Connecting Wireless Router

Hi. Sorry if this is the wrong place to put this topic but I felt it was the right place.
Basically, my computer needed a new PCI network card but my only local PC shop didnt have any so i bought a wireless router instead. I can't get this router working though.

I thought that I could just plug an ethernet cable from the wireless router into my PC which are both in my bedroom, then run the install CD and connect to the wireless modem router downstairs. I always connected to the wireless modem router downstairs with my network card but when I try to run the install CD for the router it says -

"The ethernet adapter is either disabled or no ethernet adapter is installed on this computer. Either enable or add an ethernet adapter and run the application again."

The model of the wireless router is 'Netgear N150 wireless router'. Any help would be greatly appreciated as I dont want the money I spent to go to waste. :P

Thanks in advance.

Hi. Yeah i have a wireless router upstairs in my room which I'm trying to connect wirelessly to my wireless modem router downstairs which is connected to the internet.

Hope that diagram kinda helped. Thanks for the help.

Oh wow that sucks. Thanks for the help anyway, I appreciate it!

One last question, the one downstairs is a 'modem router'. I'm not sure what that is tbh but would it make a difference?

The modem router is a belkin dg834g.

You mention a network card in your first paragraph, but nothing further. How do you know the PCI NIC is bad? If you couldn't get the new NIC, are you still using that, or do you additionally have a wireless capable NIC as well? How did your system connect to the internet before? Could it connect from the bedroom? How does buying a wireless router solve your bad NIC? Desktop or laptop? Give us all details possible.

I had a wireless network card in my computer, but my computer crashed alot from an outdated driver that the network card used, so I was adviced to replace the network card. PC World, the only computer store near me, didnt have any wireless network cards so I bought a wireless router thinking that I could easily connect this to the wireless modem router downstairs wirelessly, but I was wrong and I'm now down £30 with a wireless router I dont need.
