FUCK! I found the model i have (DES-1105), the chump at OfficeMax told me
"this is all you need if you have two computers, a DSL box, and you want both to be able to connect at the same time to the interwebs"
So i buy it, and after all this long ass trouble shooting crap, i get this message on their tech support site (this is referring to my model of "router")
Question: Why canĀ“t I share my Internet connection to multiple computers when using my D-Link switch or hub?
Answer: If you are connecting directly to a Cable or DSL modem, you will need a router to share your Internet connection or a computer using ICS (Internet Connection Sharing) or Proxy. Switches and hubs do not allow you to share a single IP address to multiple computers.
The fucker sold me a HUB? WTF is that?! I said router, he handed me this piece of shit, and now i can't get internet on both computers. What a fucking rip. Good thing i kept the receipt, and i remembered the asshole's name too, that shit head "Eli"
