Good afternoon

My notebook is Acer 8930G and my network adapter is an Atheros AR8121/AR8113/AR8114 and i used to have as a wired router a Dlink 524T, which i changed with a Netgear DG834 during my many attempts to resolve in vain my internet problems as i did with my ethernet cables.

About a week ago,suddenly my notebook ceased to have any internet connection and my status varied from local only to limited connectivity while both the green and orange lights on the adapter came and went continiously.
After a casual scan with Malwarebytez antispyware,it turned out that i had 9 infections from the trojan BHO.After innumerable efforts and formats,i somehow cleaned(so it seems without being 100% certain) my PC.The only thing is that the problem persists with the connection,while two other computers that share the network with me didn't have any problems whatsoever.

Is it possible that my ethernet card was damaged by the trojan?If anyone could help me out or at least enlighten me,i would be much obliged!!!!

Thanks in advance

is there any response when you plug in the cable? it is unlikely that a virus would have damaged the hardware, although it is possible that it released the ip address or edited the MAC address, if you plug in the cable to a different computer then does it work, and if you try a different cable in that computer, does anything happen.

If anyone has been changing settings on your router it is possible to assign an IP address using the router, so that every time a particular computer requests an IP address it gets the same one, i find this prevents good network communication, so you could try undoing this, otherwise there is an equivalent settings in windows, but it must be undone on both the router and windows to make this work.

You can try opening network connections, open the properties of the connection and in the 'the connection uses the following...", click Internet Protocol(TCP/IP) and click properties. then highlight the obtain an IP addres automatically and obtain a DNS server automatically boxes, click OK and try again, if that doesn't work, try the following.

Open command prompt as an Administrator, type "ipconifg /all" without the quotes, then see whether it says there is an ip address, if not, type "ipconfig /release" again without the quotes, it should have a think, then type "ipconfig /renew" and it should again have a pause. once this is finished, try accesing the network again.

post again when you know if either of these worked.

Failure is not an option, it comes as Standard with all Windows Operating Systems
