I have a relatively new Acer Veriton i5 pc with Windows 7 64 Bit Professional. Several days ago network connectivity essentially vanished (after working fine for about 2 months.) When I trouble shot the problem with Win7 utilities it said there was a problem with the driver or that the wireless card was faulty. After reinstalling the wireless adapter several times, I became convinced it must be faulty and bought a new one, the problem persisted. I then decided to try using the wired ethernet port and connecting to the router via a wired connection. The wired ethernet connection does not function either. Basically this machine has suddenly lost the ability to connect to a network. I tried going back to a restore point in the past. - Did not work I tried refreshing the TCP/IP stack. Did not work (I may not have done this correctly) I tried manually entering IP information in the Network Cards directly (it did not work) I tried "Fixit" utility you can download for MS Support site. Finally, yesterday I decided to do a complete re-install of the OS. This did not work. So I have been researching Win 7 Networking problems and it appears that there have been persistent networking issues with Win 7 and these networking problems are apparently frustratingly difficult to resolve (certainly that's been my experience.) When I go to the command prompt and enter the ipconfig command, there does not appear to be any IP service running at all. I am completely stumped. Any assistance from this forum would be greatly appreciated. Respectfully Matthew

What does the connectivity icon in the taskbar showing? Does it have a warning sign on it? Are you plugged into the router directly (when you using a wired connection) or is there a switch in between? Also, please try the following Connect the machine to your router directly (if possible) and try to obtain an ip address via dhcp Run Ipconfig /all with dhcp turned on and post the results Repeat the procedure with a static ip assigned to the Ethernet

Hi Justinian81 , What does the connectivity icon in the task bar show? Answer: It shows what looks like an RJ45/Ethernet connector symbol with a red X through it. It says "Not connected and no connections available." The repair utility says the cable is not connected, even though it is. Does it have a warning sign on it? Answer: A red X. Are you plugged into the router directly (when you using a wired connection) or is there a switch in between? Answer: I'm plugged into a switch port of a combo D-Link DIR 615 Router Switch. I did try connecting directly into the Cable Modem and again it just says there's no connection.

Ok, the ipconfig is helpful. Have you tested this with a different ethernet cable? I would also test the cable with two different nics if possible.

I tried two different cables. Both cables do work with other devices and one of the cables was used previously for this nic and worked.

How about testing with a different nic?

I have used 2 different nics, 3 if you count the integrated ethernet port. Networking services on the machine are just gone, it's not the networking equipment, it's the machine and more specifically the Windows 7 Operating System. Evidently there is an ongoing problem with networking issues and Windows 7 and it's not been resolved and can't readily be resolved by the end user (even a fairly experienced one.)
