Laptop Ethernet port not working

June 4, 2012 at 03:58:54
Specs: winxpsp2, 1.79ghz/368mhz

I am looking at a laptop that doesn't want to connect to the net via the ethernet port. IT shows up as connected when a cable is inserted and in device manager everything is fine. not sure what to try next to get it connected. Could this computer be infected and the infection block a proper connection?

Just downloaded the driver from http://support.lenovo.com/en_US/det... but still can't connect. Hmmm with check if there is any dust in the post. I also tried to install a wireless card but that got blocked too. I am using that word but i don't know whats happening. The icon in the tray says that it is connecting but then it says 'wireless network connection2. windows is unable to connect to the selected network. the network may no longer be in rage. please refresh the list of available networks, and try to connect again'. which i do with not results...well the same thing happens...hmmm maybe there is some block of some kind like a virus

For the wireless connection, you need your own wireless router, that must be configured correctly, to get a connection to it.

Anyway, when you are connected by wire, open a command prompt (Start / Run / cmd) and type in:
ipconfig /all

Post the result for review.

Hi thanks got the driver on a cd and was trying to connect to my router. Can't do anything right now as i downloaded avast onto my linux machine and installed it via a usb stick. The cd drive is also not working on this laptop so . Anyway a scan is happening. In the system and now a boot scan. It found a worm (JS Agent-10(trj) and deleted it but still scanning. I would say at this rate it make take another hour....thanks will report back when thats done then i can do the command thing...otherwise might reinstall windows...anyway we will see

The 192..... doesn't really harm, cause this are private addresses and are not accessable from the internet.

So if you are connected to a router, you should configure the ip address of your router as the default gateway address in your ip configuration.
You can also configure the dns server with the ip address of your router.

But the best way is, to configure your computer to get these configuration via DHCP.
This presumes, that DHCP is enabled in the routers configuration.

It's just your external (public) IP you need to worry about. Your LAN IP is likely a private class C address in the 192.168.0.0/24 range.

Do you have a SOHO Router in your LAN that sits between the internet and your home network? If so, your default gateway address and DNS address should be the IP address of the LAN side of your router.

If you're able to get proper connectivity while connected to the wired interface of your laptop, compare the output of the ipconfig command to when you try it wirelessly and look for differences.

Oh to save you time putting information from a command prompt window up here, there's a quick and dirty method to copy/paste it from there to here and for info on how to copy/paste from a command prompt window click on my name above and read my "how-to" guide titled, "Post the output of ipconfig (version 2)"

Thanks i haven't read up about the privacy of all these numbers in years. Just remember way back posting something along these lines as was told not to post it in future :0)
Yep i have a router and the ethernet should just work for it. I only have a password/username situation for the wireless part of the router...i have plugged many computers and both desktop and laptops in with no hassles. The router is a belkin n1

So your issue is no longer to connect wired to the router (internet), but wireless?

OK things look promising but i am not quite there yet. For the ethernet it seems the drivers are not easily set with this model by just installing activating the exe file downloaded from the site. All of them for the hardware were a little finicky. Anyway seems the driver is a set of 3 types for different models and i can't seem to sort out which oe is for this machine. So i have the explanation mark in 'device manager' and can't get any further right now.
I also tried a wireless card that i have but i don't know what the ssid is and i put in a network key(is that the password for the router?) but that didn't work. I have never done any type of wireless connections at home with windows before so i really don't know what i am looking at. Is the SSID the name of the modem? When i click to connect the the seen wireless connection(yes it sees the router and names it in windows) i get an error saying 'wireless network connection. windows is unable to connect to the selected network, the network may no longer be in range. please refresh the list of available networks, and try to connect again. ' then there is an ok button.
I would prefer to get the ethernet port happening and not use wireless but it was a shot in the dark to see if i can get something happening.

The SSID is the name of your wireless network, configured in the routers setup.
The password you mentioned, is the encryption key, also defined in the routers setup for wireless network.

Wired network card:
To find the correct driver, you first have to clear up, whether the network card is onboard or it's an addon card.

If it's an onboard card, you should have a driver cd for your mainboard, which has all the needed drivers.
You can install the drivers from this cd.

Should work.

OK still don't know what the SSID is. I don't remember setting one...just a password.

Wired thing is onboard! I have no driver cd. I downloaded drivers from the manufacturers website i think i posted a link above somewhere and mentioned that. As i did say there are 3 drivers for the ethernet and i don't know which one is mine.

What about the users manual of the mainboard?
You should find the answer in there.

I found this page http://support.lenovo.com/en_US/det... and i had another look at the back of the lappie and all the numbers and info lead me to that it must be this model 2684–4Cx 802.11b....there is listed on the underside of the laptop the numbers : Type 2684 and then further down there is a CM and then further down there is 802.11 a/b MAC . The model is listed on page 143 of the manual...can't see where motherboards are directly mentioned. Culd this be it ? http://www.motherboardnow.com/IBM-T...

When you go to this website
http://support.lenovo.com/en_US/dow...

you can chose "Run Auto-Detect" (only works in Internet Explorer).
This should bring up you exact modell and the appropriate drivers.

Good objection :-)
Do you have any special software installed comming with your Lenove laptop.
Mostly the preinstall software to manage all the special funktions provided by your laptop.
Most likely, you'll find detailed information about your laptop, including the exact model and maybe the ethernet card of your laptop.
