A network cable is unplugged

I've been trying to set up a wireless network at home using the Netgear RangeMax dual band Wireless-N Router. After inserting the setup CD and began running the network wizard I received the message ''Unable to connect, a network cable is unplugged''. As I looked in my network connections I noticed that the ''Realtek RTL8139/810x Family Fast Ethernet Nic network cable is unplugged''. I've already replaced my network adapter with ''Nextgear gigabit PCI adapter 10/100/1000 GA311'' with no luck. I've also replaced my cable 5 times. Now I also have 7 local area connections with the ''Realtek RTL8169/8110 Family Gigabit Ethernet connection'' and 9 local area connections with the ''Realtek RTL8139/810x Family Fast Ethernet Nic''. I've read so forums and some suggest deleting the connections from my registry, but I'm not comfortable with deleting items from there. Thanks in advance for any help you can give me.

OK, in order to solve this problem, I will need more information:

1) What is your operating system (i.e. Windows XP? Windows Vista?)

2) Is this a laptop or a desktop computer?

3) If it is a laptop, is there a switch on the case that turns on and off the wireless ability? Check your user manual - it might be as simple as turning on the wireless switch.

4) If it is a desktop, what kind of wireless adapter did you install?

I'll be able to help more when I get this information. In the meantime, here are a few things you can do:

First of all, you need to delete all of the duplicate connections from Network Connections. They won't really hurt, but they're not helping either. To delete them, just right-click on them one at a time and choose "delete."

Next, you need to understand what the message "a network cable is unplugged" refers to: this has nothing to do with wireless. If there is no actual hard-wire cable connected to your computer, the port (that's the opening that you plug a network cable into) will tell Windows that it is empty. This results in the message "a network cable is unplugged." You can ignore it, or - if you plan to use this computer with a wireless connection only - you can right-click on the connection in Network Connections and choose "disable." This stops the message from appearing, and can be reversed (enable) at any time.

I look forward to hearing from you.

I have forgot my router password, and can not add a wireless item


If you have forgotten your router password, the easiest thing to do is to reset your router to the factory default settings.To restore the router configuration to factory defaults, hold the reset button on the unit for 30 seconds.
Try this also:- u can recover it by simply connecting one of ur computer with the help of cable to router port 1, then open the browser and enter 192.168.1.1 in address bar .username ....... (blank)
password : admin
go to wireless ...then goto wireless security ... and there is ur security WPA key ...password.. make a not of it and try to connect it...
it would work without changing any personal settings...
Best luck try it out ..

Hate to sound dumb, but have a new Soney lap top and can not find place to plug in telephone cable so that I can go on line. Have several other computers and each has places to plug in the wall to the...


Does it have a modem? I'm thinking you probably do not have a modem ... dial ups are generally a thing of the past. Fewer and fewer computers come with modems built in, deferring to a network (NIC) connection or wireless connection. A NIC connection looks like a telephone connection but the NIC (Network Interface Card) has 8 conductors while a modem would have only 4 or 6. Warning, NEVER plug a NIC into a telephone outlet. A NIC operates at a very low voltage ... if the phone rings while your computer is plugged in ... there will be a puff of smoke as 60 volts enter your computer ... guess what is next ...

If you have several computers and are presently taking turns plugging the computers in for a dial up ... I would suggest to you it it time for a wire or wireless network in your home. That way you can have all of your computers share your conenction ... though I will tell you in advance, your connection speed will be severly hampered due to the current speed limit of about 56,000. Cable, fIOS or DSL lines operate in the millions of bits. If you have this type connection ... you still need a modem ... just add a router to build your network, but you dont need individual computer modems.

If you are interested in building a network ... you will need a wire/wireless router and a modem. You would control the modem from a computer and you would install connection sharing from within that computer. This will allow the networked computers to share the connection you have. It similar to a client - server network in that one computer controls and then shares the conneciton with other computers. ... still it would be a peer top peer network (no computer is superior to any other computer)

Im starting to ramble ... if you are interested in a network ... research the topic and if you get stuck, post a question. There are lots of network "expert" volunteers who roam these virtual hallways.

Thanks for your interest in FixYa.com.

One of two HP laptops connects to network but quit on Internet


did you play with your wireless router settings..?? When it is shown as unidentified, you have most probably set as hide network name . other computers may show up the name if you have saved the network settings on them at least once.

Drivers are fine as they are able to detect the network.

HP laptop shows full internet signal, wont let me connect


First, the "Network Cable Is Unplugged" - don't worry about that. That is just informing you that your WIRED connection is unplugged, which is fine because you are using wireless.

Now the actual issue of no internet...first try by unplugging your internet modem for 20 seconds, and plugging it back in. Next do the same with your wireless router. At this point your computer will disconnect form the wireless network and you may need to reconnect it. After the reconnect see if you still have the same issue, but chances are it should be fixed :-)

If that does not work let me know and we can further troubleshoot the issue!

Connection Cable Unplugged Realtek RTL8139/810x


I got the same NIC (Network Interface Card) a few weeks ago, and my connection has been dropping out as well. I've tried different versions of drivers, but without success. I was playing around with the NIC's settings, and this is how I fixed the problem.


Right click on "My Computer"
select "Properties" from the list
select the tab named "Hardware"
click on "Device Manager"
expand the tree item named "Network Adapters"
right click on the Realtek RTL8139 and select "Properties" from the list
go to the "Advanced" tab
Select "Link Speed & Duplex Mode"
On the drop-down menu to the right, select "10M Full mode"
Click "Ok"
close out of Device Manager and My Computer properties.

The problem should be solved. The only disadvantage to this is that speeds on a local network will be slow on this computer, or if you're lucky enough to have a +10 meg line straight to your house.

Hope I helped,
Daniel

Do you have your wireless network locked down with a password? It should be just like setting up a wireless network, you may have to enter the info in manually in the TV to make it work properly. I'm trying to get my link stick but they are sold out everywhere. Once I get it I can help you guys.

Linksys wireless-g


It has nothing to do with the brands. I do have different peripherals of different brands and they work well.

Maybe your son's laptop is more recent than yours. When you connect the wireless adapter to your laptop, does it detect the wireless network? I remember having a similar problem on vacation. At the hotel, I could'nt connect to the wireless network. The tech support told me to adjust some settings on my laptop. He said to go to the Network connexions, right-click on the wireless connection and selection Properties. Click on Configure...And select the Advanced button. Then on the list select Power on saving Mode. Other than Max power save mode.
