no flashing with the cable in or out.

I currently have 2 PCs that are directly connected to each other via a 1Gbs Cat6 connection.I don't currently have a 1Gbs router so what I am doing right now is unhooking this connection and reconnecting both machines to my router when I need internet access. I have ordered some USB Wi-Fi adapters so I can have both machines access the internet that way whilst still use FTP between them on the 1Gbs line.If I were to scrap that idea and get a 1Gbs hub, connect both PCs straight into that, and then also connect the hub to my 100mbits router, would the 2 computers be able to communicate with each other at 1Gbs and then talk to the router at 100mbits, or would the whole network run at 100mbits.I don't really want to have to shell out on a 1Gbs router as I don't need anything else on the network to run at that speed.

So my old router needed replacement and my dad bought a Netgear gigabit ethernet switch instead of a router. It said that it gets 1Gbps when I look inside the local area connection speed. The problem was we tried to use it like a router but only 2 computers could connect to the internet at one time but it was indeed noticeably faster when it came to video streaming speed. We since returned it and bought a Netgear N600 router that says the speed is 300mbps but like my old router it shows the speed is actually 100mbps and the streaming is good for the most part but every now and then slows down. Would using the ethernet switch with our new router work with streaming speeds and connection stability and of course let more computers connect and also use the routers wireless.

I have the following problem. I bought two TP-LINK TG-3269 gigabit cards, placed them in two computers and connected them directly. On my Ubuntu system I used iperf tool and measured only 95 Mbit/s. It wont go any faster, I tried many times with different settings.
The indicator lamp shows 1000 Mbit/s.

But I currently have a Linksys E3200 I bought in a moment of weakness after an evening of being pissed off at bricking my old WRT610N. (soft bricked, but I'm beyond screwing with it)
There's nothing *wrong* with it, but I am interested in something that either comes preinstalled with DD-WRT, or is well supported (ie easy to install on) by DD-WRT. I plan on selling the E3200 once I find something to replace it.
My requirements:
-Gigabit
-5 GHz (I have a file server/HTPC; I don't want to be limited to gigabit ethernet)
-$150 or less (I know $150 is high, but I figure I'll get close to that for the E3200)

I am moving into an apartment thereafter. I have an HTPC in use, a personal computer for gaming/processing, and my fiancee has an Apple Macbook Pro that she uses quite often. I have an HDHomeRun Dual (2 tuners) for streaming OTA/QSM cable over the network (the HDHomeRun plugs into the network, not a computer). I also have a TV and Blu-Ray player that have ethernet ports.
Currently I use Verizon Fios and their Actiontec MI424WR router, which to my knowledge has gigabet ethernet. When I move I will probably be saddled with Comcast Xfinity Internet, which will supply a cable modem if I want, but no router. The only router I currently own is a Zyxel NBG-419N, which has only 100/10 ethernet ports. My current computers all have gigabit ethernet. For the home theatre components and my HTPC, I plan to pick up a network switch with gigabit ethernet. So my questions are:
1. If I use the Zyxel and the Comcast cable modem, would I be throttling my network speed at the router? I would hate to choke my speed just because one component does not have gigabit ethernet.
2. If I were to upgrade to, say, an Asus RT-N56U, would that make a huge difference on network browsing and throughput speeds?
3. Finally, what kind of cable is needed to maximize discernible speed increase? Cat5, Cat5e, or Cat6?

how the ASR1000s are being setup.I am looking at ASR1000s as part of network refresh and was looking at RJ-45 based Gigabit Ethernet ports compatible with the ASR1000s SPA-5X1GE-V2 seems to be an option but they are all SFPs. Are there any options for RJ-45 ones on ASR1000s?
There is an option for the 2 port where one can mix and match SFPs and RJ45 but I was looking for something which is RJ45 only.Are there any options for them available.I know I could get something with FastEthernet type but was looking for the GigabitEthernet type.

When I plug my ethernet cord into my Dell XPS laptop, Windows doesn't detect that I have a connection. I've tried another cord and it works (it's too short to use instead) and my roommate has tried my cord and it works fine on his computer.I've tried diagnosing the problem, disabling and enabling the Local Area Connection, but nothing seems to work.

I have a two computer network. Here are the network adapter details of the two computers.
-Realtek RTL8111E Gigabit Ethernet Controller
-Broadcom NetXtreme Gigabit Ethernet
I'm using a CAT5e cable. But it gives only a 10 MB/s file sharing speed. What is the reason for this? (In both the computers under "Local Area Connection Status" it shows 100 Mbps for the speed)

Purchased and configured 2951 router based on Telco specs that required T3/DS3 card with coax connection for MPLS. When telco showed up to install DS3 they handed me a UTP copper connection.... Can I use one of the Gigabit ethernet connections on the 2951 as my MPLS interface into the provider's cloud?

We have a Cisco 7206 VXR Router with NPE-G2. As everybody aware that, It has got 3 x Gigabit Ethernet Ports on this. We would like to add Two more Copper Gigabit Ethernet Interfaces. The Configurator does not show any options to add that.Now we have a doubt that, Does this 7206 VXR support how many Copper Gigabit Ethernet Interface ?. There is no clear answer available in the Data Sheets.

So lately my computer's wireless network has started to get really bad, we have 100mbit, and it only gets about 0.3. This seems to be an issue with the range, or something, since if i move the computer right next to the router, it runs at about 50-60mbit. Now a few days ago i decided to get an ethernet cable to try and solve the issue, but my computer doesn't detect a LAN connection, only the wireless one ( atleast it doesnt show up among the other connections). Some weeks ago the wireless connection worked nicely, but now suddenly it doesnt anymore. Currently i'm typing this from an old mac computer, since my internet doesn't work at all on my pc.
