Waarom werkt internet niet op pc, maar op laptop wel?

[anoniem]

Ik heb hier een probleempje met mijn internetverbinding en ik hoop dat iemand me de gouden tip kan geven... Sinds eergisteren werkt de internetverbinding op mijn hoofd-pc thuis (de desktop) niet meer. Het ligt niet aan de internetprovider of aan de router want laptops die (wireless) aan de router hangen, daar werkt internet nog gewoon prima. Als ik de Windows 7 probleemoplosser er op los laat dan wordt vermeld: "De standaardgateway is niet beschikbaar". Wat betekent dit? Is de netwerkkaart kapot, of is het poortje waar de netwerkkabel in gaat kapot? De kabel is in ieder geval goed en bij het poortje brandt een groen lichtje en knippert er iets oranje... Bij status van de LAN-verbinding wordt vermeld: IPv4 verb. mogelijkheden: geen internettoegang IPv6 verb. mogelijkheden: geen netwerktoegang Kan iemand me in een paar stappen uitleggen hoe ik de internetverbinding weer up-and-running kan krijgen??

Zit in de McAfee virusscanner/firewall. Die blokeert waarschijnlijk het gehele internet (wel perfect tegen virussen natuurlijk). Conclusie: weg met McAfee en gewoon de windows of een andere gratis firewall gebruiken.
