Hi, I have LG notebook laptop.. it was working fine till I suddenly can't see my own ip operator icon.. and I can't connect to any internet. I tried to download realtek network driver also but it didn't help.. when I write cmd in run.. and type ipconfig.. it shows that I have internal error.. can anyone help?

I would check device manager, check and reininstall driver(s) if necessary. Reboot, Restore?

I tried that as well, but it won't work still..

When are you getting the internal error?

When I click on start-run and type cmd.. it takes me to windows system.. where I type ipconfig
And it shows me I have internal error..
When I check my network card, it shows me they are effected.. I can't understand how to solve the problem.. it's not showing my ip operator either.. when I restart laptop it says reinstall ip.. I tried to do that but didn't help.. :(
