I'm currently trying to connect my work laptop to my home network. It works fine when I connect to a Linksys router via wireless connection (At my brother's place).
At home I have a D-Link DIR 655 Xtreme N router. Everything works fine from my desktop, my ps3, when I have guests come over with their laptops, they're able to basically just plug in a spare ethernet cable and connect. It's not that simple with my work laptop for some reason.
It's running on windows XP Professional SP3 (I've researched and seen that SP2 had some known issue that should have been resolved with SP3)
I also tried ipconfig /renew "Local Area Network 2" and the message I get says "Adapter Local Area Connection 2 is not enabled for DHCP.
I was able to enable DHCP however now it says "Unable to contact your DHCP server" in the command prompt when I try to renew. I've also tried simply using the repair function (right click and select repair" but it errors out when attempting to renew my IP.
The router is DHCP enabled.
