Hej Jakob,
Jeg har fundet hvad der ligner løsningen på dit problem. Nu er det jo efterhånden et meget gammelt spørgsmål, men da jeg synes lige du skal have det alligevel.
Du skal en tur i registreringsdatabasen for at få det til at virke.
Før du går i gang skal du oprette et gendannelsespunkt (Start->Programmet->Tilbehør->Systemværktøjer->Systemgendannelse)
Det er også en god idé at tage backup af din registreringsdatabase, du kan se i vejledningen nedenfor hvordan. Vejledningen er på engelsk, men den er ikke svær at følge. Here goes:

This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

To resolve this issue, disable the DHCP BROADCAST flag in Windows Vista. To do this, follow these steps:
1. Click Start, type regedit in the Start Search box, and then click regedit in the Programs list.
If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}
In this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.
3. On the Edit menu, point to New, and then click DWORD (32-bit) Value.
4. In the New Value #1 box, type DhcpConnEnableBcastFlagToggle, and then press ENTER.
5. Right-click DhcpConnEnableBcastFlagToggle, and then click Modify.
6. In the Value data box, type 1, and then click OK.
7. Close Registry Editor.
By setting this registry key to 1, Windows Vista will first try to obtain an IP address by using the BROADCAST flag in DHCP Discover packets. If that fails, it will try to obtain an IP address without using the BROADCAST flag in DHCP Discover packets.

Prøv så at genstarte både computer og router og log på igen.
