Internet problem

Expand Post »

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

Re: Internet problem

I assumed your laptop is wired. See if you can plug you data cable to a diffrent port on you router then reboot. If that didn't work replace your data cable and reboot.

If the above didn't work post a reply we gonna go to the next step.

Re: Internet problem

first and foremost update your Ethernet drivers, the next thing will be configure your Internet Connection again. Third is try to use a good firewall line zone alarm.

I updated the drivers and configured the connection through the router settings page.When the problem first appeared,i was using Karspersky....

Re: Internet problem

Connect your laptop to the router and run ipconfig/all.
