Unable To Make A Connection to Internet

[MaxArk]

Last evening after starting up my computer, I was unable to connect to the internet. After several reboots of the computer and modem, there was still no resolution. All the other network connected devices were able to maintain an internet connection through both wired and wireless connections.

My computer was telling me it was unable to find a network connection and that I should ensure a network cable was plugged in or to ensure it wasn't damaged. Neither the modem or adapter LEDs were illuminated to indicate a connection. I exchangeded my ethernet cable between the wall jack and my computer which made no difference. I disconnected the cable from my computer and and reconnected it to my laptop. I was able to make a connection. I concluded the issue was with my computer. Fearing that the onboard LAN adapter had failed, I went out and purchased a PCIe LAN adapter (TP-Link TG-3468 Network adapter) and installed it. The computer found it and installed drivers. Still, the problem persisted, Unable to find any connection.

A reboot of the modem and computer made no difference.

I disabled the onboard NIC through BIOS, uninstalled all instances of any network interfaces, and installed the drivers from the CD provided with the card. From there, a driver update attempt indicated the drivers were up to date. Still, unable to make a connection in either safe mode (with networking) or regular Windows 7 initialization. (Using Windows 7 64 bit OS)

A reboot of the modem and computer made no difference.

Tried: (as per https://support.microsoft.com/en-us/help/15287/windows-why-can-not-get-connected)

netsh winsock reset and the result was "The following command was not found: winsock refresh.

ipconfig /release and the result was "An error occurred while releasing interface Local Area Connection : An address has not yet been associated with the network endpoint."

Then, ipconfig /renew which resulted in "No operation can be performed on Local Area Network while it has its media disconnected. An error occurred while releasing interface Loopback Pseudo-Interface 1 : The system cannot find the file specified."

Followed finally with ipconfig /flushdns which indicated "Successfully flushed the DNS resolver cache."

I hope someone is able to help find a solution. I thank all those who have taken this post into consideration.

OK, so you know your router and cable are all well and very likely your LAN adapter(s) too. That really only leaves Windows and you have tried various ipconfig commands without success. In the end it may just be faster to reinstall Windows.

Telling someone to reinstall their operating system when they have a network issue is like telling someone to change car because they have a flat. seriously.

MaxArk,
You mention you tested the cable by using it on your laptop, did you use the same port on the router the desktop was using when you performed this test (trying to see if a port is dead on your router possibly)

That question has been answered already. Any other positive suggestions?

Hi folks ... I appreciate everyone's willingness to help. It is very frustrating, and relying on the internet for work, I am getting quite anxious.

Paladin .. yes, the cable that was attached to both the laptop and computer were both from the same port in the router. Would a Windows repair help? Unfortunately, much to my surprise, auto restore was turned off. I can't rely on going back in time to help resolve the problem. :-(

After some research, have you tried the following solution regarding your missing Winsock ?

Hi Paladin, thank you for your support.

Unfortunately, it appears that Fixit solution is no longer available. The manual instructions appear to be for Windows XP, so I'm not certain whether they would apply or not with my Windows 7 installation.

I tried a Windows repair which made no difference.

Last night, while trying to identify the cause, I stumbled on the likely culprit. Windows is reporting that I need to plug in a network cable. The network cable is clicked securely in place.

I had received this same error with both network cards, the online one and the one I purchased to replace it, the PCIe card. I have tried three different cables, from 3 different ports on my router with no resolution. I have no problem connecting with those same cables from any port on my router, to my laptop.

I;ve attempted a common online fix that was successful for many ... a simple solution involving unplugging the power and ethernet cables for 30+ minutes, followed by reconnection and rebooting. This made no difference regrettably.
