Unidentified Network on Wired Ethernet

ping-ing 127.0.0.1 will alwyas get a response because it's a loopback address

are u unable to connect to the internet? can you ping www.tomshardware.com and get a response?

make sure your iPv4 ethernet settings is not set to manual and you do not have 2 ip's assigned to your nic

Thanks for the quick reply. I do not get a response when I ping www.tomshardware.com, and all my IPv4 settings are set to automatic.

what is your ip if you goto command prompt and type

ipconfig /all

- your wired ethernet controller IP

can u ping 10.12.16.1?

Nope, I get a "Destination host unreachable."

use the ip information to MANUALLY assign yourself the ip - reboot and try again

if your nic did not accept the changes then you should boot into safe mode and uninstall the drivers and nic, reboot, and then install the drivers again

do u have windows firewall or some other form of software firewall set up to allow the traffic to pass through that subnet?

Hi


Have you asked the college IT department for help and what you have to do to get on the network and then the internet ?


are you using a network cable which is known to work. ?
(some switches will auto detect a cross over cable others do not)

Hi Dingo, setting my IP manually and reinstalling drivers didn't work.   I haven't touched my firewall settings in ages so I'm not really sure about that part. I just have the regular Windows Firewall with probably default settings.

mbarnes, I have talked to the IT department a little bit because I used to think it was an issue on their end with the connection. But I've been here for 3 years and have never had an issue connecting to their wired network so I'm not sure how much they could help. My cable works because I've tried it with my laptop.

Bump!

have you confirmed that the card is actually working, by unplugging it and seeing if you lose IP information?

I find it hard to believe that suddenly you cannot access the internet, even after installing a brand new NIC.

It just doesn't add up... there's some part of the equation you haven't divulged, because any one of the suggestions, on top of what you've done already, should've worked

try bringing your computer to another room and using their cable - if it works, then you know to contact IT and have them fix it

SOLVED: another solution.

Appears some resolved this problem by removing Bonjour services. It didn't work for me.

I found an alternate solution of reinserting the network address under the advanced tab of the NIC card.: http://www.sevenforums.com/network-sharing/12759-possib...

One additional suggestion for those who, like me, limit router access to certain MAC addresses:

OMAR inserted a random 12 digit number. Instead insert the MAC address of the NIC. That is what is missing from the Device line of the ipconfig /all he refers to.

Hope this works for others as it did for me.
